Peter Morgan Alonso (born December 7, 1994), nicknamed "Polar Bear", is an American professional baseball first baseman for the New York Mets of Major League Baseball (MLB).
Alonso played college baseball for the Florida Gators before the Mets selected him in the 2016 MLB draft. He made his MLB debut on Opening Day in 2019 and won the National League's Rookie of the Year award that year, setting a major league record for rookies with 53 home runs.

## Early life

Peter “Pete” Morgan Alonso was born on December 7, 1994, in Tampa, Florida. Alonso attended Jesuit High School in Tampa for his first two years of high school, and transferred to Henry B. Plant High School in Tampa to finish high school. He played lacrosse and football as a freshman before deciding to focus solely on baseball. For the baseball team, he was a third baseman.
His grandfather, Peter Conrad Alonso, was a Spanish refugee who fled Barcelona during the Spanish Civil War to New York City through Ellis Island, settled in Queens, which is a borough of New York City and became a huge Brooklyn Dodgers fan. He attended Jamaica High School but his education was cut short due to his military service in World War II from 1942 to 1945 but continued his education at New York University earning multiple degrees, where he met Anna (née Pirraglia, of Italian descent) who he married in 1951 and settled down on Long Island begetting three daughters and Peter Matthew, Pete Alonso's father, before resettling the family to Lancaster, Ohio in 1963. Later, his father met and married his mother, Michelle Lynn Alonso (née Morgan), a Ohio native who was a student-athlete at Ohio Wesleyan University having played college softball.

## College career

Alonso enrolled at the University of Florida, where he played college baseball for the Florida Gators as a first baseman. He was named All-Southeastern Conference in his freshman year. In 2014, he played collegiate summer baseball with the Madison Mallards of the Northwoods League, and he was inducted into their Hall of Fame in 2024. In the summer of 2015, he played for the Bourne Braves of the Cape Cod Baseball League. In 2016, his junior year, he hit .374/.469/.659 with 14 home runs and 60 RBIs in 58 games. He competed for Florida in the 2015 and 2016 College World Series.

## Professional career
### Draft and minor leagues

The New York Mets selected Alonso in the second round of the 2016 Major League Baseball draft with the 64th overall pick. He signed with the Mets for a $909,200 signing bonus, and made his professional debut in 2016 with the Brooklyn Cyclones of the Class A Short Season New York–Penn League. He posted a .322 batting average with 5 home runs and 21 RBIs in 30 games and was chosen to participate in the league's All-Star Game.

He began the 2018 season in Binghamton, and received a midseason promotion to the Las Vegas 51s of the Class AAA Pacific Coast League. He represented the Mets in the 2018 All-Star Futures Game. In 132 games between Binghamton and Las Vegas, he slashed .285/.395/.579 with 36 home runs and 119 RBIs. He won the Joe Bauman Home Run Award. That season, Alonso was the final batter in Cashman Field history, as he hit a walk-off home run in the bottom of the 9th inning during the last baseball game played at the facility.

### New York Mets (2019–present)
#### 2019

Alonso made the Mets Opening Day roster in 2019 as the starting first baseman. He was in the team's starting lineup on Opening Day on March 28, and recorded his first major league hit against Washington Nationals pitcher Justin Miller in the eighth inning. Alonso hit his first major league home run on April 1 off of Drew Steckenrider of the Miami Marlins. On April 9, Alonso had his first career multi-home run game against the Minnesota Twins.
Alonso became the first player in MLB history since 1900 with 11 extra-base hits in his first 10 career games. No other player ever had more than nine. In April, he batted .292 with 9 home runs, 8 doubles, one triple and 26 RBIs in his first games in the big leagues. Alonso won the National League Rookie of the Month Award for April. His nine home runs led all MLB rookies and are tied for the most by a Mets player before May 1 with Neil Walker (2016), John Buck (2013), Carlos Delgado (2006), and Dave Kingman (1976).
On June 22, Alonso hit his 26th home run, breaking the National League record for most home runs by a rookie before the All-Star break, passing Cody Bellinger. The next day, with his 27th home run, he broke the Mets rookie home run record, previously set by Darryl Strawberry in 1983. Alonso was selected as a reserve to the 2019 All-Star Game. He also won the NL Rookie of the Month Award for the month of June.
On July 7, Alonso became the second player in Mets history to hit the most home runs (30) before the All-Star break, after Dave Kingman (1976). On July 8, Alonso won the 2019 MLB Home Run Derby, defeating Toronto Blue Jays first baseman Vladimir Guerrero Jr. 23–22 in the final round, becoming only the second rookie, after Aaron Judge, to win the Derby outright. On the way to the final round, Alonso also beat Carlos Santana and Ronald Acuña Jr., hitting 57 total home runs during the entire Derby.
On August 15, Alonso hit his 39th home run, tying Cody Bellinger for the most home runs by a rookie in National League history. Alonso finished the game with a career-high 5 hits and 6 RBIs. He broke Bellinger's record on August 18 with his 40th home run in an 11–5 win against the Kansas City Royals. On August 27, Alonso hit his 42nd home run to become the Mets all-time single-season home run leader, surpassing Carlos Beltrán and Todd Hundley. He is the first rookie to set his franchise's single-season home run record since Johnny Rizzo did it for the Pittsburgh Pirates in 1938.
On September 27, Alonso hit his 52nd home run of the season, tying Aaron Judge for the most home runs by a rookie in MLB history. He hit his 53rd the next day off of pitcher Mike Foltynewicz to break Judge's record. Alonso's 53 home runs led all of MLB for the 2019 season. On November 11, Alonso was awarded the National League Rookie of the Year, receiving 29 of 30 first-place votes. On December 10, Alonso was named to the first team of the inaugural All-MLB Team.

#### 2020

On September 3, 2020, Alonso hit his first career walk-off home run in a 9–7 victory against their crosstown rival New York Yankees. His sophomore season was a step back from his breakout rookie year; Danny Abriano of Yahoo Sports called it "a season to forget." However, he had the highest maximum exit velocity of all major league hitters, at 118.4 miles per hour (190.5 km/h). In the 2020 season shortened by COVID-19, Alonso played in 57 games and batted .231/.326/.490 with 16 home runs and 35 RBIs.
Alonso's sophomore slump coupled with a second consecutive breakout season from Dominic Smith led some talent evaluators to favor the latter as the team's starting first baseman heading into the 2021 season.

#### 2021

On July 12, Alonso won his second straight Home Run Derby after defeating Baltimore Orioles first baseman Trey Mancini 23–22 in the final round. He became the third player ever to win back-to-back Derbies, as well as the fourth player to win two Derbies (after Ken Griffey Jr., Prince Fielder, and Yoenis Céspedes). Newsday Mets beat writer Tim Healey noted Alonso has earned $2 million from winning the Derby twice while making $1.47 million from 2019–2021 in base salary while playing for the Mets.
On September 7, Alonso hit his 100th career home run, off of Miami Marlins pitcher Edward Cabrera. He accomplished the feat in 347 games, becoming the second-fastest player to reach 100 career home runs behind Ryan Howard, who did it in 325 games. Alonso played in 152 games for the Mets in 2021, batting .262/.344/.519 with 37 home runs and 94 RBIs.

#### 2022

On March 22, 2022, Alonso signed a $7.4 million contract with the Mets, avoiding salary arbitration. He hit his first career grand slam on April 9 against the Washington Nationals off of pitcher Joan Adon in the 5th inning, leading the Mets to a 5–0 victory.
On July 10, Alonso was named to the 2022 MLB All-Star Game, the second selection of his career. He participated in the Home Run Derby, making it to the semifinals, but lost to Julio Rodríguez. In a September 25 game against the Oakland Athletics, Alonso drove in 5 runs, setting a new Mets' single-season RBI record with 125. He broke the record on a 451-foot (137 m) two-run home run in the 4th inning off of pitcher Norge Ruiz. The Mets previous RBI record was held by Mike Piazza (1999) and David Wright (2008).
On September 27 against the Miami Marlins, Alonso hit his 40th home run of the season, becoming the first Mets player to accomplish the feat twice. In 2022, Alonso batted .271/.352/.518 with 40 home runs and 131 RBIs, breaking the franchise record and tying Aaron Judge for the most RBI in the major leagues.

#### 2023

On January 13, 2023, Alonso and the Mets agreed to a one-year, $14.5 million contract during the arbitration period. On April 7, during a game against the Miami Marlins, Alonso hit his 150th career home run, passing Carlos Beltrán for 6th place on the Mets all-time home run list. He also became the second fastest player to 150 home runs (in 538 games) since Ryan Howard (495 games).
On June 7, Alonso was placed on the injured list when he suffered a bone bruise and left wrist sprain after being hit by a pitch. He was expected to miss 3–4 weeks due to the injury, but recovered in just eleven days and was activated from the IL on June 18.
On July 2, Alonso was named to the MLB All-Star Game for the third time in his career, joining Keith Hernandez as the only two Mets first basemen to be named to three All-Star teams.
On September 3, during a game against the Seattle Mariners, Alonso homered twice and drove in 4 runs, reaching 40-plus home runs and 100 RBIs for the second consecutive season. His two-run shot made him the fifth player in Major League history with at least three 40-home run seasons in his first five seasons of their career, joining Ralph Kiner (4 seasons), Eddie Mathews, Ryan Howard, and Albert Pujols (each with 3 seasons).
On September 27, Alonso hit his 46th home run of the season in an 11–2 win over the Miami Marlins. His 192nd career homer made him tie Howard Johnson for 4th place on the Mets all-time home run list. Alonso played in 154 games for the Mets in 2023, batting .217/.318/.504 with 46 home runs and 118 RBI.

#### 2024

On January 11, 2024, the Mets and Alonso agreed on a one-year, $20.5 million contract to avoid salary arbitration. On April 4, during a game against the Detroit Tigers, Alonso recorded his 500th career RBI on a game-tying home run off of pitcher Alex Faedo, becoming the 10th and fastest player in Mets history to achieve the milestone. He won NL Player of the Week honors on April 15. On April 27 against the St. Louis Cardinals, Alonso hit his 200th career home run, off of pitcher Sonny Gray. He became the fourth-fastest player in MLB history to hit 200 home runs and the 4th Met to hit 200 career home runs.
On May 14, it was reported online that the Mets made an attempt to extend Alonso the previous season but they were unsuccessful, as he turned down a seven-year, $158 million contract extension from the team.
On July 7, Alonso was named to the 2024 MLB All-Star Game, passing Keith Hernandez for the most appearances by a Mets first baseman.
Alonso hit his 220th career home run on August 27 against the Arizona Diamondbacks, tying Mike Piazza for 3rd-place on the Mets all-time home run list. Two days later, he would hit his 221st career homer, passing Piazza.
In 2024, Alonso played in all 162 games for the Mets, making him the second player in Mets history to appear in every game in a single-season, joining Félix Millán (1975). He finished the season batting .240/.329/.459 with 34 home runs and 88 RBI.
On October 3, in Game 3 the 2024 National League Wild Card Series against the Milwaukee Brewers, with the Mets down 2–0 in the top of the 9th inning, Alonso hit a go-ahead, three-run home run to give the Mets a 3–2 lead. They would then go on to win 4–2 and eliminate the Brewers from the playoffs. With that home run, Alonso became the first major league player in history to hit a go-ahead homer while trailing in the ninth inning or later of a winner-take-all postseason game.
In the 2024 MLB postseason, Alonso played in 13 games for the Mets, batting .273/.431/.568 with 4 home runs and 10 RBI.

#### 2025

On February 12, 2025, after three months of back-and-forth negotiations with his agent Scott Boras, Alonso and the Mets agreed to a two-year, $54 million contract including an opt-out after the 2025 season.

## International career

On August 17, 2022, Alonso announced that he would also join the United States national baseball team in the 2023 World Baseball Classic. Alonso went 2-for-14 across five games, most notably starting an eighth inning rally with a base hit against Venezuela in the quarterfinals, and later hitting an RBI single against Cuba in the semifinals.

## Personal life

Alonso first got his "Polar Bear" nickname when he was a top prospect. He made such a big impression during spring training in 2019 that Mets third baseman Todd Frazier, who was known for giving players nicknames, is the one who coined it. Frazier said to Alonso, "You look like a big, damn polar bear." "And then it just kind of stuck," Alonso said during his rookie season.
Alonso married Haley Walsh on November 12, 2021, at Sacred Heart Catholic Church in downtown Tampa. She is originally from Boston; they met in the summer of 2015 while he was playing in the Cape Cod collegiate summer league. They carried on a long-distance relationship while he continued at the University of Florida and she attended Michigan State University. They were engaged in November 2018.
In 2020, the couple formed The Alonso Foundation, a charitable organization that supports youth, veteran, and animal causes.
On March 13, 2022, Alonso was involved in a car accident in Tampa, Florida, which he described as a "really close experience to death." A driver ran a red light and struck Alonso's vehicle, which flipped over three times. Neither Alonso nor anyone else involved in the incident was injured.
An avid outdoorsman, he enjoys hunting and fishing. He was also featured in a season 9 episode of MeatEater in which he hunted mule deer in Colorado with Steven Rinella.
