SAN DIEGO -- The Padres selected the contract of right-handed pitcher Tim Stauffer from Triple-A Tucson and placed outfielder Carlos Quentin on paternity leave on Friday.
Stauffer will be used a long reliever.
To make room for Stauffer on the 40-man roster, the team designated right-handed pitcher Thad Weber for assignment.
Stauffer, who started Opening Day for the Padres in 2011, had a 2-2 record with a 3.16 ERA over eight starts with Tucson.
"It was encouraging, from a health standpoint, it felt good and from a pitching standpoint, I was able to build on some things. I felt I was throwing the ball the way I needed to throw the ball," Stauffer said.
Stauffer signed a Minor League deal with the team before Spring Training after having surgery on Aug. 31 to repair the flexor tendon in his right elbow. The elbow felt good in Spring Training and then after the regular season started.
"There were times during Spring Training. But I think it wasn't until I was on a regular five-day starting [program] when I started feeling stronger and was able to go deeper into games," Stauffer said.
The Padres will carry, for now, three long relievers -- Anthony Bass, Tyson Ross and Stauffer.
"We'll see how it plays out … it's a nice luxury to have," said Padres manager Bud Black.
Stauffer had a June 1 opt-out clause in his contract, though he had no way of knowing if there were other opportunities with other teams.
"In that situation, you're showcasing yourself to other teams as well," Stauffer said. "Obviously, this was my first preference."
Stauffer, who was the fourth overall pick in the 2003 First-Year Player Draft by the Padres, is 23-31 with a 3.94 ERA in 96 games with the Padres, including 70 starts. His best season came in 2010 when he had a 1.85 ERA in 32 games.
Quentin, who missed Thursday's 6-2 loss to the Nationals, can miss a maximum of three games while on paternity leave. Quentin's wife, Jeane, gave birth earlier Thursday to the couple's first son, Clark.
Black said Quentin will return Saturday.
Weber had a 2.00 ERA in two games and nine innings with the Padres. He was 4-1 with a 3.93 ERA over six starts with Tucson.
Blanks comfortable with spot start at first
SAN DIEGO -- Before Friday's game against Washington, Padres outfielder Kyle Blanks made sure to get extra work in defensively -- but this time it was at first base.
Blanks took time fielding hard ground balls to his left and right, firing to second base to start a double play or flipping to first base where Padres manager Bud Black acted as the pitcher covering the base.
Friday marks the first time this season that Blanks will start a game at first base for the Padres. However, he did play first base earlier this season -- for only an inning -- and he could barely even remember it.
"It's been a while," Blanks said.
Blanks came up through the Minors as a first baseman before he was moved to the outfield in 2009.
He still takes grounders often just to make sure he keeps himself fresh for when he's needed at first. First baseman Yonder Alonso got the day off, although he has appeared in all 40 games for the Padres this season.
"I think you'll see any guy in here that plays multiple positions will always make sure they get the proper repetition," Blanks said. "That's one of those things that I feel like as long as I stay current, always kind of covering those bases and go into the game comfortable, I'm happy."
Blanks is hitting .245 in his 21 games this season, mostly as a player coming off the bench.
"If my name's on that paper, regardless of where it is, that's really all that matters," Blanks said. "I think that just being available at all those positions lends you to being a little more flexible, and if it allows you to get into more games, that's all you can ask for."
