SAN DIEGO -- Going into last Monday's non-waiver Trade Deadline on the disabled list, Carter Capps wasn't expecting to be traded from the Marlins. But the 25-year-old said he couldn't have asked for an easier transition to San Diego after learning from his wife that he was going to the Padres.

"She saw it on Twitter," Capps said with a laugh. "Pretty typical these days, I guess."

Capps was one of the league's best relievers in 2015 -- his 1.10 FIP was the lowest among pitchers with 30 or more innings -- before undergoing Tommy John surgery on March 8. He is ahead of schedule in the rehab process, already throwing 75 times from about 45 feet Wednesday, and he is hoping to throw again Thursday.

"Everything's felt good," Capps said. "Back to throwing and just feeling good. … Obviously, the goal is to be back by spring."

Padres manager Andy Green said that Capps has been in the weight room constantly since joining the team, but he might need a bit of cautioning going forward.

"I think he's the kind of guy that you've got to pull the reins in on," Green said. "He just wants to go, go, go, is what I've been told. And his throwing, the way the ball's coming out, it's way more live than it should be at this point in time.

"I don't know how you take that, if that's a good thing or a bad thing, but he definitely wants to be out, wants to be throwing, wants to be moving forward. He's definitely -- by doctors and training regimen schedules -- he's ahead of schedule."

Ross gets back on the mound

After suffering a setback in his rehab from right shoulder inflammation, thanks to a left ankle injury that prevented him from throwing on a slope, Tyson Ross finally got back on the mound Tuesday.

Green said that Ross threw five pitches to a catcher standing up, and five to a catcher down, in what was simply a "test it out" session.

"It was good, so I think he's scheduled for a bullpen in the next few days, and that [rehab] progression begins again," Green said. "I don't think it's going to take as long as it did last time. He's still going to have to throw a number of 'pens before he throws to hitters, but he's been throwing 275 feet. His shoulder feels good."

Ross hasn't thrown in a game since Opening Day, but Green is hopeful that the 29-year-old will be able to make a few starts for the Padres in September.

"I can still see a scenario where he gets three or four starts before this year is over," Green said. "We build him up, [he] goes through Minor League rehab, by the time their season is ending, he ends up pitching with us for September."

Injury updates

• While the team is still waiting to announce an official diagnosis for Colin Rea , Green was not expecting the 26-year-old to be back any time soon.

"More than likely, it's going to be a long road back for him," Green said.

• Jon Jay (right forearm fracture) was walking around the clubhouse without a cast or brace Wednesday, but he is still a few weeks from picking up a bat and taking swings. Green said that he was doing exercises, and he wanted to see him get a month of baseball in before the season's end. In that scenario, Jay would not go back to an everyday center-field role, but he would get regular playing time at all three outfield spots while allowing the current outfielders to continue getting on the field regularly, as well.

• Green said it was looking "less and less likely" that César Vargas (right flexor strain) will pitch this season. With Vargas and Jon Edwards (right flexor strain), the team would still want to make sure both are built up and healthy going into the offseason so complications don't arise in Spring Training.
