Source: Marcum visits doctor

NEW YORK -- Mets starter Shaun Marcum visited the team doctor on Tuesday, according to a source.

Marcum started Monday against Arizona, and was seen in the dugout rolling his neck and pointing to his shoulder area. He told reporters after the game that he was fine.

Marcum was evasive following the Mets' 9-1 win over Arizona on Tuesday when asked whether he underwent an MRI.

"That's for me and the club," Marcum said. "I don't know why you guys think you need to know everything."

Marcum reiterated Tuesday that he feels fine, and said as far as he knows he's still scheduled to make his next start on Saturday against Milwaukee.

The New York Post reported Tuesday that the Mets had considered placing Marcum on the disabled list, as the team called up reliever Gonzalez Germen, but the Mets instead demoted infielder Zach Lutz. The Mets did not announce the move until approximately 6 p.m., an hour before first pitch.

Marcum was sidelined during spring training and at the beginning of the season as he dealt with neck and shoulder pain that ultimately required a shot to calm down. He's been a disappointment thus far, as he's 1-9 with a 5.03 ERA. He signed a one-year, $4-million deal with incentives this winter.

If Marcum ends up being sidelined, Mets manager Terry Collins has indicated that reliever Carlos Torres would step into the rotation. Torres started for Triple-A Las Vegas, but his longest outing for the Mets thus far is 2 1/3 innings. He's pitched quite well for the Mets this season, as he's 0-1 with a 0.84 ERA.

The Mets currently have one starter on the disabled list in Jon Niese (shoulder), who has a partial tear in his left rotator cuff. Niese is scheduled to undergo a follow-up MRI on Thursday.
