UPDATE, 11:53 a.m.: Manager Bruce Bochy just said that outfielder Michael Morse will get the lion’s share of start at first base in Brandon Belt’s place, for now. That decision was made because Morse has played 130 games at the position, including 100 starts, though none since 2002.

Bochy said other options were considered, including Hector Sanchez and Adam Duvall, whose name was discussed “quite a bit.” But Buster Posey as a regular first baseman was not an option.

“We just think this is the best way to go because Morse has played first base. He came up as an infielder,” Bochy said. “He’s pretty good over there. Now, I’m saying that not seeing him first-hand. The reports we got were good. My guess is he’s going to get acclimated pretty quickly over there.”

Morse is not playing first today but might against Clayton Kershaw on Sunday, although Bochy left open the possibility of waiting until Monday so Morse can get some work at first base beforehand. He has not taken grounders since spring training.

Morse was open to the idea

As noted below, Tyler Colvin’s contract was purchased from Fresno and he could get a lot of starts in left field in Morse’s place. Bochy plans to go with the hot hand in left field. While Colvin is a question mark, having spent the whole season in Fresno, neither Gregor Blanco nor Juan Perez has hit this year.

Bochy discussed some side benefits of Morse moving to first: Although his defense at first will not be as good as Belt’s, the Giants will get a better defender in left field. Bochy also will be able to keep Morse in the game’s longer, assuming he takes to the new position.

“This certainly will cut down on his ‘quality starts.’ he won’t go six innings anymore,” Bochy joked.

Sanchez was an option but has only one game of experience at first base, in spring training. I specifically asked Bochy if he consulted with Posey, under the theory that Posey might be the best option because he already plays the position a lot. Bochy said no and suggested that Posey as an everyday first baseman was not considered.

“He’ll still probably go to first base occasionally,” Bochy said. “We’ll keep doing that as we have done that. We can get some of the matchups we want.”

Bochy could not provide more information on Belt’s injury. Belt has not seen the hand specialist in San Francisco yet.

The Giants placed Marco Scutaro on the 60-day disabled list to clear a 40-man spot for Colvin. A no-brainer move. It’s retroactive and he wasn’t going to play before June 1.

ORIGINAL POST: Answer to the last question first: Buster Posey will play first base.

The Giants have purchased the contract of outfielder Tyler Colvin from Triple-A Fresno, where he has been hitting exceptionally well against right-handed pitchers.

The Giants also appear to have optioned reliever George Kontos to Fresno. After manager Bruce Bochy met with a player to be sent out, a new lineup card appeared with Kontos’ name gone from the reliever section.

They activated Matt Cain from the 15-day disabled list and put Brandon Belt on it.

Much more here after we talk to Bochy within the next hour.
