Cain needs surgery, likely done for the season

NEW YORK -- Yielding to a unanimous decision from a panel of medical experts, Giants right-hander Matt Cain almost surely will undergo surgery to have bone chips and spurs removed from his throwing elbow.

Given the minimum recovery time for such a procedure, which is around three months, the surgery will end Cain's 2014 season. However, he said Friday that he hasn't decided when he'll have the operation.

"If you're putting odds on it, odds are going to be that he will not pitch," Giants manager Bruce Bochy said.

Cain briefly played catch at a 60-foot distance on flat ground at Citi Field to gauge the feeling in his arm one more time. He indicated that he'll decide when to schedule the surgery after he evaluates how his arm feels following that exercise. He conceivably could wait until early in the offseason to have the procedure and still be ready for Spring Training.

Bochy said that Cain needed this mental and physical pause.

"This will give him the weekend to decide who's going to do [the surgery] and when," Bochy said.

Cain visited renowned orthopedist Dr. James Andrews on Tuesday and consulted Dr. David Altchek, the Mets' highly regarded medical director, on Friday. They agreed with the evaluation of Giants orthopedist Dr. Ken Akizuki.

"All three said the same thing," Cain said. "[The chips and spurs] need to come out."

Cain, 29, said that he has had a "good bit of bone chips" in his elbow for 10 years. Yet he managed to make three All-Star teams and excel in two postseasons with this hindrance.

"They've always been there," said Cain, who's 2-7 with a 4.15 ERA in 15 starts this season. "It's just that now they're mad and they're letting me know about it. For some reason, they got in a different spot and they got aggravated and they are what they are now."

Cain said it was unlikely that the chips could migrate back to an area of his elbow which would free him from discomfort.

Giants general manager Brian Sabean didn't panic over the first arm-related ailment endured by Cain, who pitched 200 innings or more in each season from 2007-12. Asked if Cain's surgery would change the Giants' offseason priorities -- in other words, would they target starting pitching more seriously than usual -- Sabean replied, "I'd say it wouldn't. But it hasn't happened yet."

In other injury-related news, Bochy said that center fielder Angel Pagan (back) was expected to play seven innings for the Giants' Arizona League affiliate on Friday, then would progress to Triple-A Fresno if all went well. Asked if it was "reasonable" for Pagan to rejoin the team during the Milwaukee series that begins Tuesday, Bochy replied, "I'd say."

Recovering from a concussion, first baseman Brandon Belt further increased his baseball-related activities and should soon be activated from the disabled list, unless the Giants determine that he should begin an injury rehabilitation assignment in the Minors.

Giants designate Uggla, Colvin, call up Double-A duo

NEW YORK -- The Giants' decision-makers believed that the club needed a jolt after losing 29 of its previous 45 games, many of which featured meager offense.

So San Francisco reached into the Minors -- a little more deeply than might be expected -- to change the scenery Friday.

The Giants purchased the contracts of infielder Matt Duffy and outfielder Jarrett Parker from Double-A Richmond while clearing roster room by designating second baseman Dan Uggla and outfielder Tyler Colvin for assignment.

With first baseman Brandon Belt (concussion) and center fielder Angel Pagan (back) likely to return soon from their respective ailments, either Duffy or Parker could return to the Minors shortly.

But Duffy and Parker pique genuine interest within the organization. And promoting players from Double-A is hardly unique for the Giants, who did it with third baseman Pablo Sandoval (2008), outfielder Darren Ford (August 2010) and left-hander Eric Surkamp (August 2011).

Duffy, 23, hit .332 with a .398 on-base percentage in 97 games at Richmond.

"He's got a base-hit bat," Giants general manager Brian Sabean said of Duffy, a right-handed hitter who started Friday night's series opener at second base. Manager Bruce Bochy said that Duffy would platoon with lefty-swinging Joe Panik.

Duffy, the Giants' No. 18 overall prospect, collected his first Major League hit and RBI with a single in the seventh inning against the Mets.

"I didn't feel as nervous as I thought I would," Duffy said.

Parker, 26, can play all three outfield positions and has displayed power with 12 home runs. He also has struck out 583 times in 2,004 Minor League plate appearances.

"I think I've gotten a lot better recently," said Parker, who hit .330 in July.

Both thought that they were about to be sent packing Thursday morning when Richmond manager Russ Morman ordered them not to board the team bus to Altoona, Pa. The non-waiver Trade Deadline was just a few hours away, and either could have been included in a multiple-player deal. Assistant general manager Bobby Evans called them about 20 minutes after the Deadline passed with the happy news they least expected.

The reality of spending their first day as Major Leaguers in the nation's biggest city had just begun to dawn on Duffy and Parker as game time approached.

"It's not the Super 8 in Altoona," Parker said.

Bochy dispelled the notion that the Giants, who entered Friday having lost ground to the Los Angeles Dodgers in the National League West race in seven of the previous eight days, had begun looking more toward 2015 by promoting Double-A performers.

Bochy said that he, Sabean and the rest of the club's brain trust conducted plenty of discussions about the team recently, mainly due to Thursday's Trade Deadline.

"I assure you there has not been one talk about 2015," Bochy said.
