Belt finding success quickly at Triple-A

SAN FRANCISCO -- When the Giants assigned top prospect Brandon Belt to Triple-A Fresno on Wednesday, they probably didn't expect such quick results.

Belt showed the Giants, who asked him to refine his hitting approach, in his first at-bat that he's listening. Belt hit a two-run shot against Reno Aces starter Micah Owings, who has also played in the Major Leagues, giving the Grizzlies their only runs in a 9-2 loss Saturday night.

Belt's shot landed in the parking lot beyond the right-field wall. He also drew a walk and struck out once in the contest.

Belt was in left field again Sunday and hit an RBI double in his first at-bat.

Feeling great, Ross starts to contribute

SAN FRANCISCO -- Cody Ross wasn't worried about his lack of production two games into his return from rehabbing a calf injury he suffered in Spring Training.

It was still rewarding to be back on the field, though, and getting his first two hits of the season was icing on the cake.

"You feel like you're part of the team again," Ross said before the Giants' series finale against the Atlanta Braves on Sunday. "When you're on the DL, you don't feel like you're a part of it. You're just a cheerleader."

Ross was 2-for-4 and drove in a run in Saturday's 5-2 loss to the Braves. He also threw out Eric Hinske trying to stretch a hit down the right-field line into a double.

"It wasn't quite enough yesterday but it was nice to contribute," said Ross, who was in the No. 7 spot in the order Sunday against Braves right-hander Brandon Beachy. "A long time ago I used to worry about things, but if you panic after the first two games, you're only putting too much pressure on yourself."

Ross, the Most Valuable Player of last year's National League Championship Series, was enjoying a solid spring, hitting .295 in the Cactus League with a .591 slugging percentage, when he left the March 23 game against the Angels in the first inning with a strained right calf muscle.

"It's always nice to get the first hit out of the way," said Ross. "But I wasn't going to worry about anything. I feel great."

DeRosa eager to get more playing time

SAN FRANCISCO -- Mark DeRosa was limited to 26 games last season when it was learned that 2009 surgery to repair a torn tendon sheath in his wrist failed and he spent most of 2010 on the disabled list.

Originally signed to be a full-time player, DeRosa has appeared in half of the Giants' first 20 games this season and has 17 at-bats.

"I look forward to getting in there," DeRosa said Sunday. "When I do start playing, I want to be right. I want to be able to show up and play instead of spending an hour getting treatment every day."

DeRosa can play multiple positions -- he's played six different positions, including all four infield spots -- and has hit in every spot of the order. His versatility is a blessing and a curse on a team where manager Bruce Bochy has enough trouble trying to find spots for several players.

His practice time has been affected by his health but he's ready to play any time.

"If I were starting today, I'd be in the batting cages instead of in here," DeRosa said from in front of his locker. "I follow a routine for when I start and when I don't. I'll get my hitting in; I'll get my lift in. For now I have to listen to my body. If I feel good, I can get extra work."

Vogelsong's status depends on Sanchez's health

SAN FRANCISCO -- Giants manager Bruce Bochy said he would watch starter Jonathan Sanchez for signs of fatigue during his Sunday start. The left-hander battled an illness the past couple of days and needed an IV on Saturday.

"It slowed him down but he's bouncing around pretty good," Bochy said. "We do need to watch him because it probably sapped some of his strength."

Bochy said with Monday's day off, everybody in the bullpen would be available. That includes Ryan Vogelsong, who is slated to join the rotation at some point in the near future.

"He's eventually going to get into a routine to make three starts," Bochy said. "If he pitches an inning, he'll need at least two days to make a start. If he pitches more than an inning, he'll need at least three days."

Bochy has yet to announce a rotation beyond Matt Cain's scheduled start in Pittsburgh on Tuesday.
