That streak came to an end in the fourth inning, when Yadier Molina led off with a single. David Freese followed with a walk and then Jon Jay with another single, but third base coach Jose Oquendo opted to hold Molina at third on Jay's single:
The hold was understandable since Molina is rather slow and there were no outs in the inning. It also ultimately helped save Peavy a run.
The Kozma at-bat was the biggest since it's unrealistic to ask the pitcher (Kelly) to do something productive at the plate. An argument could be made that manager Mike Matheny should have pinch-hit Allen Craig for Kozma and used Daniel Descalso at short for the remainder of the game. Kelly was pitching well enough to remain in the game.
When the bases were loaded with no outs, the Red Sox had a 10.2 percent chance of winning. After the third out, they had a 23.1 percent chance to win. That's a pretty big swing.
The Red Sox scored a run in the next half inning to cut the Cardinals' lead to 2-1.
