The Mets are considering moving Kirk Nieuwenhuis into the leadoff spot, manager Terry Collins said.

The move would be pending how well Nieuwenhuis does at the plate in future games.

The 24-year-old center fielder, who was called up from Triple-A Buffalo after Andres Torres was placed on the disabled list with a strained left calf, went 2-for-4 in his Major League debut on Saturday.

“His past is he can be patient at times,” Collins said Sunday. “There was a consideration about hitting him ninth followed by Ruben Tejada, Daniel Murphy and David Wright. But if I’m gonna do that, why don’t I just lead him off?

“If he starts swinging the bat, I’m gonna have to get Kirk up there earlier.”

• Collins said Johan Santana will throw on Sunday and is on track to make his next start on Wednesday afternoon against Nationals phenom Stephen Strasburg.

Santana, making his first regular season start in 19 months, threw five scoreless innings but came away with a no-decision in Thursday’s opener.

• Ike Davis and Tejada are the only Mets’ regulars who have yet to get a hit. Collins said he isn’t concerned, however.

• The Mets’ best home start was in 2005 when they won their first five games at Shea Stadium.
