DrB's 2016 Giants Top 50 Prospects: #47 Mac Marshall

Mac Marshall, LHP.  DOB:  1/27/1996.  6'0", 180 lbs.

Rookie AZL:  0-0, 2.57, 7 IP, 14.14 K/9, 6.43 BB/9, GO/AO= 1.44.
Short Season:  0-0, 6.59, 13.2 IP, 11.85 K/9, 6.59 BB/9, GO/AO= 1.25.

Mac Marshall has been on scouting radars since before the 2014 draft.  He was a later round pick by the Houston Astros out of HS, but had his promised over-slot bonus blown up by the Brady Aiken mess.  At first, he enrolled at LSU which would have prevented him from being drafted again for 3 years.  After about a month, he left LSU and enrolled in a JC which made him draft eligible for 2015.  The Giants took him in Round 4.  He showed flashes of brilliance but also inconsistency in throwing strikes.  He got promoted to Salem-Keizer, but was shut down and later re-appeared in Arizona for his last 2 appearances.  It should be noted that 5 of his 15 BB's came in 1 game. It should also be noted that all of this is a very small sample size.

Marshall throws both a 4 seam and 2 seam FB. He generally sits 88-92 with the FB but can crank it up to 94.  One thing I like about him is his best pitch is his changeup that has excellent drop and fade to RH batters.  For most pitchers his age, the changeup is just starting to take shape, if they have one at all.  Augusta would seem to be the logical assignment for him to start 2016, but it may depend on his command in spring training.  Ceiling appears to be #3 SP with ETA 2019 or 2020.  Some analysts rank him higher.  I want to see him show better consistency first.  Again, having 3 young pitchers like Bolivar, Webb and Marshall this low on the list tells you how deep the Giants farm system is, even if you think all 3 should be ranked a bit higher.
