MET NOTES

SAN DIEGO – Mike Pelfrey is 3-for-3 this season.

Pelfrey, the Mets’ No. 1 draft pick from last year and the team’s top pitching prospect, delivered his third straight strong outing in Single-A St. Lucie on Wednesday night.

The 22-year-old Pelfrey went five innings against Daytona, allowing two runs on five hits with no walks while taking the loss, and struck out five.

The right-hander is 1-1 with a 1.12 ERA and 18 strikeouts in 16 innings so far.

St. Lucie manager Gary Carter said yesterday he believed Pelfrey “topped out at 96 [Wednesday] night.” He said Pelfrey’s pitch count is “no more than 75 right now. That could escalate to 85, but his pitch count was around that [Wednesday].”

Asked about the biggest thing Pelfrey still needs to work on, Carter said, “I guess if anything, it would be consistency.

“He usually is right around the strike zone. I think if there’s one deficiency, maybe it’s from time to time his breaking ball.”

Former Met Mike Cameron was set to play a rehab game yesterday for the Padres’ Lake Elsinore Single-A club. Cameron is out with an oblique strain and told The Post earlier this week that he could potentially play against the Mets in “maybe the last two games or so.”

Entering last night, Kaz Matsui had yet to take his first at-bat of the season, having been sidelined with a right knee MCL sprain. But whenever Matsui has that first at-bat, he will be gunning for his third season-opening-at-bat homer in three years.

In 2004, in Matsui’s first at-bat of the season, he homered off then-Atlanta pitcher Russ Ortiz on the first pitch of the year. Then last year, he went deep in his first at-bat of the season against Cincinnati’s Paul Wilson… Jose Reyes entered last night in a 2-for-18 funk that had dropped his average to .262.
