San Francisco Giants right-hander Johnny Cueto threw a bullpen session Saturday, and the team was encouraged enough for manager Bruce Bochy to say the club hopes Cueto can return toward the end of this season. Cueto, who had major elbow surgery last August, was 18-5 in 2016 and selected to the All-Star game, but has since gone 11-10 in the last two years combined. ''I think he surprised a lot of us with where he's at,'' Bochy said before Saturday's game against the Arizona Diamondbacks.
