2024 Houston Astros season

The 2024 Houston Astros season was the 63rd season for the Major League Baseball (MLB) franchise located in Houston, Texas, their 60th as the Astros, 12th in both the American League (AL) and AL West division, and 25th at Minute Maid Park. They entered the season as the defending AL West champions and runners-up of the American League.
The 2024 season was the first for the Space City Home Network (SCHN) to televise Astros games, who, with the Houston Rockets of the National Basketball Association (NBA), created after acquiring and rebranding the regional sports network AT&T SportsNet Southwest from Warner Bros. Discovery. The Astros promoted bench coach Joe Espada as the 25th manager in franchise history, replacing Dusty Baker.
On April 1, pitcher Ronel Blanco threw the 17th no-hitter in Astros history against the Toronto Blue Jays. It was also the earliest date a no-hitter has been thrown in MLB history. More history was made as the no-hitter marked Espada's first career win as manager, the first occurrence in MLB history where a manager got his first win with a no-hitter.
The Astros had a slow start to the season, as they fell to 12–24 after their first 36 games. The largest deficit by which the Astros trailed in the AL West was 10 games on June 18, when their record was 33–40. Following a seven-game winning streak, on June 26, the Astros claimed their 40th win to reach .500 for the first time on the season.
Jose Altuve, Yordan Alvarez, and Kyle Tucker were each named to the AL All-Star team. Walker Janek, a catcher from Sam Houston State, was the Astros' top selection from the 2024 MLB draft, at number 28 overall. On July 21 at T-Mobile Park, Alvarez hit for the cycle, the tenth occurrence in franchise history. The Astros' pitching staff produced a record-setting August and threw three additional no-hit bids of 7+2⁄3 innings or more, including one by starting pitcher Spencer Arrighetti, who was named AL Rookie of the Month. Meanwhile, closer Josh Hader was AL Reliever of the Month.
On September 13, the Astros beat the Los Angeles Angels to attain the 5,000th win in franchise history, becoming only the second expansion team to do so.
On September 24, the Astros clinched the AL West division title for the fourth consecutive season and the seventh in the past eight seasons. They also clinched a postseason berth for the eighth consecutive season and the ninth in the past 10 seasons. On September 29, the Astros season finale against the Cleveland Guardians was canceled due to weather concerns. As such, the Astros finished with an 88–73 record and did not play the season finale. The Astros were the fifth team to start 22–28 and win their division in MLB history. The Astros were swept by the Detroit Tigers in the 2024 American League Wild Card Series, ending their streak of consecutive ALCS appearances at seven (2017–2023), which was the most in the American League and the second-most consecutive LCS appearances after the Atlanta Braves' consecutive NLCS appearances of eight (1991–1999, excluding 1994 that was not played due to a players' strike). The Astros were also swept in a postseason series for the first time since the 2005 World Series.
Following the season, Alex Bregman won his first career Gold Glove Award, Altuve won his seventh career Silver Slugger Award, while Altuve, Alvarez, and Opening Day starting pitcher Framber Valdez were each named to the All-MLB Team Second Team. Altuve's ninth career All-Star selection and seventh Silver Slugger both extended franchise records.
The Houston Astros finished the 2023 season as runner up for the American League (AL) pennant behind the defending World Series champions Texas Rangers. The Astros entered the offseason with uncertainty at the managerial position as Dusty Baker had completed the last year of his contract and had expressed to multiple people inside and outside the organization that 2023 was to be his last year managing the club.
On October 25, it was announced that Baker would retire as manager of the Astros. The Astros posted a 320–226 (.586) record with Baker as manager, winning a World Series (2022) and two AL pennants (2021, 2022).
On November 13, it was announced that bench coach Joe Espada, who had been with the organization since the 2018 season, would be named the new manager of the Astros.
On December 6, the Astros announced that they had acquired right-handed pitcher Dylan Coleman from the Kansas City Royals in exchange for minor league pitcher Carlos Mateo.
The following day, the team officially announced that they had signed catcher Víctor Caratini to a two-year contract worth $12 million.
On January 16, the team announced that reliever Kendall Graveman was set to miss the entire 2024 season after undergoing surgery on his shoulder.
Six days later, on January 22, the team announced that they had signed left-handed pitcher Josh Hader to a five-year contract worth $95 million.
On January 31, the Astros acquired Trey Cabbage from the Los Angeles Angels in exchange for minor league pitcher Carlos Espinosa.
On February 6, the team announced that they had extended 2nd baseman Jose Altuve for five years and $125 million.
Per Forbes, the Astros' net value was estimated at $2.425 billion, ranking 11th MLB. The Astros partnered with the Houston Rockets of the National Basketball Association (NBA) to acquire regional sports network AT&T SportsNet Southwest and rebrand it as Space City Home Network (SCHN). The network was launched to the public on October 3, 2023, the 2024 season was the first season for the Astros to broadcast on SCHN. The moves implied a loss of an estimated $23 million of revenue; however, Warner Bros. Discovery (WBD) had announced they would discontinue broadcasts for Houston, the Colorado Rockies, Texas Rangers, and other clubs, leaving no airing of home games for those respective clubs.
The Astros kicked off their spring training against the Washington Nationals on February 24.
Right handers Lance McCullers Jr. and Luis García entered the 2024 season rehabilitating elbow injuries. García was recovvering from ulnar collateral ligament reconstruction (UCL reconstruction, also known as Tommy John surgery), for an injury sustained early in May 2023. He was expected to miss the start of the 2024 season. McCullers was recovering from a flexor tendon strain first sustained in the 2021 American League Division Series (ALDS) and had not appeared in a major league game since the 2022 World Series. In February 2023, he strained it again and elected for season-ending surgery the following June.
Three-time Cy Young Award winner Justin Verlander also missed the start of the season due to right shoulder inflammation.
By making the Opening Day roster and playing for the Astros, right-handed relief pitcher Tayler Scott became the first South African to play for Houston. Also the first South African pitcher in MLB history, he made his MLB debut in 2019, pitched for six teams, and an additional two years in Nippon Professional Baseball (NPB), before joining Houston.

The Astros dropped their Opening Day game, March 28, to the New York Yankees, 5–4. In the ninth inning, Kyle Tucker singled with Mauricio Dubón and Yordan Alvarez on base. However, right fielder Juan Soto delivered an accurate throw to home plate that allowed catcher Jose Trevino tag out Dubón to preserve the Yankees' lead and eventual victory.
The Yankees swept the opening 4-game series, led by Soto's 9-for-17 (.529 batting average) and 4 runs batted in (RBI). The Astros' seventh loss in a row to the Yankees, it was the first time they dropped their first four to begin a season since 2011 (0–5).
On April 1, Ronel Blanco (1–0) no-hit the Toronto Blue Jays to lead a 10–0 rout for Astros' first win of the season, the first win for Joe Espada as manager and the earliest calendar-date no-hitter in MLB history. The eighth career major league start and first of the season for Blanco, it was the 17th no-hitter in franchise history. Espada became the first manager to earn his premier major league victory via the no-hitter, per the Elias Sports Bureau (ESB). Kyle Tucker led Houston's offense with two home runs. On April 3, Cristian Javier (1–0) and four relievers combined on a one-hit, 8–0 shutout of Toronto: Javier pitched the first five innings, allowing the one hit, and Seth Martinez, Rafael Montero, Tayler Scott, and Dylan Coleman each tossed an inning. Coleman made his Astros debut this game. Yordan Alvarez homered twice and tied a career-high with four hits, his 16th career multi-homer and sixth four-hit game. Jose Altuve and Jeremy Peña also homered for the Astros.
In his next start on April 7, Blanco tossed another 5+2⁄3 no-hit innings until a single hit by Adolis García of the Texas Rangers ended 14+2⁄3 consecutive no-hit innings. Blanco set an expansion-era record of 44 outs recorded to begin a season before allowing a hit. With Framber Valdez being skipped from making his start on April 8 due elbow soreness, Blair Henley made major league debut versus the Rangers. He retired just one of nine batters faced and allowed five runs as the Astros trailed 5–2 after one inning. Alvarez collected three hits, including a home run, and Victor Caratini hit a three-run home run as the Astros came back to win, 10–5. Seth Martinez (1–0) worked 3+2⁄3 scoreless innings, and Scott and Brandon Bielak each worked an additional two innings.

On April 10, Spencer Arrighetti made his major league debut for the Astros, as the starting pitcher versus the Kansas City Royals at Kauffman Stadium. The Royals staked seven runs in the third inning, which finished Arrighetti's outing. The Royals won, 11–2, and extended a winning streak to 6 consecutive. The Royals continued their hot hitting the following day. They collected 11 hits in the first inning alone versus starter Hunter Brown, who became the first pitcher in major league history to allow 11 hits in less than one inning, which then led to nine runs. Brown tallied 2⁄3 inning before being removed.

In the tenth, Caratini's walk-off, pinch hit home run in the 10th inning secured a 10–9 final to give the Astros (10–19) their first three-game winning streak of the season. Josh Hader (1–2) picked up the ninth and tenth innings for his first two-inning relief outing since 2019, and his first win in an Astros uniform.

Meyers' home run highlighted a six-run fourth inning for the Astros. Verlander (3–2) struck out Abraham Toro to pass Hall of Famer Greg Maddux (3,371) for 10th place on the all-time strikeout list, finishing the outing with 3,377, and won the 260th game of his career. Toro had been instrumental in securing Verlander's third no-hitter in Toronto in 2019, hitting a home run in the ninth inning that accounted for the only runs of the contest for a 2–0 Astros' final, as well as fielding the final out of the game.
On June 3, Alex Bregman hit a game-tying home run leading off the eighth inning and Yainer Díaz homered that same inning to lead a 7–4 win over the St. Louis Cardinals.

Kyle Tucker was removed from the game on June 7 versus the Los Angeles Angels due to a shin contusion as a result of a foul ball hit off his right leg, and was later placed on the 10-day injured list (IL). His 19 home runs tied for second in the AL with Gunnar Henderson and Tucker was fourth in OPS at .979. In early September as Tucker still had to yet to be activated, the extent of the injury was revealed to be a fracture, though that was indiscernible from early radiologic scans.
The Astros released Jose Abreu on June 14, nearly at the halfway point of a 3-year, $58.5 million contract signed during the 2022–23 offseason. In 714 regular season plate appearances in an Astros uniform, he slashed .217/.275/.351.
Victor Caratini hit his first major league triple on June 15 off Jack Flaherty in 12–5 loss to the Detroit Tigers at Minute Maid Park. Ronel Blanco tossed seven hitless innings versus Detroit on June 16 before Ryan Pressly allowed a single by Wenceel Pérez for Detroit's with two outs in the eighth.
Following a 2–0 shutout defeat to the Chicago White Sox in a series opener on June 18, the Astros' record was 33–40, distancing them 10 games from the Seattle Mariners for the AL West lead, their largest deficit of the season. It was the first time since the final day of the 2016 season that Houston was 10 games behind for the division lead. The Astros also placed ace Justin Verlander on the injured list. The following day, Hunter Brown (4–5) pitched six strong innings with one run allowed, catcher César Salazar drove in 2 runs with his first career multi-hit game in the majors, and Jake Meyers scored two runs on a pair of doubles to end an 0–17 slump.

Arrighetti (4–6) set a personal achievement with 10 strikeouts, which also set the highest for the Astros' rotation for the season to date.
On June 30, Altuve was ejected from the game against the New York Mets after arguing that a ball he had hit was not in play. He was ruled thrown out on a ground ball to Mark Vientos, but did not run out the batted ball after it instead appeared to have struck his left foot.

Since his last start in April, Brown was 8–2, 2.55 ERA, and 1.12 WHIP in 14 games and 13 starts. Yainer Díaz hit a two-run single to lead the Astros' offense. With this win, the Astros evaporated a 10-game deficit to the then-first place Mariners in a span of 24 games, which was the quickest that large of a lead was eliminated in major league history, per the ESB.
On July 21, Álvarez hit for the cycle at T-Mobile Park, the first of his career, in a loss 6–4 to Seattle. It was the 10th cycle in franchise history and first since Altuve hit one August 28, 2023, versus Boston.

He became the first Japanese-born pitcher in club history to start a game. Second, he tied a franchise record with eight consecutive strikeouts, of which that streak ended on a full count walk to Yandy Díaz. By tallying 11 total strikeouts, he had the most in an Astros debut since Gerrit Cole on April 1, 2018, and to that point, Kikuchi's total represented the season high for the staff. He exited after 5+2⁄3 innings and allowing three hits, two runs, and two walks in a contest the Astros held on to win, 3–2.

Mauricio Dubón ended an 0-for-14 slump when he hit an RBI single up the middle in the top of the 10th. Jeremy Peña’s leadoff home run in the top of the fifth against Rays starter Zack Littell was the Astros' only other hit, marking the first time in club history they won in extra innings with fewer than three hits. The last time the Astros won a game with just two hits was on September 5, 2017.
