SAN DIEGO - Infielder Wilmer Flores has been on a tear since he was demoted to Triple-A Las Vegas. By going 1-for-4 Sunday, he extended his hitting streak to 21 games. During the streak, he's hitting .365 with seven homers and 29 RBIs.
But Mets manager Terry Collins said Sunday that a major-league promotion likely isn't in Flores' immediate future.

"I don't want to bring young guys up here and have them sit on the bench," he said. "I just don't think it's good for their development."
Flores, 22, was promoted earlier in the season, though he played sparingly after shortstop Ruben Tejada got on a hot streak.
Said Collins: "If Wilmer Flores comes, I think he's going to have to play someplace, because I don't think he gets anything out of sitting on the bench playing once a week."
Return of Niese
As expected, Jonathon Niese will come off the disabled list to start Monday night's series opener in Seattle. He has been sidelined since July 6 with a left shoulder strain.
Daisuke Matsuzaka will return to full-time relief duty for the first time since May.
To make room on the roster, righthanded reliever Buddy Carlyle was designated for assignment after Sunday's 2-1 loss to the Padres.
