New York Mets reliever Pedro Feliciano wore a heart monitor while pitching and reported no problems or discomfort during his first spring training outing.

Feliciano threw one inning against the Miami Marlins in a "B'' game on a practice field behind Roger Dean Stadium. He allowed one run — on Ben Lasater's home run — hit a batter and struck out one.

Feliciano was diagnosed last week with a rare genetic condition called left ventricular noncompaction. The condition results from the failure of myocardial development from birth. Feliciano said he never thought about the heart monitor while in the game.

The 36-year-old left-hander missed the past two seasons because of a shoulder injury.
