Left-hander Tallet signed to Minor League deal

SAN DIEGO -- The Padres signed left-handed pitcher Brian Tallet to a Minor League contract on Saturday -- and pressed him into duty right away with Triple-A Tucson.

Tallet, 34, was with the Pirates' Triple-A affiliate before signing with the Padres. He's a nine-year Major League veteran having pitched for three teams (Blue Jays, Indians and Cardinals).

Tallet's best season came with the Blue Jays in 2008 when he had a 2.88 ERA in 51 appearances. He split last season between the Blue Jays and Cardinals.

Tallet pitched two innings in relief for Tucson on Saturday against Fresno. He allowed one run on two hits with four strikeouts.

Tucson needed a pitcher after reliever Brad Brach was added to the Padres' Opening Day roster on April 5 after Tim Stauffer went on the disabled list with a strained right elbow.

Moseley placed on DL with shoulder strain

SAN DIEGO -- Pitcher Dustin Moseley first felt some soreness in his right shoulder on Wednesday when he threw a routine bullpen session at Petco Park.

But it wasn't until his start Saturday against the Dodgers when he realized that something was wrong, especially after making a pitch to Matt Kemp in the fifth inning.

"I felt something [in the shoulder area] and turned around and looked up at the [scoreboard]. It said 84 mph changeup. That's when I said something is going on."

Moseley had thrown a fastball, not a changeup, and a marked decrease in velocity only validated that he had something wrong with his shoulder. He said the pain is more in the back of the shoulder toward his armpit.

On Sunday, the Padres placed Moseley on the 15-day disabled list with what is termed a strained right shoulder. The team recalled left-handed reliever Josh Spence from Triple-A Tucson to take his spot on the 25-man roster.

Spence pitched one scoreless inning in relief on April 6 for Tucson, allowing two hits.

As for Moseley -- who allowed five runs on five hits in five innings against the Dodgers -- he expressed disappointment of having to go on the disabled list, especially so early in the season.

"I've got a million things going through my head," said Moseley, who will undergo an MRI on Monday to make sure there's no damage to the shoulder joint. "It's disappointing for me. All the work I did for my left [shoulder], I did for my right."

Moseley had offseason surgery on his left shoulder to ensure he doesn't suffer any dislocations like he had twice last season while swinging a bat in a game. He pitched well in spring and did not have any issues -- with either shoulder.

"I think it's frustrating for Dustin because he had a good spring and he was really looking forward to this year," Padres manager Bud Black said. "We hope this is a mild injury that he can come back from."

Owings' long relief outing helps save bullpen

SAN DIEGO -- Micah Owings did the rest of the Padres bullpen a big favor on Friday when he threw 3 1/3 innings of scoreless relief in a 6-0 loss to the Dodgers.

Owings, the team's designated long reliever, was pressed into duty when starting pitcher Cory Luebke left the game after 4 2/3 innings.

Owings allowed one hit and had two strikeouts and, more important, threw 53 pitches -- 53 pitches that didn't have to go to someone else.

That, of course, became even more important Saturday when the Padres needed 91 pitches from six relievers in a 6-5 loss in 11 innings to the Dodgers.

"That's a critical role," Padres manager Bud Black said. "You would love to have your starters go six-plus [innings] every game but you're going to have games where you need that length, someone to throw 50 to 60 pitches.

"With Micah, he's proven he has the ability to do it. He saved two guys from pitching."

Black said Sunday that pitcher Anthony Bass will either start on Thursday [Dustin Moseley's normal spot in the rotation] or Saturday when the team needs a fifth starter for the first time this season.

The leading candidate for the other start is likely right-hander Joe Wieland, who is regarded as one of the Padres' top prospects.
