SF Giants: Complete grades of their 2021 MLB draft class

SF Giants 2021 MLB draft grades
Round 9 (266th): Mat Olsen, RHP, Central Arizona Junior College
Round 10 (296th): Vaun Brown, OF, Florida Southern
Round 11 (326th): Donovan McIntyre, OF, Marian Catholic HS (IL)

Mat Olsen got three years at the junior college level and took a huge step forward this spring. He struck out 133 batters in 88.2 innings against 30 walks and posted a 2.13 ERA. Committed to Arizona State, the Giants will likely give him an above-slot bonus to keep him away from the Pac-12. As I reached out to more industry sources, Olsen seemed like a prime candidate to breakout next year, reportedly touching 97 mph with his fastball alongside a repeatable delivery and sharp curveball.  I’d heard his stuff was relatively average, but he made up for it with pitchability. It may look like the Giants are paying a premium now, but they think they are buying low on someone who could have ended up going in the first couple of rounds with a strong showing for the Sun Devils.

Not ranked on virtually any public draft boards, Vaun Brown is a classic senior sign. A fifth-year senior out of Division-II Florida Southern, Brown saw a huge surge in power this spring, hitting .387/.462/.793 with 13 homers in 26 games. He carried that strong performance over into the Florida Collegiate Summer League but still had concerning strikeout and walk rates given the competition he played against. He’ll likely receive a bonus around $25,000 and hope to make an impression in his pro debut.

Donovan McIntyre will likely receive a bit of the slot pool savings the Giants accumulated on the first two days of the draft. Committed to Kent State, McIntyre is mostly known for plus speed and a projectable body. He has not recorded particularly high exit velos, but he drew interest from the Chicago White Sox, Tampa Bay Rays, and St. Louis Cardinals leading up to the draft as well.

Grade(s): B-
