ST. LOUIS – A rainout gave Trevor Rosenthal some time to contemplate his first blown save of the year.
"Pitching behind in the count, that's what hurt me," Rosenthal said after the Cardinals won 4-3 in 12 innings Tuesday night. "Everybody goes through it.
"Keep going out there and working on it and try to get better."
The game between the Chicago Cubs and Cardinals scheduled for Wednesday night was rained out. It was postponed before it started because of a wet weather forecast. They'll make up the game as part of a day-night doubleheader at Busch Stadium on Aug. 30.
Michael Wacha (2-3) and the Cubs' Jason Hammel (4-1), the scheduled starters for Wednesday, will now go Thursday.
Rosenthal had been 10 for 10 before giving up the tying single to the Cubs' Emilio Bonifacio in the ninth inning Tuesday night. A walk to Darwin Barney contributed to Chicago's rally and the Cardinals won 4-3 in 12 innings.
"He's going to have to cut down on giving free bases in the ninth inning," manager Mike Matheny said. "Bad things can happen. You have to figure out a way to use your defense if nothing else."
The Cubs are 3-15 in games decided by two runs or fewer.
"I'm more concerned if we didn't fight back," manager Rick Renteria said. "The reality is we took the lead and they ended up going ahead on us, but we came back.
"I think the fact that we keep bouncing back is something."
