Question: Which member of the Oakland Athletics that was lost in the 2007 season was born on May 13, 1978?
Context: 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. Theodore Rodger Kubiak (born May 12, 1942) is a former switch-hitting infielder for the Kansas City Athletics, the Oakland Athletics, the Milwaukee Brewers, the St. Louis Cardinals, the Texas Rangers, and the San Diego Padres.  He was a member of the Oakland Athletics teams that won three World Series in a row (1972–74).  Kubiak still holds the Brewers' record for most RBIs in a single game, seven (later equalled by Jose Hernandez and Richie Sexson), which he set at Boston on July 18, 1970, the team's first year in Milwaukee.  The record is all the more remarkable given that Kubiak was not known for his batting. 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. 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 Oakland Athletics all–time roster is a list of people who have played at least one game for the Oakland Athletics, Kansas City Athletics, or Philadelphia Athletics baseball teams of the American League, along with their primary position and years played for the team.  It does not include players for the 1871–76 Philadelphia Athletics, the 1882–1890 Philadelphia Athletics, or the 1891 Philadelphia Athletics.  The only Athletics player with no regular season appearances is Mark Kiger who only played for Oakland during two games in the 2006 American League Championship Series. William Lamar Beane III (born March 29, 1962) is a former American professional baseball player and current front office executive.  He is the Executive Vice President of Baseball Operations and minority owner of the Oakland Athletics of Major League Baseball (MLB).  Prior to his front office career, he played in MLB as an outfielder between 1984 and 1989 for the New York Mets, Minnesota Twins, Detroit Tigers, and Oakland Athletics.  He joined the Athletics front office as a scout in 1990.  He was named general manager after the 1997 season, and promoted to executive vice president after the 2015 season. 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. Mark Christopher Smith (born November 23, 1955) is a retired Major League Baseball pitcher.  He played during one season at the major league level for the Oakland Athletics.  He was drafted by the Baltimore Orioles in the 9th round of the amateur draft.  He played his first professional season with their Class A-Advanced Miami Orioles in 1978, and his last with the Oakland Athletics in 1983. The 2008 Seattle Mariners season was the 32nd Major League Baseball season in the team's history.  Coming off the heels of the previous 2007 season, in which the M's finished with their first winning record since 2003, the team was widely expected to once again compete for the American League West division championship.  The team was bolstered by some major roster additions during the previous offseason, most notably starting pitchers Érik Bédard and Carlos Silva.  However, by the end of May, it became apparent that the team had gone back to its losing ways of the 2004–06 seasons.  Despite their losing ways, they won their first and last game of the season.  Their longest winning-streak of the season is 4 games after a Cleveland sweep at the end of August and a 12-6 win against the Texas Rangers on the first day of September.  However, standing at 57-87, their longest losing-streak of the season is 12 games, 11 on the road, 1 at home, after being swept by the L.A. Angels, Kansas City Royals, Oakland Athletics, and suffering a loss at the last homestand opener against the L.A. Angels.  On September 23, the Mariners became the first club to spend $100 million in payroll and lose 100 games.  The team finished the season with a 61-101 (.377) record, last in the West for the 4th time in 5 years, and second worst in the Majors. Barry William Zito (born May 13, 1978) is an American former professional baseball pitcher and musician.  He played 15 seasons in Major League Baseball (MLB) for the Oakland Athletics and San Francisco Giants.  His pitching repertoire consisted of a curveball (his strikeout pitch), a four-seam fastball, a two-seam fastball, a circle changeup, and a cutter–slider.
Answer: Barry Zito
