The San Diego Padres selected pitcher Jason Marquis from Double-A San Antonio and placed pitcher Eric Stults on the 15-day disabled list on Thursday.
Marquis, scheduled to start for the Padres on Thursday, made seven starts for the Minnesota Twins earlier this season and went 2-4 with an 8.47 earned run average in 34 innings.
The Padres signed Marquis to a minor league deal on May 29, a day after he was released by Minnesota.
In his only start with San Antonio, the 33-year-old right-hander went seven innings and allowed one run.
Marquis has already pitched for seven teams in his 13-year major league career, going 106-102 with a 4.63 ERA in 333 games -- 274 starts -- for the Braves, Cardinals, Cubs, Rockies, Nationals, Diamondbacks and Twins.
Stults, who suffered a strained left lat muscle, has gone 1-2 with a 4.44 ERA in four starts for the Padres this season. The left-hander was claimed off waivers from the Chicago White Sox on May 17.
To make room for Marquis on the 40-man roster, the Padres transferred infielder Jason Bartlett to the 60-day DL. Bartlett, who was originally placed on the disabled list on May 17 with a strained right knee, hit .133 with five doubles and four RBI for the Padres this year in 83 at-bats.
