View Draft Report
Marshall ranked No. 57 on Baseball America's Top 500 draft prospects list a year ago when he was coming out of Parkview High (Lilburn, Ga.). But he was believed to be strongly committed to LSU and fell to the 21st round, when the Astros drafted him. They made a late run at signing him, but weren't able to reach what would have been a significantly over-slot deal. Marshall didn't stay at LSU, however, opting instead to join his high school teammate Isiah Gilliam at Chipola Junior College. That move enabled Marshall to reenter the draft this year instead of waiting until 2017. He started the season well before a broken thumb sidelined him for more than a month. Marshall largely looks like the same player he was a year ago. His throws his fastball 90-92 mph with a bit more velocity when he needs it, though he'll likely pitch with an average fastball at best on a pro throwing schedule. His changeup is a plus offering with tremendous tumble and his curveball has above-average potential. He has an excellent feel for pitching and fills up the strike zone with his whole arsenal. Listed at 6-foot-1, 187 pounds, Marshall doesn't offer much projection, but as an athletic lefthander with a plus changeup, he still has the look of a future big league starter.

Coming out of Parkview High in the Atlanta suburbs in 2014, Marshall, a 21st-round pick, appeared headed to Louisiana State because the Astros didn't have the money to meet his seven-figure bonus demands. But when Houston didn't like what they saw in No. 1 overall pick Brady Aiken's medical report, they offered Aiken a lesser amount, reopening the possibility for Marshall to sign. The Astros made a hard run at Marshall but didn't sign him, so he headed to LSU. But in September, he transferred to Chipola (Fla.) JC to become eligible for the 2015 draft. He missed six weeks of his juco season with a broken thumb, and after signing with the Giants for $750,000 as a fourth-round pick, Marshall was kept on a conservative innings limit at short-season Salem-Keizer. Scouts have long questioned whether he will be able to handle lengthier outings as a starter. He will touch 94 mph early but usually settles in at 88-91. Marshall's best weapon is a potentially plus changeup with good tumble, but his mid-70s curveball also has above-average potential because he can vary its shape and throw it for strikes. Marshall's delivery has some effort, and he struggled to stay balanced over the rubber and to stay direct to the plate in his pro debut, leading to control trouble.

Marshall comes from a powerhouse program that won the 2012 national high school championship and consistently has produced draft talent, including 2012 supplemental first-rounder Matt Olson and 2013 supplemental first-rounder Josh Hart. The loose, athletic Marshall could continue that streak. After touching 94 mph on the showcase circuit and sitting in the low 90s at some events, he has played at 87-90, touching 92 this spring. Marshall has advanced feel and ability to manipulate two secondary pitches that show at least above-average potential. His changeup is a plus offering with tremendous tumble. He shows the ability to vary the shape of his curveball, shows a good feel for pitching and projects to have at least average control. Marshall throws from a high three-quarters arm slot and can get downhill plane, but his fastball tends to be flatter and he tends to work up toward the higher end of his velocity range, making him more of a flyball-oriented pitcher at the pro level. Marshall has an athletic build but limited physical projection. Both of his parents attended Georgia, but he changed his commitment from the school to sign with Louisiana State.
