SAN FRANCISCO -- The Padres added two relievers to their 25-man roster before Wednesday's game against the Giants.

The club selected the contract of right-handed pitcher Marcos Mateo from Triple-A El Paso and recalled righty Kevin Quackenbush from El Paso.

After Tuesday's 3-2, 11-inning victory over the Giants, the team optioned righty Nick Vincent to El Paso, as Vincent threw 33 pitches in the game and wouldn't have been available for Wednesday's game.

The club also placed right-handed reliever Dale Thayer on the 15-day disabled list, retroactive to June 17, with a strained right shoulder.

To make room for Mateo on the 40-man roster, the Padres moved right-handed pitcher Brandon Morrow (right shoulder inflammation) from the 15-day DL to the 60-day DL. The righty, whose DL stint is retroactive to May 3, could begin a Minor League rehabilitation stint in the next week. He would then be eligible to rejoin the Padres on July 3.

Quackenbush has a 3.10 ERA in 20 1/3 innings this season with the Padres. This is the second time he's been promoted from El Paso. He was optioned there on June 10.

Mateo, 31, had a 1.86 ERA with nine saves with El Paso. He had 39 strikeouts in 29 innings and allowed 17 hits.

Mateo K's Szczur

Mateo, who signed a Minor League free-agent deal with the Padres in January, last appeared in the Major Leagues on July 4, 2011, as a member of the Cubs. He had a 5.04 ERA in 44 2/3 innings with the Cubs from 2010-11.

The Padres were impressed with Mateo's work last year in the Dominican Winter League, where he was named MVP and Pitcher of the Year after posting a 1.75 ERA and a league-best 21 saves.

Then-Padres senior vice president Omar Minaya saw him last winter, as did some of the team's Dominican scouting staff. In January, Minaya left the Padres to become a special adviser to Major League Players Association head Tony Clark.

"I went into the offseason and winter ball trying to get better," Mateo said through an interpreter. "The numbers that I put up in the Dominican put a lot of attention on his name. The Padres came to me and offered a job. I went up there and took it. I just wanted to prove that I'm a good pitcher and deserved another chance."
