Weathers (finger) is expected to throw three innings and around 50 pitches in a live batting practice session Tuesday, MLB.com reports.
Weathers looks set to increase the volume of his throwing after he tossed two innings and 35 pitches in his first live BP session Friday. The southpaw has been on the shelf since June 8 with a left index finger strain but looks poised to return from the 60-day injured list at some point in the second half of September.
