SAN FRANCISCO -- Jose Fernandez will undergo Tommy John surgery on Friday in Los Angeles to replace the torn ulnar collateral ligament in his right elbow. Dr. Neal ElAttrache of the Kerlan-Jobe Clinic will be performing the procedure.
"It's been a process for him, and I'm glad he's having it done and starting the recovery process as soon as possible," said manager Mike Redmond.
Fernandez will be going under the knife exactly one week to the day of his last start in San Diego.
Anthony DeSclafani was so impressive in winning his major league debut Wednesday against the Dodgers that Redmond said he'll remain in the rotation.
"He'll make his next start," Redmond said. "Did great."
But that creates a surplus of long relievers in the bullpen. Most teams have just one long guy. But with the signing of Randy Wolf, the Marlins now have three. Kevin Slowey and Brad Hand have also been used in that role.
As a result, Redmond said Hand's role will change.
"We're going to probably need to have Hand fill that Dan Jennings role, come out and face early lefties," Redmond said. "We're probably going to ask him to do a little bit more and get out of that long reliever mentality, and get him into situations in which he starts to face some lefties early in the game."
There have only been three, 3-inning saves this season in the majors, and two of them belong to Marlins relievers: Hand and Wolf.
Wolf recorded his first big-league save Wednesday when he took over for DeSclafani in the seventh and covered the final three innings of the Marlins' 13-3 victory.
Wolf said notching a save has always been on his bucket list.
"I would call it a technicality save," Wolf said.
Giancarlo Stanton takes a 16-game hitting streak into tonight's series opener against the Giants. What's interesting about Stanton's career-long streak is that he's doing it mostly with singles, not home runs. He's hit only four homers during the streak, as well as five doubles.
Stanton is hitting .421 during the streak, which began on April 29. Of his 24 hits during that time, 15 have been singles.
