TORONTO -- Matt Cain did not make San Francisco's trip to Toronto for a two-game set with the Blue Jays, manager Bruce Bochy revealed Wednesday.
Bochy did not want to run the risk of unexpected travel delays out of Canada after Wednesday night's game to potentially disrupt his ace's routine for Thursday's start in Colorado. The Giants could have flown Cain out early, which is not exactly uncommon, but elected to leave him behind in San Francisco.
"What didn't make sense is to bring him up here for two days," Bochy said. "We told him to [stay behind]."
Cain threw a bullpen in San Francisco on Sunday and has been working out on his own to prepare for Thursday's start, which is the first of a four-game set against the division rival.
The 28-year-old Cain carries a 2-2 record and 5.04 ERA into the outing, but has won his last two games -- both quality starts -- allowing just three runs over 15 1/3 innings during that stretch.
