Matt Cain entered spring training competing with Ty Blach for the fifth starter spot.
On Thursday morning, Giants GM Bobby Evans provided an update on the position battle.
"Blach put up a good spring for himself, and it does make the decision harder," Evans said on KNBR 680. "We'll process it today with the coaching staff and Boch and I, and we'll make a final call."

Back in early February, Evans said: "“In a perfect world, Matt Cain would be Matt Cain and he would take that spot."
Over seven games (six starts) this spring, Cain went 0-1 with a 7.82 ERA.

Cain is making nearly $21 million this season in what is the final guaranteed year of the 6-year, $127.5 million deal he signed in April 2012.
"Again, with the track record that Matt Cain's had overall, it would seem easy," Evans said. "But yet, the last couple years have been so rough and we've had the injuries and the hard contact against him.
"But he did finish strong with the Cubbies (Cubs) and I think it does give him an edge as we close out this decision."
