Red Sox's James Paxton: Does dry throwing from mound

Paxton (hamstring) played long toss and did some dry throwing from a mound Tuesday, Jen McCaffrey of The Athletic reports.

More specifically, Paxton went through his throwing motion but didn't actually throw a ball when he stepped on the mound. Paxton is progressing slowly but surely from a right hamstring strain, but it's not clear when he might be ready to face hitters or pitch in a game. He's expected to open the season on the injured list.
