John Nicklaus Hoover (December 22, 1962 – July 8, 2014) was the Major League Baseball No. 25 draft choice in the first round in 1984 (by Baltimore), after having led the nation in strikeouts in college baseball, pitching 205 strikeouts for Fresno State in his senior year.
 Also in 1984 Hoover was a starting pitcher for the United States Olympic baseball team, winning the opening game and helping the US to win the silver medal for baseball.
 His teammates on the Olympic team included Mark McGwire, Barry Larkin, Will Clark, and Oddibe McDowell.
The Commissioner's Historic Achievement Award is awarded by the Commissioner of Baseball to a group or person who has made a "major impact on the sport" of baseball.
 It is not an annual award; rather, the Commissioner presents the trophy at his discretion.
 The trophy is a gold baseball sitting atop a cylindrical silver base, created by Tiffany & Co. The award has been presented fourteen times by Commissioner Bud Selig: eleven times to players, once to a team, and twice to a non-player.
 Mark McGwire and Sammy Sosa were the first to receive the award for their parts in the 1998 MLB home run record chase.
 The most recent recipient is Derek Jeter (2014), who was honored in the final year of his career for being "one of the most accomplished shortstops of all-time".
 The 2001 Seattle Mariners won the award as a team for posting a 116–46 record one season after losing Alex Rodriguez to the Texas Rangers.
 Roberto Clemente, the 2006 awardee, is the only player to receive the award posthumously; his award was accepted by his wife, Vera.
The Bash Brothers are a duo of former baseball players consisting of Jose Canseco and Mark McGwire.
 Both prolific home run hitters, the two were teammates in Major League Baseball (MLB) for seven seasons with the Oakland Athletics, helping the team win a World Series title in 1989.
 The two began celebrating homers by bashing each other's forearms, which spawned a marketing campaign that was a takeoff on The Blues Brothers.
 After retiring from playing, Canseco and McGwire both admitted to using anabolic steroids during their careers.
Mark David McGwire (born October 1, 1963), nicknamed Big Mac, is an American former professional baseball player and currently a bench coach in Major League Baseball (MLB).
 As a first baseman, his MLB career spanned from 1986 to 2001 while playing for the Oakland Athletics and the St. Louis Cardinals.
 He quickly grabbed media attention in 1987 as a rookie with the Athletics by hitting 33 home runs before the All-Star break, and would lead the major leagues in home runs that year with 49, setting the single-season rookie record.
 He appeared in six straight All-Star Games from 1987 to 1992 despite a brief career decline related to injuries.
 Another string of six consecutive All-Star appearances followed from 1995 to 2001.
 Each season from 1996 to 1999, he again led the major leagues in home runs.
The Wilson Defensive Player of the Year Award is awarded annually to the best defensive player at each fielding position in Major League Baseball.
 One overall Defensive Player of the Year is also selected each year.
 Unlike the Rawlings Gold Glove Awards, which are voted on by major league managers and coaches, the Wilson Defensive Player of the Year Award winners are determined by statistics using sabermetrics.
 In 2012, the baseball glove manufacturer Wilson created the Defensive Player of the Year Award to honor the best defensive player on each team in Major League Baseball.
 One award winner was selected from each league as that league's overall Defensive Player of the Year.
 Starting in 2014, the awards are given to the best defensive player at each position, regardless of league, and the overall award is given to only one player, regardless of league.
 Also in 2014, a new award was created for the best Defensive Team of the Year, regardless of league.
Ryan Matthew Jones (born November 5, 1974) is an American former professional baseball player who spent 14 seasons in minor league baseball and the independent baseball leagues.
 He hit over 200 professional home runs in his career.
 Once considered a potential 30 home run hitter at the major league level, he peaked briefly at Triple-A but never reached the big leagues.
 He had been compared to Mark McGwire.
The 1998 Major League Baseball home run chase in Major League Baseball was the race between first baseman Mark McGwire of the St. Louis Cardinals and right fielder Sammy Sosa of the Chicago Cubs that resulted in both players breaking Roger Maris's long-standing and highly coveted record of 61 home runs.
 McGwire broke Maris's record on September 8 against the Cubs and finished with 70 home runs.
 Sosa finished with 66.
The Marvin Miller Man of the Year Award is given annually to a Major League Baseball (MLB) player "whose on-field performance and contributions to his community inspire others to higher levels of achievement."
 The award was created by the Major League Baseball Players' Association (MLBPA) and was presented to the inaugural winner—Mark McGwire—in 1997 as the "Man of the Year Award".
 Three years later, it was renamed in honor of Marvin Miller, the first executive director of the MLBPA.
 The award forms part of the Players Choice Awards.
The Oakland Athletics' 1987 season involved the A's finishing 3rd in the American League West with a record of 81 wins and 81 losses.
 Mark McGwire set a rookie record by hitting 49 home runs.
 At the beginning of the season, the word "Athletics" returned, in script lettering, to the front of the team's jerseys.
 Former A's owner, Charles O. Finley banned the word "Athletics" from the club's name in the past because he felt that name was too closely associated with former Philadelphia Athletics owner Connie Mack.
 In his first full Major League season, Mark McGwire hit 49 home runs, a single-season record for a rookie; he was named the American League Rookie of the Year.
 McGwire would be the first American League rookie since Al Rosen of the Cleveland Indians in 1950 to lead the American League in home runs.
 The 1987 season also saw the return of Reggie Jackson to Oakland.
The St. Louis Cardinals, a professional baseball franchise based in St. Louis, Missouri, compete in the National League (NL) of Major League Baseball (MLB).
 Brewing magnate Gussie Busch's 37-year-long ownership of the club ended with his death in 1989, and his brewery, Anheuser-Busch (AB) took over.
 In 1995, an investment group led by Drew Baur and William DeWitt, Jr., purchased the team and have owned the club since.
 Shortstop Ozzie Smith – nicknamed "The Wizard" – collected a staggering array of defensive records and awards while performing acrobatic spectacles such as somersaults and flips that mesmerized Cardinal and non-Cardinal fans alike.
 In 1998, Mark McGwire and the Chicago Cubs' Sammy Sosa collocated national attention with their chase of Roger Maris' single-season home run record of 61.
 In addition, McGwire also set numerous team home run records.
 For the 1990s, the Cardinals captured one division title and finished above .500 five times for a .488 winning percentage
