Scouting Report

Scouting grades: Fastball: 60 | Slider: 50 | Changeup: 55 | Control: 55 | Overall: 45

Jefferies answered questions about a shoulder injury during his junior season at California when he came back and pitched well leading up to the Draft. The A's were convinced and took him with the No. 37 pick in 2016. His career in the organization has barely gotten started as he needed Tommy John surgery after just two outings and has logged just two Rookie-level innings since.

Jefferies did participate in mini camp as the 2019 season approached and the ball was coming out of his hand well. His velocity was up to 90-91 mph in bullpen sessions and he'd shown excellent command of his low-90s fastball in the past. His changeup has the chance to be a plus pitch, thrown with terrific deception, and the bottom falls out of the pitch. His slider looks more like a cutter to some and it has more teeth that way, with the A's wishing he would have a little more finish on the end of it to turn it into a better-than-average pitch.

Jefferies was always known as a strike-thrower before the injury, and he got back to filling up the zone in 2019. After good post-surgery progress, he's attacking the organizational ladder in earnest.
