"We have kicked it around a little bit," manager Joe Girardi said.
Starting third baseman Kelly Johnson is currently the backup first baseman. Johnson is also the backup second baseman.
Soriano, who will play in the outfield Friday night, will primarily be a designated hitter. However, he could spell Mark Teixeira from time to time during the season. The Yankees do not plan to carry strictly a backup first baseman.
Johnson is scheduled to play first base Sunday. Girardi doesn't know when Soriano might play the position in an exhibition game.
By the way, Girardi also said the Yankees never considered using Soriano at second base. Soriano started his Yankees career as a second baseman.
Changeup: David Robertson incorporated the changeup a little bit last season, but Girardi said that Robertson might throw it a bit more this season.
Moment of silence: The Yankees held a moment of silence to honor Carmen Berra before Friday night's exhibition game.
