Chicago Cubs outfielder Tyler Colvin scored a run and knocked in another Sunday, but his rookie season likely ended when a sliver of a broken bat punctured his chest. Colvin, one of baseball top power hitting rookies with 20 home runs, is expected to miss the final two weeks of the season. Sam Fuld and Brad Snyder should see more playing time.

It was Welington Castillo's bat that injured Colvin. The Cubs backup catcher should play more now that Geovany Soto will undergo knee surgery Monday. Castillo homered, doubled and knocked in three runs Sunday, after hitting 13 home runs at Triple-A Iowa. He's a better hitter than the Cubs' other catcher, Koyie Hill, so those in deep leagues should take a look.

New York Yankees left-hander Andy Pettitte returned from the disabled list with six innings of three-hit, one-run ball on Sunday in Baltimore. Pettitte, who missed two months with the sore groin, lowered his ERA to 2.81 in 19 starts. He has never completed an American League season with an ERA this low. Trust Pettitte for his remaining starts.
