NEW YORK — Texas Rangers catcher Melvin Novoa was suspended for 56 games under baseball’s minor league drug program following a positive test for the banned performance-enhancing substance Clostebol.

In addition, Boston Red Sox catcher Jhon Nunez was suspended 25 games, the commissioner’s office said Monday. A 25-game suspension is the penalty for a first violation for use or possession of a syringe at a team facility, in team-provided housing or while traveling with a club.

Novoa, 19, is to start serving his penalty when the Arizona League season begins.

The 21-year-old Nunez hit .316 (6 for 19) with one RBI this year for Greenville of the Class A South Atlantic League and is on the roster of Lowell of the Class A New York-Penn League, which starts play this weekend.

There have been 57 suspensions this year under the minor league drug program.

TIGERS: Designated hitter Victor Martinez was out of Monday’s starting lineup against the Chicago White Sox because of irritation in his right knee.

Martinez had an MRI on Monday morning, and Manager Brad Ausmus says it showed “no major structural issues.” The 37-year-old Martinez says he isn’t concerned and joked he is just “getting old.”

Martinez is hitting .333 with nine homers and 35 RBI in 60 games.

Outfielder J.D. Martinez replaced Victor Martinez at DH in the opener of a three-game series against the White Sox.

Ausmus says Victor Martinez is available to hit and will be evaluated daily.

YANKEES: Ike Davis finalized a one-year contract, giving New York more options after putting four first basemen on the disabled list.

Davis gets paid at the rate of a $1.5 million salary while in the major leagues and at the rate of a $120,000 salary while in the minors, according to the deal reached Monday. With 112 days remaining in the regular season, his prorated major league salary is $918,033.

Davis hit .268 with four home runs and 25 RBI for Triple-A Round Rock, then was released Sunday.

The 29-year-old played for Oakland last season, hitting .229 with three home runs and 20 RBI. He had 32 homers for the New York Mets in 2012.

Chris Parmelee was the latest Yankees first baseman to go on the DL, joining Mark Teixeira, Dustin Ackley and Greg Bird. Rob Refsnyder has been starting at first after moving over from second base. Backup catcher Austin Romine also can play first.

New York designated right-hander Layne Somsen for assignment to open a spot for Davis on the 40-man roster and cleared a spot on the 25-man roster by optioning right-hander Chad Green to Triple-A Scranton/Wilkes-Barre after Sunday’s game.

METS: Manager Terry Collins has been cleared to leave a Milwaukee hospital and planned to return to New York and be back in the dugout for Tuesday night’s game against the Pittsburgh Pirates.

The 67-year-old Collins, the oldest manager in the major leagues, felt sick before Sunday’s game against the Brewers and was held overnight at Froedtert Hospital in nearby Wauwatosa.

New York said Monday that Collins was examined by Dr. Brian-Fred Fitzsimmons, that tests were negative, and that he had been cleared to fly home.

BRAVES: Left-hander Eric O’Flaherty was put on the 15-day disabled list because of a right knee strain.

He is 1-3 with a 6.52 ERA in 27 games.
