Will a balky bone in his left foot hold up or will it fail Estes as it did twice last year?
"He looks like he's throwing well," manager Bruce Bochy said yesterday. Health concerns are the main reason Estes, the rotation's only left-hander, cost less than other free-agent pitchers of his stripe, General Manager Kevin Towers said.
"A lot of it is probably the ankle," Towers said of Estes. "It probably scared some people off."
"I want to minimize my pitches per inning," Estes said. "I love to get quick outs. I'd love to throw 27 pitches per game. That would be ideal."
Good luck with that.
