Worth noting

• Carpenter, who singled and scored in the first inning on Saturday, has now scored a run in all 13 games in which he has gotten a hit. Carpenter entered the day tied with Colorado's Carlos Gonzalez for the National League lead in runs scored with 20.

• By stranding another pair of runners on Friday, lefty Randy Choate has now allowed only two of 15 inherited runners to score. No pitcher in baseball has inherited more baserunners this year than Choate, who signed with the club last offseason.

• The Cardinals will not have to worry about facing Pirates second baseman Neil Walker the rest of this series, as Walker had to receive six stitches on his right index finger knuckle after Pete Kozma's cleat came down on his hand in the eighth inning on Friday. The injury occurred when Walker was sliding into second base trying to break up a double play.

"When he went up, he didn't fall down; he tried to catch himself with his cleat," Walker said of Kozma. "My right hand got on the ground and he got me on my knuckle. I got six stitches in my knuckle. No tendons or issues like that. I'm going to have to give it a few days of no moving it."

• Prospects Oscar Taveras and Kolten Wong each had two hits in Triple-A Memphis' loss on Friday. The 2-1 loss to Nashville ended on a walk-off balk by Memphis reliever Jorge Rondon.
