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 Oakland Athletics' 1984 season involved the A's finishing 4th in the American League West with a record of 77 wins and 85 losses.
 While the A's struggled for a third consecutive season, they staged a major coup by drafting future superstar Mark McGwire with the tenth overall pick of the 1984 Major League Baseball Draft.
 The season also marked the end of Rickey Henderson's first (of four) stints with the Athletics.
 His second stint would begin in 1989.
Jarrod Parker (born November 24, 1988) is an American professional baseball pitcher who is a free agent.
 He was drafted by the Arizona Diamondbacks as the 9th overall pick in the 2007 Major League Baseball Draft from Norwell High School in Ossian, Indiana.
 He previously played in Major League Baseball (MLB) for the Diamondbacks and the Oakland Athletics.
Peter John Smith (born February 27, 1966) is a former Major League Baseball starting pitcher, born in Abington, Massachusetts.
 He was drafted by the Philadelphia Phillies in the first round (21st overall pick) in the 1984 Major League Baseball draft.
 Smith was signed on June 14, 1984 to play in the Philadelphia Phillies organization.
 He batted and threw right-handed during his baseball career.
Leonard Shenoff Randle (born February 12, 1949) is a former Major League Baseball player.
 He was the first-round pick of the Washington Senators in the secondary phase of the June 1970 Major League Baseball draft, tenth overall.
Stephen Robert Gajkowski (born December 30, 1969) is a retired Major League Baseball pitcher.
 He played during one season at the major league level for the Seattle Mariners.
 He was drafted by the Cleveland Indians in the 18th round of the 1990 Major League Baseball Draft.
 Gajkowski played his first professional season with their Rookie league Burlington Indians in 1990, and his last season with the Oakland Athletics' Double-A Midland RockHounds and Triple-A Sacramento River Cats in 2000.
Taylor McDowell "Dunc" Duncan (May 12, 1953 in Memphis, Tennessee – January 3, 2004 in Asheville, North Carolina) was an American baseball infielder.
 Duncan, who was a college teammate of Leon Lee in Sacramento, was selected by the Atlanta Braves as the 10th overall pick of the 1971 Major League Baseball Draft.
 A year later he was traded to the Baltimore Orioles and spent five seasons playing for Orioles-affiliated minor league clubs.
 In September 1977 Duncan was claimed off waivers by the St. Louis Cardinals and made his major league debut, playing a handful of the remaining games.
 In the off-season Duncan changed teams again as the Oakland Athletics selected him in the Rule 5 draft.
 The 1978 season was Duncan's last in Major League Baseball: he appeared in 104 games of the 1978 season playing mostly third base.
 Duncan continued to play in the minor leagues until 1980.
 The obituary of The Sacramento Bee quoted a major league scout who believed that Duncan's career had been hampered by a broken ankle he suffered early in his minor league career.
The Oakland Athletics are a Major League Baseball franchise based in Oakland, California.
 They play in the American League West division.
 Also known in their early years as the “Philadelphia Athletics” (1901–54) and “Kansas City Athletics” (1954–67), pitchers for the Athletics have thrown eleven no-hitters in franchise history, five during the Philadelphia years and six after the move to Oakland but none during the Kansas City era.
 A no-hitter is officially recognized by Major League Baseball only “when a pitcher (or pitchers) retires each batter on the opposing team during the entire course of a game, which consists of at least nine innings.”
 No-hitters of less than nine complete innings were previously recognized by the league as official; however, several rule alterations in 1991 changed the rule to its current form.
 A no-hitter is rare enough that one team in Major League Baseball has never had a pitcher accomplish the feat.
 Two perfect games, a special subcategory of no-hitter, have been pitched in Athletics history.
 As defined by Major League Baseball, “in a perfect game, no batter reaches any base during the course of the game.”
 These feats were achieved by Catfish Hunter in 1968, which was the first perfect game in American League history since 1922, and Dallas Braden in 2010, which was the second perfect game in the majors – both against the same team – in ten months.
Raymond Earl Fosse (born April 4, 1947 in Marion, Illinois) is an American former professional baseball player and current television sports color commentator.
 He played in Major League Baseball as a catcher.
 He was drafted in the first round of the 1965 amateur draft by the Cleveland Indians.
 He was the Indians' first ever draft pick, as 1965 was the first year of the Major League Baseball Draft.
 He batted and threw right-handed.
 He has been a television and radio broadcaster for the Oakland Athletics since 1986.
Rob Ryan (born June 24, 1973 in Havre, Montana) is a former outfielder in Major League Baseball who played for the Arizona Diamondbacks and the Oakland Athletics.
 He attended Washington State University where he played college baseball for the Cougars from 1993–1996, and was drafted by the Diamondbacks in the 26th round (785th overall pick) of the 1996 Major League Baseball Draft.
 He signed with the Diamondbacks two days later on June 6.
