Brandon Belt’s meteoric rise through the minor leagues included just 13 games at Triple-A, and evidently that’s all he needed.

After Wednesday’s 2-1 come-from-behind victory over the A’s in their spring finale, the Giants announced that Belt will be the first baseman for Thursday’s season opener in Los Angeles.

“He’s earned this, and it makes us a better club,” manager Bruce Bochy said. “We wanted to break with the best club, and right now we feel that having Brandon on the club makes us that.”

Bochy said Belt, 22, will be the everyday starter at first base despite any ups and downs he might have had, moving incumbent Aubrey Huff to right field. To make room for Belt on the roster, veteran Travis Ishikawa was designated for assignment.

Belt was called into manager Bruce Bochy’s office shortly after the game and said he cried when Bochy told him he had made the club.

“I tried not to be too big of a wuss in there, but it’s hard when you’ve been dreaming of this your whole life,” Belt said. “This is just surreal. I don’t even know what to think right now because it’s so unbelievable.

“It’s going to be a great feeling the first time I run on that field and get an at-bat.”

Belt hit .352 with 23 home runs, 112 RBIs and 22 stolen bases at three minor league stops the past season. He continued to impress this spring, tying for second on the club with three home runs and 13 RBIs.

Bochy said he continually talked to general manager Brian Sabean about the decision the past couple of days, and the brain trust even brought Belt into one of their meetings.

Ishikawa can be claimed off waivers by another team. If he isn’t claimed in the next 10 days, he could still report to Triple-A Fresno.
