That's right, none. If the Orioles come back against the Royals, they'll be the first team to have accomplished it. The Giants are trying to put the Cardinals into the same situation.
Pitching for the Giants will be Jake Peavy, whom they acquired from the Red Sox for two minor leaguers on July 26. His performance before and after the trade has been an interesting contrast:
Adjusted for league and ballpark, his ERA was 18% worse than the AL average with Boston, 61% better than the NL average with San Francisco.
Here's his breakdown against the Cardinals:
|St. Louis Cardinals||3||4||2.97||9||9||57.2||50||24||19||9||18||0||61||1.179|
|St. Louis - Postseason||0||2||10.13||3||3||13.1||25||15||15||3||5||2||9||2.250|
He did look decent against Washington in the Divisional Series opener, giving up no runs in 5.2 innings, though he struck out only three and walked the same number, running his pitch count up to 104 and getting strikes on only 60% of his pitches (the league average was 64%). So I'd disregard his line from those three games against the Cardinals--two from long ago--but at the same time assume a busier evening for the Giants bullpen than last night, when Madison Bumgarner lasted until there were two outs in the eighth.
