A look at what's happening around the major leagues today:
___
MIDWAY MATCHUP
The Cardinals and Cubs continue a three-game series at Wrigley Field after Chicago took the opener Friday. Starlin Castro homered twice and tied his career high with six RBIs in that one. The middle infielder has been outstanding at the plate of late, hitting .417 with power over his last 11 games. St. Louis will try to stave off the hard-charging Cubbies with ace Michael Wacha (16-5, 2.96 ERA). The Cardinals hope to get back slugger Matt Holliday, who exited Friday after being hit in the head by a fastball from Dan Haren.
