March 18.10: Perez tries to take another step vs. Marlins.

Oliver Perez is left-handed with 90-mph. plus heat. He’ll keep getting chances. When he’s on, as he was last Saturday against Detroit with four hitless innings, he ignites the imagination.

Then again, when he’s the Bad Ollie, he reduces those in the Mets’ dugout to a bunch of babbling, head-scratching messes. Jerry Manuel once said the Bad Ollie kept him on the top step of the dugout ready to spring out.

Perez threw strikes and spotted his pitches against the Tigers, and the Mets want to see more of that tonight against Florida. The Mets continue to hang with Perez because of his high ceiling for potential, which is greater than John Maine or even Mike Pelfrey.

Perez’s command was good in his first two starts, traceable to a consistency in his footwork mechanics that resulted in a comfortable release point.

“It seems so easy when it all works,’’ pitching coach Dan Warthen said.

When Perez has an idea where his pitches are going he becomes more focused and relaxed. The anxiety is gone.

It seems like a little thing, but in the Detroit game Perez cruised and retired his first eight hitters, but then walked the next two. The wind kept Carlos Guillen’s ball in the park. The next inning, Perez regained his focus and set the Tigers down in order.

There are dozens of games when those circumstances produced a different scenario.

It’s only spring, but it beats what we’ve seen before.

Beltran making progress: Carlos Beltran, who’ll open the season on the disabled list following knee surgery, is encouraged by his rehab.

“I’m doing good,’’ Beltran told ESPN Radio. “I come to the ballpark every single day, rehabbing, to try and put myself in the best condition, so when it come time for me to start playing baseball I can go out there and do what I know I can do.’’

Here’s tonight’s batting order vs. Marlins:

Angel Pagan, CF
Luis Castillo, 2B
David Wright, 3B
Mike Jacobs, 1B
Jason Bay, LF
Jeff Francoeur, RF
Alex Cora, SS
Henry Blanco, C
Oliver Perez, LP

Followed by Pedro Feliciano, Hisanori Takahashi, Pat Misch, Ryota Igarashi and Francisco Rodriguez.
