Brandon Moss homered twice and Drew Pomeranz and three relievers combined on a four-hit shutout as the Oakland Athletics beat the Chicago White Sox 9-0 for their sixth consecutive win.
Josh Reddick also homered while Yoenis Cespedes added two hits and scored twice to anchor a shuffled Oakland lineup that had catcher John Jaso batting leadoff for just the fourth time this season.
Pomeranz (3-1) went five shutout innings in his first start on May 7 and matched that with another stellar five-inning outing against Chicago.
The Athletics' left-hander struck out a career-high eight, walked two and gave up just three single hits.
The White Sox are struggling in the early-season, having lost their fourth straight match.
Cardinals down Cubs
Pinch-hitter Greg Garcia was hit by a pitch with the bases loaded and one out in the 12th inning, sending the St. Louis Cardinals over the Chicago Cubs 4-3..
Jhonny Peralta led off the 12th with a single for his third hit. Justin Grimm (1-2) retired Matt Holliday on a popup, but walks to Allen Craig and Yadier Molina loaded the bases for Garcia.
Seth Maness (1-2) tossed a scoreless 12th for the win. Both teams used seven pitchers.
Trailing 3-2 going into the ninth, Chicago rallied to tie it off closer Trevor Rosenthal on Emilio Bonifacio's RBI single with two outs.
