Teixeira takes BP, return in one week possible

NEW YORK -- Yankees first baseman Mark Teixeira, who hopes to be activated from the disabled list when he is eligible in one week, took batting practice on the field Sunday prior to the team's game against the Red Sox.

Teixeira has been on the DL since straining his right hamstring in an April 4 game against the Blue Jays in Toronto. The earliest possible date that he could play is April 20, against the Rays at Tropicana Field.

"He is hitting on the field today, which is, to me, a really good sign," Yankees manager Joe Girardi said. "He did some light jogging on the field yesterday, which is good. I don't imagine it will be a whole lot longer, as long as he continues to progress running."

Yankees closer David Robertson, who is on the disabled list with a left groin strain sustained on April 7, could be activated on April 22 against the Red Sox in Boston.

"He's doing great, too," Girardi said.
