Yankees 1B Mark Teixeira to retire at end of season

Mark Teixeira is expected to announce his retirement later Friday effective at the end of the season, sources told ESPN's Buster Olney.

Teixeira, 36, is a three-time All-Star and five-time Gold Glove winner. His best season came in 2009, his first with the Yankees, when he hit .292 and finished second in AL MVP voting.

The Yankees have scheduled a 3 p.m. ET news conference about Teixeira, although they did not detail the reason.
