Gattis underwent a physical with the Astros on Wednesday, USA Today's Bob Nightengale reports. Nightengale cites Houston as one of three teams "aggressively pursuing" Gattis. Although the Braves have planned to move Gattis to left field, he would presumably be a catcher for the teams pursuing him. It in any case remains unclear whether the Astros or the other two teams are able and willing to meet Atlanta's asking price.
