BOSTON -- Ivan Nova's season appears to be over. The Yankees right-hander has been advised to have Tommy John surgery to repair a partially torn right ulnar collateral ligament.
Nova was examined on Tuesday by team physician Dr. Christopher Ahmad at New York Presbyterian Hospital in New York, where an MRI arthrogram confirmed the original diagnosis of a partial tear of the ligament.
The recovery time for Tommy John surgery is approximately 12 to 18 months.
"We had an inkling that was going to be the recommendation," manager Joe Girardi said. "It's unfortunate, and obviously he has to make a decision now. It's what you don't want to hear."
Girardi said that he had not spoken to Nova, who sustained the injury during Saturday's start against the Rays at Tropicana Field, but the Yankees have already decided how they will patch the hole left by Nova's departure.
Vidal Nuno, who pitched five scoreless innings in a spot start against the Rays on Sunday, will slide in as the fifth starter for the foreseeable future. Nuno's next start has been set for Saturday against the Angels at Yankee Stadium; Nuno has a 6.75 ERA in four games (one start) this year.
"He pitched extremely well," Girardi said. "Now you would think that you could move him to 80, 85 pitches the next time, which is almost where our starters were the first start; pretty close."
Girardi said that Nova has the option to seek another opinion before undergoing surgery. Nova was 2-2 with an 8.27 ERA in four starts for New York this season, including allowing a career-high four homers allowed in his last start.
"We had high hopes for him because of what he did at the end of last year," Girardi said. "His Spring Training was very, very good. We had big expectations for him. This is a blow to our rotation, but no one is going to feel sorry for you. As a ballclub, we have to figure it out."
• As a nod to Earth Day, which is being celebrated on Tuesday, the Yankees said that they will be giving away herb seed packets to the first 18,000 fans in attendance for Friday's game against the Angels at Yankee Stadium.
• By promoting Vidal Nuno to the fifth-starter's role and outrighting Cesar Cabral to Triple-A Scranton/Wilkes-Barre, the Yankees have gone from having three left-handers in the bullpen to just one: veteran Matt Thornton.
"It's not exactly what you want, but that's what it is," Girardi said. "We'll figure it out. We have confidence in our right-handers."
• On this date in 1959, Whitey Ford pitched a 1-0, 14-inning shutout against the Senators at Griffith Stadium, allowing seven hits with seven walks and 15 strikeouts. Moose Skowron hit a 14th-inning homer off Chuck Stobbs to provide the margin of victory.
