Benches clear in second inning of Wednesday's finale

SAN FRANCISCO -- Jesus Guzman admitted to being very upset Wednesday when Giants pitcher Madison Bumgarner threw a pitch behind him in the second inning at AT&T Park.

But by the end of the game, and after he hit a home run off Bumgarner in the seventh inning, the Padres first baseman said he was ready to move on.

"It's part of the game," Guzman said. "I will forget it."

The Giants defeated the Padres, 4-2.

There was an implication that the Giants were upset that Guzman showed emotion a day earlier after he hit a pinch-hit, two-run home run in the eighth inning in a game the Giants eventually won.

"I was enjoying the home run with my teammates," Guzman said. "I wasn't trying to be disrespectful of their team."

San Diego manager Bud Black didn't understand why Bumgarner fired a pitch -- the first pitch of the at-bat -- behind Guzman.

"I have no idea where that came from," Black said. "That was uncalled for, I thought. I didn't get it."

And if Bumgarner opted to throw behind Guzman because the Giants didn't like how he celebrated after his home run?

"If it was … Bumgarner shouldn't have done it," Black said. "Guzman was showing emotion like so many other players in our game do. He was emotional. It was a key part of the game in a key series."

Bumgarner declined to comment on the pitch to Guzman and the ensuing bench-clearing incident.

"There's no need to comment on that. No need to," he said.

Guzman took a couple steps toward the mound and also pointed the bat toward Bumgarner while also yelling in his direction. San Francisco catcher Buster Posey intervened, standing between Guzman and Bumgarner.

"We were just trying to get inside to a guy that's hurt us over the plate before," Posey said.

The benches cleared but the two teams dispersed quickly with no ejections issued. Play resumed in fewer than five minutes.

Warnings were issued to both sides.

"These things happen. They're part of baseball," said Giants manager Bruce Bochy.

Padres lose Cabrera to DL with hamstring strain

SAN FRANCISCO -- The Padres have officially lost one of the most dynamic players in the National League this season to the disabled list.

The Padres placed shortstop Everth Cabrera on the 15-day disabled list Wednesday with a mild strain of his left hamstring.

"It's tough, but it's probably good," Cabrera said. "For me, at this point, it's probably better to lose 12, 13 games than any more. We'll shut it down so it gets better and I can get back to playing."

The team recalled outfielder Jaff Decker from Triple-A Tucson. He was in uniform for Wednesday's series finale against the Giants.

Cabrera leads the team in runs (37) and hits (84), is tied for the Major League lead in stolen bases (31) and has a .305 average and a .382 on-base percentage while playing a demanding position well.

Cabrera suffered the injury trying to steal second base in the eighth inning Sunday. His disabled list stint will be backdated, but the Padres now know for certain they'll be without Cabrera for a while.

"We wanted to give it a few days to see if it would resolve itself," said Padres manager Bud Black of Cabrera's hamstring. "We want to give it the best opportunity to heal. The legs are a big part of Cabby's game. We just felt we couldn't risk him coming back too soon."

The Padres have used newcomer Pedro Ciriaco and Alexi Amarista at shortstop already in the absence of Cabrera. Logan Forsythe, who is filling in at second base for an injured Jedd Gyorko (right groin strain), is another option at shortstop. Amarista struggled defensively in Tuesday's 5-4 loss to the Giants.

The Padres have four position players from their Opening Day starting lineup -- Cabrera, Gyorko, center fielder Cameron Maybin (torn left posterior cruciate ligament) and first baseman Yonder Alonso (broken bone, right hand) -- on the disabled list.

Despite the injuries, the Padres have played well. The loss Tuesday snapped their season-best, seven-game winning streak. All seven victories came against teams who have winning records -- Braves, D-backs and Giants.

Decker was promoted from Tucson on June 12 when Maybin landed on the disabled list. But he didn't appear in a game. He's hitting .260 with five home runs and 20 RBIs in 63 games for Tucson.

Gyorko continues making progress toward return

SAN FRANCISCO -- Rookie second baseman Jedd Gyorko has spent the last two days here walking around the clubhouse, conducting an audible countdown as to when he can come off the disabled list.

"Six days," Gyorko muttered several times on Tuesday.

Gyorko, on the disabled list with a right groin strain, is eligible to come off the disabled list on June 25. Gyorko has been with the Padres during this three-game road trip to AT&T Park and had a productive day on Tuesday.

"He's doing well," said Padres manager Bud Black. "He had a good day yesterday."

Gyorko, who continues to get treatment on the groin before games, did all of his work Tuesday before the Padres faced the Giants.

"I hit on the field, took ground balls right at me. It feels good. The training staff has done a great job. It's feeling a lot better than it did the first four or five days," Gyorko said.

"I turned some double plays, which was good. I took balls further to my left and right. I did some light sprint work in the outfield. It was good to pass that test. Hopefully I'll keep progressing."

Gyorko had a lighter workout Wednesday but Black said he would "ramp up" his activities on Thursday when the team returns to Petco Park to open a four-game series against the Dodgers.

There will likely be a Minor League rehabilitation stint in Gyorko's future, though Black indicated there wasn't a guarantee of one and, if there was one, it might not last long.

At the time of the injury, Gyorko was hitting .284 with eight home runs and 25 RBIs. He was hitting .325 in June after hitting .303 in May with six of his eight home runs.

At this point, Gyorko is beyond anxious to return.

"I don't see any reason why I can't come back and pick up right where I left off. It might be tough to get that timing back right away, but hopefully that doesn't take too long," he said.

Short hops

• The Padres have requested release waivers on infielder/outfielder James Darnell, who will miss the rest of the season with an injury to his left shoulder. Darnell suffered the injury swinging a bat last month. He was to visit Dr. James Andrews on Wednesday to determine if surgery is needed. Teams have 48 hours to claim Darnell. There's a chance the team re-signs him to a Minor League contract.

• The Padres have signed three more Draft picks; infielder Josh VanMeter (fifth round), first baseman Jake Bauers (7th) and right-handed pitcher Adrian De Horta (8th). All three will play for the Padres entry in the Arizona League. Games begin Thursday. The Padres have signed 24 players from their Draft class.

• Left fielder Carlos Quentin, who hasn't played since Friday because of a sore left shoulder, could be back in the lineup in a 'couple of days,' according to Black. Quentin will likely swing a bat soon.
