NEW YORK (AP) Yankees right-hander Chase Whitley will have Tommy John surgery on Tuesday and miss the rest of the season.
The team made the announcement Monday during an off-day.
The 25-year-old Whitley left his start Thursday against Tampa Bay in the second inning because of pain in his elbow.
Whitley will have the surgery in New York. He was 1-2 with a 4.19 ERA in four starts this season.
Injured Yankees pitcher Masahiro Tanaka and Ivan Nova kept up their comebacks.
Tanaka, who hasn't pitched since April 23 because of right wrist tendinitis and a right forearm strain, threw 29 pitches Monday in a bullpen session at Nationals Park in Washington, D.C. Manager Joe Girardi said Sunday that a minor league rehab game Thursday was an option.
Nova is expected back next month from Tommy John surgery in April 2014. The righty threw 42 pitches over three innings against Philadelphia minor leaguers.
