Ryan, who is hitting .289 in his first full season as the Cardinals' shortstop, jammed his finger diving back into first base on a pickoff attempt in the sixth inning of the Cardinals' 11-6 win at Busch Stadium on Monday night.
"I was kind of in between steps and I landed on my pinky," Ryan said. "Batting wouldn't be the most comfortable thing."
The right-handed-hitting Ryan had his pinky finger taped to his ring finger on Tuesday and said while he was available to play defense or pinch-run, hitting wasn't an option on Tuesday night. He probably won't be available to hit again on Wednesday afternoon in the series finale but said he hoped to be ready to go this weekend after the off-day on Thursday.
Ryan stayed in the game and was in the on-deck circle in the bottom of the eighth when catcher Jason LaRue ended the inning. Had Ryan been forced to bat, he wouldn't have taken the bat off of his shoulders.
"I was left on deck, which was ... I was glad," Ryan said. "That was the plan, I was going to take. I knew it was going to be bad.
"It's going to be uncomfortable batting. I can play, but I'm not going to be 100 percent."
