MILWAUKEE -- On Monday, Padres manager Bud Black said right-hander Jason Marquis will miss the rest of the season with a significant tear to the ulnar collateral ligament in his right elbow.
On Tuesday, Black had a chance to talk with Marquis, who confirmed he had a complete tear, but added that he will have reconstructive elbow surgery and that he intends to pitch again.
"I think, as of right now, he plans on pitching again," Black said of the 34-year-old Marquis, who has been in the big leagues since 2000. "I think he wants to come back and compete."
Marquis allowed six runs on eight hits and three walks in 5 1/3 innings in a loss to the Cardinals on Friday. He was hit hard and his velocity was down slightly from where it typically is. Marquis informed Black and the training staff afterwards of pain in his elbow.
Marquis was 9-5 with a 4.05 ERA in 20 starts this season. He was 9-2 with a 3.63 ERA in his first 14 starts, and the team was 10-4 in those games. But he never got that elusive 10th victory, going 0-3 with a 5.13 ERA in his last six starts.
Black wasn't entirely sure if Marquis would have the surgery, given his age and the 1,921 innings he's logged in the Majors with eight teams.
"But if that burning desire is there to compete and play … then do it," Black said.
The manager added there's a chance Marquis could have surgery as soon as next week. Black was unclear where the surgery would take place, but did mention Marquis' relationship with Reds team doctor Timothy Kremchek. It was Kremchek who diagnosed the torn UCL.
O'Sullivan will temper nerves this time around
MILWAUKEE -- Right-hander Sean O'Sullivan, who'll start for the Padres on Wednesday, can't predict how he'll fare against the Brewers.
O'Sullivan is sure of one thing, though. He won't be nearly as nervous as he was on July 12 when he made his first start -- a 10-1 loss to the Giants at Petco Park in which he allowed two runs in five innings, with four strikeouts and three walks.
That the game was played in front of a sold-out crowd of 42,361 did little to alleviate his anxiety.
"There were some extra nerves and excitement going into that one, pitching for my hometown team," O'Sullivan said. "It was almost like it was my [big league] debut all over again."
On Wednesday, O'Sullivan will make his second start with the Padres. He pitched two innings in relief on July 19 against the Cardinals, allowing three runs, and moved into the rotation after Jason Marquis landed on the disabled list with a torn ulnar collateral ligament in his right elbow.
In the start against the Giants, O'Sullivan needed 102 pitches to get through five innings.
"My goal this time is to go farther into the game, that's something I take pride in," O'Sullivan said. "And I want to attack the zone. They [Giants] were spoiling good pitches, turning them into six-, seven-pitch at-bats. I'm looking for early contact and turning it over to our defense."
Tweak to slider helping Street succeed
MILWAUKEE -- Closer Huston Street wouldn't normally do this, but when things turned bad for him early in the season -- he allowed 10 home runs in his first 26 1/3 innings -- he welcomed the input of a variety of his peers and members of the coaching staff.
"I'm very lucky to have [manager] Buddy Black, [pitching coach] Darren Balsley and [bullpen coach] Willie Blair, and my teammates … these guys see things," Street said before Tuesday's game. "I wouldn't normally do that, but it needed to be said."
Balsley started having Street use a different grip on his slider that, ideally, would produce a tighter spin and offer a sharper break.
Street has leaned on that slider a lot lately, and he hasn't allowed a run in his last six appearances. In a 5-3 win over the Brewers on Monday, Street worked a 1-2-3 inning for his 17th save this season in 18 opportunities.
"The last three weeks have started to feel more right for me," said Street, who wasn't needed in Tuesday's 6-2 win over the Brewers.
Street's struggles -- the four losses, the one blown save, the number of base runners -- were something he wasn't accustomed to.
"We're all competitive. So you balance your ego with how you're helping the team," Street said. "I felt I was doing a good job in the save situations. But the other part, you have to still be able to execute your pitches."
Street feels he's in a better place now than he was a month ago, though he's still wary about getting too far ahead of himself.
"I've been at this point of the year with six blown saves and with no blown saves," Street said. "It's a full season for a reason. There are still a lot of games left and a lot of pitches left to make."
• Left fielder Carlos Quentin was out of the starting lineup on Tuesday with a sore right wrist. He was available to pinch-hit, according to Black, who said the soreness wasn't considered serious. Quentin is expected to be in the lineup on Wednesday.
Mark Kotsay started in left and hit seventh. He went 3-for-4 with an RBI single and a run in the 6-2 win. It was his first multi-hit game since May 14.
• In order to make room for Tuesday's starter Tyson Ross on the team's 25-man roster, the Padres sent reliever Miles Mikolas to Triple-A Tucson. Mikolas, who pitched only one inning despite being added to the big league roster three separate times since June 23, was told after Monday's game.
