SAN FRANCISCO -- There were times, Mark DeRosa said Monday, when he thought his latest wrist injury would end his career. That's part of the reason why his first rehab games with Class A Advanced San Jose were so encouraging to the 36-year-old utility man.

DeRosa went 2-for-5 with a double in two five-inning appearances for the San Jose Giants, playing third base in Saturday's game and second on Sunday, and he will move on to play with Triple-A Fresno starting Tuesday. DeRosa smiled as he said he was "pleasantly surprised" with how he felt, and with a postive mindset aided by his outings this weekend, he could speak optimistically about his future.

"I'm not thinking about it. That was the biggest thing for me -- not worrying about it and going in there and just concentrating on finding timing, finding a rhythm, getting back out there, playing and knowing that I don't have some frayed tendon in my wrist ready to go," DeRosa said. "I think it was a little bit more of a relief this time to get out there. And just the way I felt, to be honest with you. I haven't had an at-bat in a long time. I didn't feel that bad."

However, DeRosa is still cautious about his recovery from a left wrist strain, having had two surgeries on it since October 2009. He didn't know about the timeframe for his potential return, though the initial goal was Aug. 1. And he isn't going to get carried away about how good he feels quite yet, taking his time and listening to the training staff instead of rushing back to action.

"I think I've got to be honest with myself," DeRosa said. "I wanted to come back so bad last time, and I ended up not playing well and doing more damage. I think if I'm going to give this thing a legitimate shot and try to come help this team, I think I've got to listen to them, whenever that may be. If it was up to me, I'd be activated today, but I understand.

"There's opportunities for me to be out there. That being said, I haven't done anything meaningful for this organization in two years, so I've got some work to do," he continued. "I'm very motivated. There were moments where I thought I was done, so just to be able to go there for the last two days and see some positive was good."

Tejada, Stewart dinged up vs. Dodgers

SAN FRANCISCO -- Giants shortstop Miguel Tejada left Monday night's 5-0 win over the Dodgers in AT&T Park during the third inning due to a lower abdominal strain, and catcher Chris Stewart exited in the sixth with a contusion on his head.

Neither injury is serious, Giants manager Bruce Bochy said after the game, and Stewart said he felt fine and probably could have remained in the game. Tejada, meanwhile, could be ready to return in a day or so, Bochy said.

With two outs and a runner on first after right-hander Ryan Vogelsong walked pitcher Chad Billingsley, Dodgers leadoff batter Rafael Furcal knocked a grounder at Tejada. The shortstop muffed the play and earned his team-high 10th error of the season, allowing Furcal to reach safely and Billingsley to advance to second. Tejada came up limping on the play.

A team athletic trainer came out to check on Tejada, eventually helping him as he limped off the field. Rookie shortstop Brandon Crawford entered the game to replace Tejada, and Vogelsong got out of the inning by striking out Aaron Miles.

When Miles singled to right-center field in the sixth, he brought his bat around and knocked Stewart near the top of his head. The catcher remained in the rest of the inning after spending a few minutes sitting on the ground near home plate, but he was replaced in the bottom of the inning by Eli Whiteside.

Stewart passed several tests after the game. He said he would undergo further testing late Monday night and Tuesday afternoon, but he felt ready to go.

"It's one of those things where we're just taking a precautionary route," Stewart said. "If something were to happen like that a second time during the game, who knows how long it would have knocked me out for. It's just a day-to-day thing right now. I feel great."

Bochy mentioned before Monday's game how impressed he had been with Tejada's at-bats lately -- the main reason the veteran started against Billingsley instead of the left-handed-hitting Crawford.

Tejada is batting .341 (14-for-41) with two doubles, two home runs and six RBIs in 12 games this month. After batting .217 over the first two months of the season, Tejada has hit .286 with seven doubles, three homers and 10 RBIs since June 1.

Giants set for visit to White House

SAN FRANCISCO -- The Giants will finally get a chance to meet President Barack Obama and once again celebrate their 2010 World Series championship at the White House next Monday.

The president will welcome the defending champs to the White House to honor them for winning last year's World Series, while also recognizing them for giving back to their community, as part of his tradition of honoring championship teams for their work on and off the field.

The Giants are off Monday, so manager Bruce Bochy said the team will have a little more time to enjoy the nation's capital before heading to Philadelphia for a rematch of last year's National League Championship Series against the Phillies.

"It's going to be very special for all of us. It means you won the World Series the year before, and that's part of the deal that goes with it. It's an honor, and I'm certainly looking forward to it," Bochy said. "The guys can spend some time there and just get a chance to meet the president, which is always an honor. I know the guys have been to the White House, but we haven't been there when the president's been there, so it's going to be a thrill for everybody."

Bochy said he and his players haven't received any guidelines or instructions regarding how to behave around the president or while at the White House, but he wasn't worried about any of his so-called "misfits" acting out of line.

"They're well-behaved," Bochy said. "They may not look it, but they are."

That includes bearded closer Brian Wilson, who drew some attention during the All-Star break for his fashion choice at another public event: the spandex tuxedo he donned at Wednesday night's ESPY Awards in Los Angeles.

"He may break it out for that," Bochy said. "I don't know if they'll let him in wearing that."

Lefty Sanchez has rocky first rehab start

SAN FRANCISCO -- Left-hander Jonathan Sanchez made his first rehab start Sunday with Class A Advanced San Jose, and his numbers weren't impressive.

Recovering from left biceps tendinitis, Sanchez gave up six runs on six hits and two walks while striking out three in just 2 2/3 innings. He threw 51 pitches, 35 of them for strikes. While Giants manager Bruce Bochy admitted Sanchez's line Sunday left something to be desired, he said there was more to the story than just that.

"Overall, the numbers didn't look good," Bochy said, "but he threw better than that, from our reports."

Sanchez will make another start Friday, this time with Triple-A Fresno, and Bochy said he expects the left-hander to pitch better in that outing.

As for how the rotation will be affected upon Sanchez's return, Bochy once again said the Giants will cross that bridge when they come to it.

A question of more immediate concern regarding the starting rotation is who will start Friday's game. Bochy didn't have an answer to that either, as of Monday afternoon. He planned to discuss the matter again with pitching coach Dave Righetti. Barry Zito is scheduled to start the series opener against the Brewers, but given the lefty's struggles in his last outing and Thursday's day off, Matt Cain could get the start on normal rest.

Worth noting

• An interesting -- and perhaps surprising -- stat presented to Bochy before Monday's game: The Giants have been one game better without injured catcher Buster Posey (28-20) than they were with him (27-21). While there are no doubts about how much losing Posey for the year has hurt San Francisco's offensive production, Bochy said it may have also sparked something in the rest of the club.

"More than anything, just doing some little things to help win ballgames. It certainly hasn't been our offense, if you look at the numbers -- power, driving in runs, things like that," Bochy said. "We miss Buster hitting in the heart of our order, but the guys are doing some small things to help win ballgames. And they're not dwelling on the fact that he's not here. That's so important when things like that happen."

• San Francisco's bullpen has allowed just one run in 18 1/3 innings (0.49 ERA) since the All-Star break. The Giants relief corps ranks third in the National League in ERA (2.97) on the season, leads the league in wins (22) and saves (35) and owns the second-lowest batting average against (.221).

• NFL legend Joe Montana, actor Benjamin Bratt and San Jose Sharks coach Todd McLellan were on hand for Monday's series opener against the Dodgers. Montana spoke with Bochy in his office, while Bratt met with several players in the home dugout at AT&T Park.
