TAMPA, Fla. — The Yankees were already trying to gird themselves for a season without a ton of power in their lineup, and then Curtis Granderson stepped into the batter’s box to face the Toronto Blue Jays’ J. A. Happ on Sunday.

In his first plate appearance of spring training, Granderson fractured his right forearm when he was struck by a pitch in the first inning of the Yankees’ 2-0 loss. Granderson, an outfielder, is expected to miss 10 weeks, an absence that will extend into May. The Yankees’ regular-season opener is April 1.

“Well, it’s not what you want,” Manager Joe Girardi said. “We have plenty of time to figure out what we’re going to do. I mean, Grandy’s not a bat that you’d say is easy to replace, but we’re going to find a way.”

Granderson, a three-time All-Star who joined the Yankees in 2010, led the team last season with 43 homers and 106 runs batted in. He started Sunday’s game in left field, part of an experimental switch with Brett Gardner, who played center.
