Playing in San Francisco serves Stanton well

SAN FRANCISCO -- Giancarlo Stanton, who led the Major Leagues in RBIs and had the longest active hitting streak at 16 games going into Thursday's series opener against the Giants, loves to hit at AT&T Park.

Stanton has a four-game hitting streak against the Giants, as well as a career .702 slugging percentage at AT&T Park. He has nine doubles and four home runs in 14 games in San Francisco.

"He just continues to get better and better," manager Mike Redmond said. "He feels good, and he's healthy. He's making contact and putting the ball in play. It's great to see him getting base hits as well."

Tommy John surgery confirmed for Fernandez

SAN FRANCISCO -- Right-hander Jose Fernandez will undergo Tommy John surgery in Los Angeles on Friday, manager Mike Redmond confirmed before Thursday night's game with the Giants.

"The focus is to get him back," Redmond said. "It's good he's getting it done and have the recovery process begin."

Fernandez, the 2013 National League Rookie of the Year, was 4-2 with a 2.44 ERA before complaining of a sore right elbow during his most recent start, against the Padres on May 9.

After he was diagnosed with a tear in his ulnar collateral ligament, the team doctor recommended the season-ending surgery; Fernandez wanted to speak with his family about options before committing to it.

Fernandez went on the disabled list on Monday, and Anthony DeSclafani was called up to take his turn in the rotation on Wednesday.

The recovery time for the surgery, which will be performed by Dr. Neal ElAttrache, is usually between 12 and 18 months.

Fernandez, who was also named to the NL All-Star team and third in NL Cy Young voting last season, made his big league debut last April 7.

"When he was hurt we worried a lot about him," said Henderson Alvarez. "He's a huge loss for us. I'm sure he will work hard and return better than before."

Messages roll in for DeSclafani after debut

SAN FRANCISCO -- Right-hander Anthony DeSclafani heard from old friends and family after winning his Major League debut, Miami's 13-3 victory over the Dodgers on Wednesday.

"Nothing crazy," DeSclafani said before Thursday night's opener against the Giants. "My girlfriend, my family, my best friend. Those were all the people I needed to hear from. I did hear from people from high school and college."

DeSclafani attended Colts Neck High in New Jersey before playing for the University of Florida from 2009-11. He became the sixth player from coach Kevin O'Sullivan's 2010 SEC championship team to reach the Majors, joining Kevin Chapman (Astros), Matt den Dekker (Mets), Steven Rodriguez (Dodgers), Mike Zunino (Mariners) and Nick Maronde (Angels).

"I know there are going to be ups and downs throughout my career," DeSclafani said. "I just want to work hard to be consistent."

There are currently seven former Gators in the Majors: DeSclafani, Zunino, Mark Ellis (Cardinals), Darren O'Day (Orioles), Ryan Raburn (Indians), David Ross (Red Sox) and Cole Figueroa (Rays).

"We had reports that he had good command, but you never know what you're going to get until you get out under the lights," manager Mike Redmond said. "When you talk about Jose [Fernandez] being gone, it's an opportunity for someone to step up. He took advantage of that."
