DENVER -- The Giants optioned Brandon Belt to Triple-A Fresno with instructions for the first baseman to refine his hitting technique.
Belt, who turned 23 on Wednesday, was dropped from the active Major League roster to accommodate outfielder Cody Ross, who officially left the 15-day disabled list. Ross started in right field and batted fifth in Wednesday's series finale against the Colorado Rockies.
Belt entered Spring Training with the same sort of hype that accompanied 2010 Rookie of the Year Buster Posey's ascent to the Majors. Belt made the Opening Day lineup at first base after hitting .282 in 28 exhibition games, with three home runs and 13 RBIs -- which tied him for second on the team. But consistency eluded the 6-foot-5 Texan, who hit .192 in 17 games with the Giants.
Belt said that he examined videos of himself and realized that a "timing issue" has been causing him to dip the barrel of the bat ever so slightly when he swings.
"I'm fouling balls off, even if I'm getting to them in time," he said. "I'm confident I can fix it pretty soon."
Belt relished his stint with the Giants, short as it was.
"Even though it didn't go the way I wanted, it still was a lot of fun," Belt said. "It gave me an idea of what to expect when I get back here. And hopefully, I'll be back up here sooner than later."
