Thyroid issue sends Reyes back to New York

Mets shortstop Jose Reyes plans to undergo tests in New York after doctors in Florida discovered a thyroid imbalance, the team said Friday.

Reyes will have tests on Monday and it could take up to 48 after for doctors to receive the results. Reyes is not expected to take part in any physical activity while he is gone.

“We’re going to be conservative,” said Mets general manager Omar Minaya.

The thyroid is a gland in the neck that produces hormones that help control metabolism.

Doctors cleared Reyes to play Friday after he took a follow-up blood test to one conducted during his physical. However, Minaya said team doctors in New York wanted to take a closer look at the speedy infielder and pulled him out of pregame stretching.

“I know he wants to play bad, but he’s going to play enough,” manager Jerry Manuel said after the Mets’ 4-3 loss to the Florida Marlins. “There’s no doubt in my mind that he’s going to play. I know he’s anxious to get out there.”

Reyes appeared in only 36 games last season because of a hamstring injury, which Reyes said has healed. The Mets have discussed moving him from the leadoff spot to third in the lineup while outfielder Carlos Beltran recovers from offseason knee surgery.

Reyes said he felt fine and has not experienced any dizziness, fatigue or any other symptoms of a thyroid problem. He said he was anxious to find out what is happening.

“We’re not talking about my leg, nothing like that, we’re talking about my health,” he said, “so I have to be concerned about it.”

Reyes said this is the first time an imbalance was found in a blood test, and maintained that he does not feel “haunted” by injuries after being summoned to New York.

“I don’t want to say unlucky because leg-wise everything feels good,” he said. “But this is different. We’re not talking about an injury on the field.”

Short hops

Facing hitters for the first time in 17 months, Oakland’s Ben Sheets threw 12/3 healthy innings for the Athletics to start Friday’s 8-7 win over the Milwaukee Brewers in Phoenix. … Joba Chamberlain allowed five runs, three hits and three walks over 1 innings in New York’s 12-7 loss to the Tampa Bay Rays in Tampa, Fla. Slowed by flu-like symptoms this week that cost him 8 pounds, Chamberlain threw just 14 of 33 pitches for strikes in relief of Phil Hughes, whom he’s competing with to be the Yankees’ fifth starter. … Veteran pitcher Jason Grilli and promising rookie Jordan Brown were injured at the Cleveland Indians camp in Goodyear, Ariz. Grilli, a right-hander in camp as a non-roster free agent, had his right leg immobilized as he rode a cart to the trainer’s room after getting hurt during agility drills. Brown was injured while shagging fly balls. Brown, a 26-year-old first baseman/outfielder, won the Triple-A International League batting title with a .336 average last season.
