Twins third baseman Danny Valencia was held out of Sunday's 5-4 victory over San Diego because of a sore right triceps, but he hopes to play Tuesday when the Twins open a three-game series at San Francisco.

He hopes treatment Sunday and Monday will enable him to return to the lineup. "It feels a lot better than I thought it was going to feel," Valencia said.

Valencia, who homered for the only run of Saturday's 1-0 victory, was injured in the eighth inning making a throw to first. He said the pain initially was in his biceps but was more in his triceps Sunday.

"We don't think it's anything serious," trainer Rick McWane said.

Matt Tolbert filled in at third for Valencia on Sunday and delivered a key two-out, go-ahead double in the seventh inning.

Other injury updates • Designated hitter Jim Thome (back/quadriceps) worked out in Fort Myers, Fla., on Sunday after having his workout Saturday cut short by the flu. The plan is for him to get some at-bats in simulated games on Monday and Wednesday.

The Twins had held out hope that Thome would be available sometime during the upcoming road trip. But manager Ron Gardenhire pointed out that Thome hasn't played in any games in Florida yet.

• First baseman Justin Morneau (left wrist) will have the cast taken off Friday or Saturday. After that, he will need a few days to regain motion and strength. He could be swinging a bat a week after having the cast removed. "That doesn't mean he'll be back to playing games," McWane said, meaning Morneau might not return until the first full week of July.

• Righthander Kevin Slowey (abdominal strain) threw in the bullpen Sunday and is scheduled to appear in the simulated game Wednesday.

• Outfielders Denard Span (concussion) and Jason Kubel (left foot) remain out indefinitely.

Liriano not bad Francisco Liriano gave up three runs over seven innings on eight hits with two walks and two strikeouts Sunday.

But the Twins lefthander had the crowd stirring with excitement when he tore through the Padres batting order the first time through, striking out six of the nine batters he faced.

But eight batters reached base over the next two innings as the Padres took a 3-1 lead. Liriano settled down and retired seven of the final eight men he faced.

"The great thing about Frankie is that he has such good stuff that he can not be at his best and still get you deep into a ballgame," Gardenhire said.

The 1-0 show The Twins' 1-0 victory Saturday was the fourth time they have won by that score this season. They have also lost twice by 1-0 scores.

According to the Elias Sports Bureau, the Twins have played in 29 1-0 games since 2004, third-most in baseball. The top three: 1. San Diego, 38 (PETCO Park opened in 2004). 2. San Francisco, 32. 3. Twins, 29.

Etc. • Padres bullpen catcher Mark Merila, a former Gophers All-America from Plymouth, presented the lineup card to umpires before the game.

• Former Twins second baseman Orlando Hudson (left groin strain) was activated from the disabled list in time for Sunday's game and went 2-for-3 with an intentional walk and run scored for San Diego.
