NEW YORK (AP) The New York Yankees have put first baseman Mark Teixeira on the 15-day disabled list because of a bruised right shin, leaving them without a prime power source as they chase Toronto for the AL East lead.

The Yankees made the move before Friday night's game against Tampa Bay. The move is retroactive to Aug. 27.

New York began the day 1 1/2 games behind the Blue Jays for the division lead. The Yankees hold the top AL wild-card spot, four games ahead of Texas.

Minus the 35-year-old Teixeira, the Yankees will likely play rookie Greg Bird at first base. Bird has hit .254 with three home runs and 12 RBIs in 18 games since making his major league debut this season. Alex Rodriguez, Chase Headley and Brian McCann have seen limited action at the spot.

Teixeira leads the Yankees with 31 home runs. He's hitting .255 with 79 RBIs in 111 games.

Teixeira was hurt Aug. 17 when he fouled a ball off himself. He missed a week, returned for one start and then a pinch-hitting appearance on Aug. 26. He hasn't played a full season since 2011 because of injuries.

Right-handed reliever Nick Rumbelow was called up from Triple-A Scranton/Wilkes-Barre.
