Torres strains left groin against Nationals

WASHINGTON -- Giants outfielder Andres Torres left Friday's game early with a left groin strain, and there's a chance he could miss the rest of the series.

Manager Bruce Bochy pinch-hit for Torres in the fifth inning in Friday's 8-1 loss to Washington and said Torres will be checked out again Saturday. Torres could miss the final two games of the series, which would give him two days off plus the All-Star break to let the groin heal.

"It might be a couple days," Bochy said. "We'll hope for better news once we check on him tomorrow. It's going to be questionable."

Torres said he's never dealt with this before and felt the injury occur while running after Roger Bernadina's first-inning double to right-center field. The center fielder said he noticed something right away.

"It started feeling heavy," said Torres. "I hope it's not that bad. It wasn't feeling real well."

Torres led off the game with a home run against Washington starter Stephen Strasburg, but the Giants didn't score again.

Runzler on DL with dislocated kneecap

WASHINGTON -- The Giants placed relief pitcher Dan Runzler on the 15-day disabled list Friday, and he's expected to miss six to eight weeks after dislocating his left kneecap during his first Major League at-bat Thursday in Milwaukee.

Runzler dislocated the kneecap while fouling off a pitch in the seventh inning. His spikes got caught in the clay, and his kneecap popped out. It went back into place, but the left-hander had an MRI Friday in Washington and said no surgery would be needed, with the major ligaments being fine.

"I'm happy there's no surgery required, and now I'm just going to work to get back on the field and do whatever the trainers tell me," Runzler said. "It's happened. It's over now."

The Giants called up right-handed relief pitcher Joe Martinez to replace Runzler. He arrived before Friday's series opener with the Nationals, and manager Bruce Bochy said the team will use Martinez mainly in long relief. But they'll also call on him in other spots.

Bochy said he's glad that Runzler's situation didn't end up worse.

"That's good news that it didn't show any other damage in there," Bochy said. "Still, you feel awful, and it's baseball, but it looks like it's going to be a little while here."

In addition, Runzler couldn't finish the at-bat and had to leave with a 1-2 count. Fellow pitcher Madison Bumgarner came on and struck out, but Runzler was credited with the at-bat.

Ray off to strong start with Giants

WASHINGTON -- Chris Ray has gotten off to a good start with the Giants since they acquired him from the Rangers on July 1.

The right-hander has given the San Francisco bullpen a boost. He's thrown 5 1/3 scoreless innings with the Giants and retired 15 of the 16 batters he's faced.

"I feel good here," Ray said. "I'm getting an opportunity to pitch often, which I like. So far, things have been working out."

This is Ray's first full season back since having Tommy John elbow surgery late in the 2007 season while with Baltimore. Ray went 0-4 last year with a 7.27 ERA, often having problems. The Orioles traded him to the Rangers in the offseason.

But Ray has a 2-0 record with a 2.92 ERA in 39 games this season with the Giants and the Rangers and is pitching like he did earlier in his career.

"I feel great out there," Ray said. "I don't have to think about mechanics. I don't think about anything."

Giants expect Uribe back Saturday

WASHINGTON -- Giants manager Bruce Bochy held infielder Juan Uribe out of Friday's starting lineup for the fourth straight game due to problems with a sprained joint in his left ring finger.

But Bochy said he's looking to see Uribe back in the lineup in the second game of the series.

"He's probably going to go Saturday," Bochy said.

Bochy said another round of hitting and another day of rest should be helpful for Uribe, who had been struggling before sitting out. He hurt his finger about two weeks ago sliding into a base, and while X-rays showed no break, Uribe was just 1-for-27 before sitting out.

Giants geared up for Strasburg

WASHINGTON -- The Giants have fared quite nicely against some of the National League's tougher pitchers, and they were looking forward to facing Stephen Strasburg on Friday.

San Francisco has beaten Ubaldo Jimenez, Roy Halladay and Roy Oswalt already this season.

"I'm eager to see him," said manager Bruce Bochy. "He's quite a talent, and we'll get to see him firsthand ... and hopefully you look forward to the challenge."

The Giants responded well to the challenge early as Andres Torres led off the game with a home run for a quick 1-0 lead.
