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.
Zito attended the University of California, Santa Barbara, Los Angeles Pierce College, and the University of Southern California. Drafted three times while in college, Zito signed with the Athletics when they chose him in the first round of the 1999 MLB draft. A year later, he was in the major leagues, finishing fifth in American League (AL) Rookie of the Year Award. He struggled to begin the 2001 season but improved greatly down the stretch, finishing the year with an 11–1 win–loss record over his final two months. He won 23 games (while only losing five) in 2002 and won the Cy Young Award. His record was only 14–12 in 2003, but he still made the All-Star team for the second year in a row. In 2004, he had his worst season at the time, going 11–11 with a career-high 4.48 earned run average. He became Oakland's Opening Day starter in 2005 and finished fifth in the AL with 171 strikeouts. In 2006, he made the All-Star team and posted a 15–1 record when receiving two or more runs of support.
