PORT ST. LUCIE, Fla. (CBSNewYork/AP) — New York Mets pitching prospect Jenrry Mejia returned to camp Friday and can resume baseball activities after being diagnosed with a hyperactive thyroid gland.

The 23-year-old flew to New York this week for tests following his spring training physical. He has been advised by doctors not to eat seafood, which is rich in lodine, but he does not have to take medication.

“Everything is doing great. Everything is going well,” said Mejia, expected to start the regular season at Triple-A Las Vegas. “They said everything is looking great and I can do every activity, but don’t eat fish. It’s like Jose Reyes.

“They said (the thyroid) is too quick, but it’s normal right now. They don’t want me to make it faster.”

Reyes, a former Mets shortstop, was diagnosed with hyperthyroidism during spring training in 2010 and missed the first five games of the regular season.

It’s been a spring training of delays and setbacks for Mejia, who went 1-2 with a 5.63 ERA in five appearances for the Mets last season. He appeared in 33 games for the Amazin’s in 2010, posting a 4.62 ERA in 39 innings pitched.

He reported to camp more than a week later than expected due to visa issues in the Dominican Republic and was roughed up in his lone exhibition appearance, allowing five runs in one inning against the Miami Marlins on Feb. 26.

Do you still believe in this guy, Mets fans? Do you think he’ll ever come into his own? Sound off with your thoughts and comments below…
