HOUSTON -- The Padres claimed right-handed pitcher Mark Hamburger off waivers from the Rangers on Monday, moving outfielder Jeremy Hermida to the 60-day disabled list.
Hamburger, 25, was optioned to Triple-A Tucson. At Triple-A Round Rock in 2012, Hamburger made 21 appearances, going 0-2 with a 6.55 ERA in 45 1/3 innings. He threw eight innings in relief appearances for the Rangers in 2011, giving up four runs.
The Rangers designated Hamburger for assignment on June 22 to clear a spot on the 40-man roster for Roy Oswalt.
Hermida, 28, has been on the 15-day disabled list since April 28 (retroactive to April 27) with a strained left abductor. He has missed 53 games so far.
Hermida will still start a Minor League rehabilitation stint this week and is set to return in a week or two. Sending him to the 60-day disabled list is mostly a procedural move.
In 13 games in April, Hermida hit .250 (6-for-24) with two RBIs.
Veteran Wells recalled to make Tuesday start
HOUSTON -- Three years removed from his last Major League start, 35-year-old journeyman Kip Wells will start for the Padres on Tuesday against his hometown Astros.
Wells will be the 13th different starter this season for the Padres, who optioned Andy Parrino to Triple-A Tucson after Monday's 8-7 victory to make room for Wells on the roster. The right-hander still lives in Houston and was already in the Padres' clubhouse at Minute Maid Park on Monday afternoon.
Wells hasn't pitched in the Majors since 2009 with the Reds. After being released by Cincinnati before the 2010 season, he briefly pitched for the independent Long Island Ducks.
In 2011, Wells was unofficially retired, not by choice. He even watched a few games at Minute Maid Park, but said he didn't enjoy watching others play the game he felt he was still capable of playing at a Major League level.
"This is a pretty unique business," Wells said. "It's not like an insurance salesman or a car salesman where you can get on with another company."
After spending Spring Training with the White Sox, Wells was released on April 16. He signed with the Padres on May 8 and was sent to Tucson. In seven starts, Wells was 1-4 with a 4.97 ERA. He had an 8.22 ERA in his last three starts, earning a loss in all three games.
Manager Bud Black said the Padres scouts and Triple-A staff all said Wells still has Major League stuff and just needs to make pitches like anybody else. Wells also brings 11 years of Major League experience.
"He's pitched in Major League games, and he's pitched in a lot of them," Black said. "The expectation is you hope for the best, for him and the club. And he goes out and pitches a good ballgame."
Wells will look to avoid his 100th career loss on Tuesday. He is 67-99 in the Majors with a 4.71 ERA. He said he definitely will have family and friends in the crowd.
"To be here now, it's a good story, but it remains to be seen what the end chapter looks like," Wells said.
Alonso out of lineup, hopeful to play Tuesday
HOUSTON -- First baseman Yonder Alonso sat out his second straight game with a sore left knee on Monday, but manager Bud Black was optimistic about Alonso's chances to play in some fashion Tuesday.
"He's feeling much better today," Black said.
Alonso had an injection in the knee on Saturday night to reduce some of the soreness. Doctors said Alonso would need 48-72 hours to feel healthy.
The 25-year-old rookie is batting .254/.325/.345 with two homers and 18 RBIs.
Jesus Guzman started at first base on Monday and batted fifth against Astros left-hander Wandy Rodriguez. Guzman entered the game batting .236 with one homer and 24 RBIs.
• Former Padres prospect Anthony Rizzo will make his debut for the Cubs on Tuesday. The Padres traded Rizzo to the Cubs in January with pitcher Zach Cates, getting pitcher Andrew Cashner and outfielder Kyung-Min Na in return.
Rizzo, a 22-year-old first baseman, batted .143 in 128 at-bats for the Padres in June and July last year before being sent back down to the Minor Leagues.
• Monday marked the start of a 10-game road trip for the Padres, with stops in Houston, Colorado and Arizona.
