Vogt resting at home after being hit by foul tip

OAKLAND -- A's catcher Stephen Vogt remained at home resting during the club's opener against the Astros on Monday, one day after being hit in the groin by a foul tip in a loss to the Mariners.

"Based on the ultrasound yesterday, nothing is fractured or ruptured," manager Bob Melvin said Monday morning. "There was a lot of swelling, so they're going to do another one today to make sure, but he's resting as comfortably as you can rest at this point.

"He won't be here today, and we'll have a better idea in the next coming days when he would be available again."

In Vogt's absence, rookie Carson Blair becomes the backup to Josh Phegley. Blair made his big league debut Sunday as a defensive replacement for Vogt and drew a walk in his first career plate appearance.

Melvin said he would be comfortable giving Blair a start while Vogt is sidelined.

"Usually with a guy like that, you're most concerned with the catching and throwing and receiving part of it, where we saw enough in Spring Training to be very comfortable with that end of it," Melvin said. "At points during the season this year, he's swung the bat very well too."
