DENVER -- The Padres made a number of roster moves on Monday, which featured the return of center fielder Cameron Maybin.

In addition to reinstating Maybin from the 15-day disabled list, the Padres selected the contract of right-handed pitcher Anthony Bass from Double-A San Antonio, and the 23-year-old made his first Major League start to open a three-game series against the Rockies.

In corresponding moves, the Padres placed right-handed pitcher Aaron Harang (right foot contusion) on the DL, retroactive to June 10, and optioned catcher Kyle Phillips to Triple-A Tucson. To make room on the 40-man roster for Bass, San Diego also designated left-handed pitcher Aaron Poreda for assignment.

Maybin, who hadn't played since May 27 while suffering through right knee inflammation, went 2-for-10 with a double, an RBI and a stolen base in three rehab starts for Triple-A Tucson.

"I'm looking forward to [playing]," said Maybin, who started in center field and batted eighth in his return on Monday. "It's been about two weeks too long. I'm looking forward to running around, man, and just being a part of the mix."

Maybin began feeling discomfort in his knee during the Padres' last trip to Colorado from May 13-15, which was, coincidentally, one of his best offensive series of the season. Maybin hit .500 (6-for-12) with two home runs and three RBIs as the Padres took two of three from the Rockies.

"It's cool, but that's in the past," Maybin said. "They've got a good guy on the mound for them tonight [in right-hander Aaron Cook], so I've just got to try to come out and contribute. That's the biggest goal. It should be fun."

Maybin said he felt no pain in his knee during the rehab assignment and doesn't expect to limited in his return.

"I can play as hard as I need to," he said.

Moseley scratched from Tuesday's start

DENVER -- The Padres still hadn't announced a starter for Tuesday before opening up a three-game set against the Rockies at Coors Field on Monday, but San Diego manager Bud Black said the start won't go to right-hander Dustin Moseley.

Moseley suffered a dislocation of his non-throwing shoulder during his start against the Rockies on Wednesday. Moseley threw about 35 pitches during a bullpen session on Monday, and Black said he doesn't expect the righty, who was injured while swinging at a pitch, to make a trip to the disabled list.

"He will skip this start but will be able to jump back into the rotation by this weekend," Black said.

San Diego's manager said the announcement of Tuesday's starter would come after Monday's game. Black said the decision will likely involve a personnel move, which means the Padres may recall left-hander Wade LeBlanc from Triple-A Tucson.

LeBlanc was scheduled to start for Tucson on Monday, but he was scratched.

LeBlanc took the loss in his only start of the season on April 24 against Philadelphia, but he was solid, allowing three runs on nine hits over eight innings, while striking out two and walking four.

Hudson approaches rehab stint

DENVER -- Padres second baseman Orlando Hudson is nearing a return to action.

Hudson, on the 15-day disabled list after suffering a groin strain on May 25, ran the bases, fielded ground balls and took batting practice at Coors Field on Monday.

Padres manager Bud Black said Hudson could begin a rehab assignment, likely coming with Class A Lake Elsinore, as early as Wednesday.

"He's getting closer," Black said.

In his first season with the Padres, Hudson is hitting .217 with seven RBIs.
