The 2017 Oakland Athletics season was the 50th for the Oakland Athletics franchise in Oakland (all at Oakland Coliseum), as well as the 117th in club history.
 The A's began the season on April 3 at home against Los Angeles Angels of Anaheim.
 They will finish the season at the Texas Rangers on October 1.
The Oakland Athletics' 2007 season was their first since 2004 in which they defended a title.
 The A's were without Frank Thomas (Toronto) and ace Barry Zito (San Francisco), both players who the A's lost to free agency.
 They filled the space left by Frank Thomas by signing free agent catcher Mike Piazza to a one-year contract worth $8.5 million to be the team's designated hitter.
 They were also without Ken Macha, their former manager who was fired after 4 seasons with the team and replaced by Bob Geren, as well as third-base coach Ron Washington, who accepted the managerial position of the Texas Rangers.
 It was their first losing season since 1998.
Wilbur Donald Wakamatsu (born February 22, 1963) is an American former professional baseball player, scout, manager and current coach.
 He played as a catcher in Major League Baseball for the Chicago White Sox.
 He was hired as bench coach of the Kansas City Royals for the 2014 season.
 He was the manager of the Seattle Mariners for the season, as well as the majority of the season.
 He was the Toronto Blue Jays' bench coach for 2011 and 2012, after which he was replaced by DeMarlo Hale.
 During the 2013 season he worked as a scout for the New York Yankees in the Dallas/Fort Worth area.
Robert Peter Geren (born September 22, 1961) is a former Major League Baseball catcher and manager.
 During a 5-year playing career, he played for the New York Yankees (1988–1991) and the San Diego Padres (1993).
 He managed the Oakland Athletics from 2007 through 2011 and also coached for the New York Mets.
 He is the current bench coach of the Los Angeles Dodgers.
Stephen Robert Staggs (born May 6, 1951) is a former Major League Baseball second baseman who played for two seasons.
 He played 72 games for the Toronto Blue Jays during the 1977 Toronto Blue Jays season and 47 games for the Oakland Athletics during the 1978 Oakland Athletics season.
The 1978 Oakland Athletics season was the team's eleventh in Oakland, California.
 The team sought to rebound from its first losing season in a decade (a 63-99 result in 1977).
 Despite low expectations, the Athletics remained competitive for nearly three-quarters of the season.
 Despite posting a respectable 61-56 mark through 117 games, the Athletics collapsed in the season's final weeks; their 8-37 finish ensured a second consecutive season of fewer than 70 wins.
Robert Lewis Thomson (born August 16, 1963) is a Canadian bench coach for the New York Yankees.
 He previously served as bench coach during the 2008 season, third base coach from 2009 - 2014, and returned to serving as bench coach in 2015.
 He has also served as Major League Field Coordinator for the organization.
The 2014 Oakland Athletics season was the 46th for the franchise at O.co Coliseum, as well as the 114th in club history.
 The Athletics entered the season hoping to win a third consecutive American League West championship; to that end, the team made a number of key signings and trades during the 2013-14 MLB offseason.
 Notably, Athletics traded outfielder Michael Choice for left fielder Craig Gentry and pitcher Josh Lindblom; they also traded the promising but oft-injured Brett Anderson for reliever Drew Pomeranz.
 Additional trades brought in relievers Fernando Abad (acquired for John Wooten), Luke Gregerson (acquired for Seth Smith), and Jim Johnson (acquired for Jemile Weeks and David Freitas).
 In free agency, the Athletics signed former All-Star starting pitcher Scott Kazmir to a two-year deal.
 These moves, among others, sought to bolster the depth of team's starting pitching and bullpen.
Roger Craig Smithberg (born March 21, 1966) is a former Major League Baseball pitcher who played for two seasons.
 He pitched for the Oakland Athletics for 13 games during the 1993 Oakland Athletics season and two games during the 1994 Oakland Athletics season.
The 1980 Oakland Athletics season was the team's thirteenth season in Oakland.
 The A's, under first-year manager Billy Martin, began the season with low expectations following their insipid 1979 campaign.
 Strong performances from pitchers Mike Norris, Matt Keough, and Rick Langford, along with the brilliant play of breakout star (and future Hall-of-Famer) Rickey Henderson, paved the way for a staggering 29-win increase over the previous year's output.
 The Athletics, only one year removed from baseball's worst record, swung to a second-place finish behind their 83-79 record.
