"Jake Lamb had a really good day today," D-backs manager Torey Lovullo said before Friday night's game against the Dodgers. "I heard he was in the batting cage and took BP off a coach. He took ground balls, threw and felt very, very good.
"Tomorrow will be a normal progression, where he does everything like a normal pregame. He'll get on the field, take BP on the field, watch the flight of the ball, and also take ground balls and maybe throw across the diamond as well."
Lamb injured the shoulder April 2 while making a diving catch in foul territory and further aggravated it sliding headfirst into home in the 15th inning of an 8-7 D-backs win. He was diagnosed with a sprained AC joint the next day and landed on the 10-day disabled list.
