SEATTLE - Mark Teixeira hit his 15th homer of the season Monday night, a grand slam against Felix Hernandez that helped send the Yankees on their way to a 7-2 victory.

The only thing more surprising than the Bombers beating up on King Felix, after losing three of four in Oakland, might be the start Teixeira has gotten off to. Just don't tell that to Teixeira.

"Nothing really surprises me, good or bad, in baseball," said Teixeira, who leads the club in homers, RBIs (39) and slugging (.566). "There's some weird stats out there and it's still early . . . If I stay healthy, I know what the numbers are going to look like at the end of the year."

But few, maybe outside of the first baseman, thought he'd be this healthy two months in. Once among the most durable players in the sport, the 35-year-old has not appeared in more than 123 games since 2011. There was the right wrist surgery that cost him pretty much all of 2013, the rest of the missed time has been due to a variety of nagging injuries.

But those have been missing to this point and the production has followed.

"Just very thankful for the health," Teixeira said. "The first two months have been so far, so good, but I want to continue it."
