Cain threw a bullpen Saturday afternoon and it was cut short after fewer than 20 pitches, per CSN Bay Area’s Andrew Baggarly. Cain has been day-to-day since leaving Wednesday’s start against the Rockies in the third inning with a mildly strained right hamstring.
While the Giants hope Cain will be ready by Monday, they may have Tim Hudson start again after only throwing 64 pitches against the Rockies on Thursday. Otherwise, the Giants could call on Yusmeiro Petit to make a spot start.
The 29-year-old Cain has a 3.66 ERA and a 39/17 K/BB ratio in 46 2/3 innings over eight starts on the season.
