Marquis wearing cast, eager to return this year

PHOENIX -- The Padres have not announced who will replace injured starter Jason Marquis in the rotation on Monday nor have they ruled out the possibility that the veteran will return before the end of the season.

"There's a chance," Padres manager Bud Black said. "That's his motivation to come back and pitch. The doctors say we have to let the pain subside and let the healing start to occur."

Marquis suffered a fractured trapezium bone in his left hand on Tuesday after taking a line drive off his glove hand in the second inning against the Pirates. He was placed on the disabled list Thursday.

"Only time will tell. We will see," Marquis said. "As time goes and the healing process takes it course, we will see where it's at."

Marquis, who is wearing a cast, said he will continue to throw bullpens and hopes the swelling around the broken bone goes down during the next two weeks. The right-hander said he knew the hand was broken but continued to pitch.

"I love the game. I love being out on the mound and I love competing," he said. "It hurt but if you want to be on the mound, you have to deal with it sometimes."

Marquis is 8-11 with a 5.22 ERA in 22 starts this season. He's 5-3 with a 4.55 ERA in his last 10 games.

"If I'm able to pitch, I will. If it makes no sense, I won't," he said. "But my goal is to get on the mound as many times as I could."

For their part, the Padres believed placing Marquis on the disabled list was the right decision.

"If this was a situation, maybe late in the year, or a different type of season, then there might be a possibility that he could continue pitching," Black said. "It makes sense to let it heal in the short term. He's in a lot of pain. He's got a cast up to his elbow. Jason understands that."

Spence called up while Thayer on paternity list

PHOENIX -- The Padres recalled left-handed pitcher Josh Spence from Triple-A Tucson and placed right-handed pitcher Dale Thayer on the Major League paternity list.

In 11 games for the Padres this year, Spence, 24, is 0-1 with a 4.35 ERA and 10 strikeouts with five walks. He went 3-2 with a 5.17 ERA in 29 games for Tucson, including a 1-0 mark with a 3.60 ERA in his last 12 games.

Thayer, who is 2-2 with a 3.89 ERA, and his wife, Lisa, welcomed their third daughter early Friday morning.

Short hops

• Injured closer Huston Street (strained left calf) played catch Friday and remains on track for either a rehab assignment in the Minor Leagues or a simulated game with the big league club.

It's unclear when Street, who has 21 saves in 21 chances and boasts a 0.75 ERA this season, will pitch off a mound.

"There is no timetable, but we like the fact that he has turned the corner on this, where he is out on the field doing some things, and the time in the training room has been limited," manager Bud Black said. "That's always a great first step. The next step is to get him on the mound and throw."

• Anthony Bass (shoulder) threw two innings in a successful rehab assignment start Thursday for Triple-A Tucson and will start again in five days, Black said.

Bass and injured starter Andrew Cashner, who has been on the disabled list since July 4 with a strained right lat muscle, are both are expected to pitch for the big league club in September, the manager said.

• Everth Cabrera stole two bases Wednesday and is 24-for-24 in stolen-base attempts this season, the longest streak of successful attempts to start a season in club history.
