Six games into the season and the Mets have used three different leadoff hitters. Evidently, there are answers to be found.

One who should get a longer look is Mike Baxter, who started Saturday and reached base three times on two hits and a walk.

A lead off hitter needs to get on base, and if not then take the count as deep as possible to give the following hitters a chance to learn what they can of the pitcher. Baxter usually runs up the pitch count, and if he plays a full game can see as many as a dozen pitches. That’s an in-game scouting report to those following him in the order.

Little League coaches like to say, “a walk is as good as a hit,’’ and there are times it is the same in the major leagues.

“He takes a base on balls,’’ manager Terry Collins said. “If he was a genuine base-stealer, he’d be dangerous. You look up, and he’s got a .375 on-base. It seems like he’s on first base all of the time.’’

Actually, Baxter’s career on-base percentage is .360, but Collins’ point is well taken. It is an on-base percentage representative of a productive leadoff hitter, as good as they received from Jose Reyes.

The stereotypical leadoff hitter is a base stealer, the kind the Mets enjoyed with Reyes early in his career. However, Wade Boggs didn’t steal many bases and hit .321 batting leadoff in over 900 games in his career.

They all can’t be Rickey HendersonLou Brock or Maury Wills.

Although the game has changed and there isn’t an emphasis on base stealing as there once was, the basic fundamental of a lead off hitter has always been the same, which is get on base to set the table for the run-producers.

Kirk Nieuwenhuis was penciled in as the leadoff hitter going into spring training, but has a propensity for striking out. He is still very much a work in progress. Other candidates Collin Cowgill and Jordany Valdespin never had full seasons as a starters.

Cowgill has homered twice and if he continues to flash power he might be needed lower in the order. Valdespin is fast, but can be an out-of-control free swinger. He doesn’t figure to last long at that position, and as a defensive liability, probably won’t get many starting opportunities.

Baxter has a decent glove – Johan Santana wouldn’t have his no-hitter without him – but has never had a full time chance.

So, as long as Collins is searching for answers, Baxter is worthy of an opportunity.
