In 2002, Zito became one of the best pitchers in baseball. On May 8, Zito signed a 4-year, $9.3 million contract extension, keeping him in Oakland through at least the 2005 season, with a club option for the 2006 season.<ref>{{cite web |title=A'S NOTEBOOK / Zito signs four-year contract extension |url=https://www.sfgate.com/sports/article/A-S-NOTEBOOK-Zito-signs-four-year-contract-2840458.php |website=[[sfgate.com]] |publisher=[[SFGate]] |access-date=May 14, 2023 |language=en}}</ref> On June 22, Zito won his 10th game of the season. It was the earliest that an A's pitcher had reached the 10-win mark since [[Bob Welch (baseball)|Bob Welch]] got there on June 15, 1990. Zito was named to the [[Major League Baseball All-Star Game|All-Star team]] for the first time in his career. On July 18, he went {{frac|7|1|3}} innings while giving up no runs against the Angels. That win gave Zito a team-record 16th straight win at home. Zito again faced the Angels in his next start and produced similar results. He went {{frac|6|1|3}} innings and gave up just one run. That win gave Zito the most wins by an AL pitcher (14). Zito would become the AL's first 15-game winner when he beat the Rangers. On August 23, Zito recorded his 18th win of the season, giving him one more than his previous career-high of 17, in a game against the [[Detroit Tigers]].<ref name="MLB"/>

On August 28, Zito earned his 19th win of the season against the [[Kansas City Royals]]. However, he lost his bid for a [[Perfect game (baseball)|perfect game]] in the sixth inning when [[Neifi Pérez]] singled with one out. Zito gave credit to Pérez. "I wasn't pitching to maintain a no-hitter or something", Zito said. "I left the ball up over the middle to Pérez, and he hit it up the middle. It was a good piece of hitting."<ref>{{cite web |last=Eskew |first=Alan |url=http://oakland.athletics.mlb.com/news/article.jsp?ymd=20020829&content_id=115429&vkey=news_oak&fext=.jsp&c_id=oak |archive-url=https://web.archive.org/web/20131023055459/http://oakland.athletics.mlb.com/news/article.jsp?ymd=20020829&content_id=115429&vkey=news_oak&fext=.jsp&c_id=oak |url-status=dead |archive-date=October 23, 2013 |title=Zito wins 19th, A's win 15th straight |work=[[MLB.com|Athletics.MLB.com]] |date=August 29, 2002 |access-date=October 22, 2013 }}</ref>

In his last start of the season, Zito went six innings and allowed just a run against the [[Texas Rangers (baseball)|Texas Rangers]]. In his last 10 starts, Zito went 8–0, boosting his chances of winning the AL Cy Young Award. "Barry pitched another gem", said Oakland manager [[Art Howe]].
