From Tony Jackson:
Takashi Saito does not have a tear in his left hamstring, which tightened up on him in the ninth inning and forced him out of the game. But he won't know anything more than that until today, so it isn't clear how much time he will miss. Grady hinted, in that typically Grady way, that Jonathan Broxton will close in Saito's absence if there is an absence. More on this issue tomorrow.
And from Diamond Leung:
Takashi Saito left the game during the ninth with tightness in his left hamstring. Saito said he did not suffer a tear, and it is unknown how much time he might miss, though it does not for now seem serious. Jonathan Broxton would close games if Saito were unavialable.
