Uehara seems comfortable getting four outs, but not more.
From Sunday's Glob:
"Some 20 minutes after the win, which lifted the Sox to a 2-0 lead in the best-of-five American League Division Series, a pensive-looking Uehara teased a laugh out of a group of Japanese-speaking journalists in the Red Sox clubhouse. Later, through a translator, the vivacious righthander explained that the Asian reporters suggested that he could have pitched the seventh, eighth, and ninth innings, an unheard-of workload in today’s game of bullpen artistes.
“I told them not the seventh,’’ a smiling Uehara said flatly, which was what summoned the laugh.
To which an English-speaking reporter then asked if that meant he was up to taking the ball for the eighth and ninth. And with head tilted ever so slightly, and grin breaking out, the Mighty Koji said, “Four outs.’’
