Curtis Granderson was slated to start in left field for the Yankees against the Nationals in Viera, Fla., but the game was called for rain while the team was traveling across the state.

Though Granderson likely will be Joe Girardi’s everyday center fielder, the manager is intrigued to find out if Granderson can handle left.

“I want to see how he reacts to balls in left,’’ said Girardi, who makes out the lineup cards with his coaches five days in advance and didn’t know if Granderson will play left in one of the two games today against the Tigers (away) and Orioles (home). “It’s a different angle and the ball will go somewhat a different way.’’

The evaluation process is based on what type of action Granderson gets in left.

“If you don’t get a lot of testers it’s gong to be hard to tell,’’ Girardi said.

Granderson’s “I’ll Do Whatever Asked’’ attitude enables Girardi to get a look at him in left knowing the player isn’t griping.

“It makes it real easy when you have players who do what they ask them,’’ Girardi said. “That shows you they check their egos when they come into the clubhouse.’’

Granderson took some bad routes to balls late last year and the Yankees may have a reason for it: Comerica Park.

“We saw that Detroit’s center field is one of the toughest center fields to play,’’ Girardi said. “We have every stat available (and) it wasn’t necessarily Detroit center fielders.’’
