• With everything at stake on Wednesday, the Cardinals had an all-hands-on-deck situation with their bullpen. Both Lance Lynn and Joe Kelly were available to pitch in relief, if needed, though the Cards would first turn to Lynn since Kelly is lined up to start a potential Game 7.
If the World Series does extend to a seventh game, Wainwright would be available in relief.
• The one pitcher not likely to be called upon, however, is Shelby Miller, whose near non-usage has put him in a spot where he may not be sharp if he was asked to pitch. Miller, who won 15 games during the regular season, has not appeared in a game since Oct. 4.
"It would have to be a situation where we are pushed in a tight spot," Matheny said, when asked what would prompt Miller to be used. "It's just not fair to him without having much action to this point. He's been exactly what we've needed to this point, and fortunately we haven't needed that long guy. But he's a safety valve for us at the end of the game, and we've had some games that were right there and could go who knows how long. Fortunately, we have a pitcher of his ability waiting in case that happens. The unfortunate side of that, is that he's been sitting."
• After playing Shane Robinson in center field in Game 5, Matheny turned back to Jon Jay for Game 6 at Fenway Park. One of the reasons, Matheny said, was because Jay had a hit off Lackey in Game 2. Allen Craig, the team's designated hitter, returned to the cleanup spot, and Carlos Beltran moved back into second place in the lineup.
