The Mets have signed free agent outfielder Gary Sheffield according to SI.com’s Jon Heyman.

It is presumed that the Mets will pay him the pro-rated portion of the $400,000 minimum. The Tigers are obligated to pick up the rest of Sheffield’s $14 million salary.

“Gary gives us another element in the lineup and he gives us a different intensity, just because of the competitive guy that he is,” Mets GM Omar Minaya said.

Sheffield chose the Mets over the Phillies and Reds because he believes he’ll get more playing time in New York.

“The Mets told him, ‘You deliver, and you’ll play,’ ” a person close to Sheffield said.

Though Mets people have said no promises have been made.

Sheffield should be on a short leash. He’s expected to be a right-handed bat off the bench and maybe get some time in right field but the moment he starts bitching about his playing time Omar Minaya should end the experiment.

The added pop to the lineup will be nice for the Mets, but they don’t need anyone getting in the way of the development of youngsters Daniel Murphy or Ryan Church.
