OAKLAND -- After blanking the Yankees for eight innings and limiting them to four hits Sunday, Barry Zito admitted that he didn't sleep well on Saturday night.

"I never sleep well in New York. We know how intense these games are. Even when you're not pitching and not playing, coming out to Yankee Stadium is huge," Zito said. "We get fired up."

His inspired performance, albeit after a "restless" night in which he didn't get his preferred 12 hours of winks, helped propel the A's to a 2-0 win and helped him earn the American League Pepsi Co-Player of the Week award.

Zito quieted the powerful Yankee lineup and outdueled six-time Cy Young Award Winner Roger Clemens in the process. Zito raised his record to 5-2 and lowered his 2003 ERA to 2.20 with his effort.

That performance followed a win against the Chicago White Sox on Tuesday in which he outpitched Bartolo Colon, a 20-game winner last season. Zito limited the Sox to one run over seven innings in a 3-2 A's win.

Six of Zito's seven starts this season have been quality starts. He's allowed more than two earned runs once, and more than one earned run only twice. The left-hander's career record is now 52-19 (.732) in 91 career starts, the best winning percentage in Major League history.

Zito shared the award with Rangers slugger Juan Gonzalez, who tied for the league lead with five homers and a 1.000 slugging percentage during the week collecting 25 total bases.
