Athletics' Frankie Montas: Throws bullpen session

Montas (shoulder) felt good after a 25-pitch bullpen session Tuesday and hopes to start during the three-game series against the Astros this weekend, Martin Gallegos of MLB.com reports.

The right-hander had a throwing session Saturday and has now completed a successful bullpen session. The A's have refrained from placing Montas on the 15-day injured list due to the shoulder inflammation to this point, and it appears he's on track to re-enter the rotation without being placed on the shelf.
