"I'm not sure. We'll have to see," Girardi said. "The good thing is he hadn't worked a lot up to that point, but we'll have to see how he feels."
Soriano allowed a ninth-inning solo homer to James Loney, giving the Red Sox a 3-1 lead at the time, and then pitched a scoreless 10th after Raul Ibanez's pinch-hit game-tying home run.
The right-hander usually tells Girardi that he is ready to pitch, but he battled something of a dead arm after throwing 32 pitches across both ends of a Sept. 19 doubleheader against the Blue Jays. In four appearances since then, Soriano has a blown save and has allowed three runs -- including two homers -- in 4 1/3 innings (6.23 ERA).
"The curious thing is how he can bounce back from that as we move forward," Girardi said. "We've been in playoff baseball basically for a month, and guys in that room are used to winning, and guys in that room are used to stepping up. That's what he did last night by going two innings for us. Guys are going to want to be out there, and it's our job to make sure that they're OK."
