With each home run he allows, with each ugly loss he suffers, it becomes easier to see and harder to deny: Johan Santana has been in a funk since his June no-hitter.

The longer his malaise lasts, the more concerning it becomes for the skidding Mets, who will meet today to figure out what to do about their struggling ace.

Santana allowed six runs for a third straight start, losing 7-6 loss to the Dodgers last night. His three-inning outing was the second-shortest of his career, and it wasn't short enough for the 30,806 at Citi Field, who were calling for the hook long before that.

The left-hander allowed seven hits, including home runs by Matt Kemp and Luis Cruz, and a four-pitch, bases-loaded walk. Afterward, Santana (6-7) called it a slump, and manager Terry Collins talked about skipping a start. Collins also refused to rule out the disabled list.

It's an ominous sign for a pitcher who has been downright poor since throwing a career-high 134 pitches in his June 1 no-hitter.

"That no-hitter stuff was a long time ago. I don't think that has anything to do with it," Santana said. "It's just that I'm going through tough times. Call it a slump or whatever it is. I'm just going through tough times. That's about it. I'm OK.

"I'm [just] not able to execute the way you're supposed to. I'm not my best right now. I'm not executing my pitches, I'm not commanding the fastball.

"I'm just going through a tough time, that's all it is. Call it whatever. They've been swinging the bat pretty good, but I'm not on my game right now, I think. I've just got to execute better pitches and command my fastball better, all my pitches, and compete. I'm not doing that right now. A couple times where I got behind in the count and threw the ball right there and they put good swings on it.''
