Skaggs has Tommy John surgery

ANAHEIM -- Angels left-hander Tyler Skaggs underwent successful Tommy John surgery on Wednesday, manager Mike Scioscia said.

On Sunday, the Angels announced that Skaggs, 23, would miss the rest of this season and all of next season. Skaggs last pitched July 31 in Baltimore, where he threw 4 2/3 innings of no-hit ball before exiting.

Tommy John surgery typically sidelines a pitcher for 12-18 months, but the Angels said they wouldn't rush Skaggs back to be able to pitch next season.

"The protocol for rehabbing Tommy John surgery is pretty specific, and it's plainly laid out and it's going to be, it'll be a process," Scioscia said. "Like we talked about the last couple of days, it's probably one of the more predictable surgeries as far as an outcome as you could have. We'll just look to see Tyler sometime in the spring of 2016."

Skaggs was 5-5 with a 4.30 ERA in 18 starts for the Angels, who were relying on him to be the club's No. 4 starting pitcher. Instead, the Angels will bank on Matt Shoemaker (10-4, 3.89 ERA) and Hector Santiago (3-7, 3.59 ERA) to continue their recent success.

Pestano thrilled to be back home with Angels

ANAHEIM -- When he walked into the Angels' clubhouse on Sunday morning, Vinnie Pestano carried a navy blue duffle bag with him -- but the bag didn't have the Angels' familiar trademark emblazoned on it.

Instead, it was stamped with the logo of the Columbus Clippers, Cleveland's Triple-A affiliate.

It's been that kind of week for Pestano, who was traded from the Indians, optioned to Triple-A Salt Lake and recalled to the Angels across three hectic August days that landed the 29-year-old right-hander back in Orange County.

"I go from the middle of a road trip in Pawtucket, Rhode Island to Scranton, Pennsylvania to being on the Angels, being 20 games above .500 and in the playoff hunt," Pestano said. "It's great. Being from here, growing up watching the Angels play, was the cherry on top.

"A lot of plane flights, a lot of early mornings."

Pestano was born in Newport Beach, attended high school in Anaheim and played college baseball at Cal State Fullerton. On Sunday, he made his first appearance in Anaheim since 2012 and his first with the Angels.

He threw a scoreless ninth inning, striking out three batters and walking one.

"It was great to get out here the other day, get the first one out of the way because I was a little nervous," Pestano said, "probably more nervous for this debut than I was for my Indians debut a few years ago."

Pestano's homecoming was a subdued one because he didn't hear about his callup until around 2 a.m. on Sunday morning, so his family and friends had to watch his Angels debut on television instead of at Angel Stadium.

He was traded from Cleveland on Thursday for right-handed pitching prospect Michael Clevinger. With the Indians, Pestano appeared in 192 games and posted a 2.93 ERA across five seasons.

Morin targeted for Saturday return

ANAHEIM -- Injured Angels reliever Mike Morin will make a rehab appearance Thursday night for Class A Advanced Inland Empire, manager Mike Scioscia said.

Morin is expected to come off the 15-day disabled list on Saturday at Texas after recovering from a left foot laceration sustained while walking on a Florida beach. He last pitched on July 31 and has a 2.36 ERA this season.

Both infielder Grant Green (lumbar strain) and pitcher Joe Thatcher (left ankle sprain) will continue their treatment and recovery in Arizona when the Angels embark on a 10-game road trip.

Green has been able to work on his defense and hitting, but Scioscia said there was still no timetable for his return despite a lot of progress.

Thatcher, who was out of a walking boot last week, said he was aiming to return for the Oakland series at the end of the trip.

Worth noting

• The Angels outrighted right-hander Caleb Clay on Wednesday, removing him from the club's 40-man roster.

The move drops the Angels' 40-man roster to 39 players, freeing up a spot that could potentially be used on an emergency starter, should the club have a need for one. Wade LeBlanc, Randy Wolf and Chris Volstad are possible spot starters, but none of them are on the current 40-man roster.

Clay was recalled on Sunday to add length to a tired bullpen and was optioned Tuesday before making his Major League debut.

• Amid the Angels' current offensive slump, David Freese has quietly put together a nine-game hit streak.

In his last 41 at-bats entering Wednesday's finale vs. the Phillies, Freese was hitting .366 and had 22 RBIs in his previous 37 games.

"I think there's still more in David," Scioscia said. "Hopefully, he's going to be a guy that contributes when he can this last six, seven weeks of the season because he's important to us."
