Treinen (shoulder) sported a fastball that topped out at 97 miles per hour in a simulated game Wednesday, and he could soon begin a minor-league rehab assignment, Fabian Ardaya of The Athletic reports.
Treinen is on the road with the club in San Francisco, and manager Dave Roberts stood in against him during his sim game. Roberts noted that Treinen hit 97 on the radar gun and that the session went well. He also said that the righty reliever could toss another sim game, but it's possible he heads out on a rehab assignment as his next step.
