Ortiz in Red Sox dugout, wearing heart monitor for weekend

BOSTON -- Boston Red Sox slugger David Ortiz returned to Fenway Park, confident that wearing a heart monitor for a few days will hasten his return to the lineup.

Ortiz held a press conference with team physician Thomas Gill before Saturday's game against the Toronto Blue Jays.

"The most important thing right now is that I have no problem with my heart," Ortiz said. "The doctors told me 'Your heart is fine. We're just going to keep tracking.'"

Ortiz was released from Massachusetts General Hospital on Thursday after tests for heart palpitations.

"I feel good," said Ortiz, who will be examined next week to determine when he can play again. "I might pinch hit today, that's how good I feel."

Dr. Gill said Ortiz will wear the heart monitor over the weekend, and if there was any indication that symptoms returned, "he could push a button to record the event."

Ortiz, the AL leader in homers and RBI, smiled often as he discussed his frustrations with being out of the lineup since Monday after experiencing heart palpitations for the second time in August.

It was unclear whether Ortiz would resume any baseball activities over the weekend.

"It's wait and see," Dr. Gill said.

The Red Sox designated hitter had a normal test after returning from Seattle on Tuesday. Boston ended a nine-game West Coast trip on Wednesday.
