Worth noting

• Right-hander Keith Butler, a member of the 40-man roster, underwent season-ending Tommy John surgery on Wednesday. Butler had to stop pitching in Triple-A earlier this month due to discomfort in his right elbow, and it was later confirmed that he had a tear of the ulnar collateral ligament. The typical recovery time for this procedure is 12 to 18 months.

• Giants right-hander Matt Cain threw a bullpen session on Wednesday and remains on track to rejoin San Francisco's rotation during the Giants' upcoming visit to St. Louis. Cain is scheduled to pitch on Saturday against righty Michael Wacha. Cain exited his previous start with a strained right hamstring.

• The Yankees have been the first team to employ an exaggerated infield defensive shift on Matt Carpenter this season. Carpenter has not typically been a pull-happy left-handed hitter, but he has grounded balls to the right side with more frequency this season.

"You can't ride one team too much when they do that, because you can't replicate their pitching staff with their pitching staff's stuff and then how they're individually going to pitch a particular hitter," Matheny said.

Carpenter entered Wednesday with a nine-game hitting streak, tied for the longest active such streak in the NL.

• According to the Elias Sports Bureau, Lance Lynn became the first Cardinals pitcher since 1994 to have more strikeouts at the plate (four) than he did of his opponent (two) in a shutout. The last was Bob Tewksbury, who struck out one batter while striking out twice himself in a shutout of the Braves.
