State List Talent Ranking: ????
(Stars are listed on a 1 to 5 scale relative to what the state typically produces, with 1 being the weakest)

1. Sebastian Keane, RHP, North Andover (Mass.) HS (BA RANK: 140)
Source: HS • Ht: 6-3 • Wt: 165 • B-T: R-R • Commitment/Drafted: Northeastern

The top prospect in Massachusetts, Keane is a thin, projectable righthander committed to Northeastern. Listed at 6-foot-3, 165 pounds, Keane has plenty of room to fill out and add more strength to a loose, athletic frame. He was up to 94 mph with his fastball last summer, but this spring he’s pitched more in the 90-92 mph range. Keane has three secondary offerings, including a low-80s slider that projects as an average offering and a currently below-average curveball in the upper 70s. He casted his curveball at times last summer, but when he gets on top of the pitch he is able to generate good spin and solid depth. Keane also has a changeup that projects as an average offering. Overall, Keane’s present stuff isn’t explosive, but he has plenty of traits to dream on and has shown good feel for landing his pitches for strikes despite an high-effort delivery that features a slight head whack. He’s a high-upside prospect who has had plenty of high-level scouts in to see him frequently this spring.

2. Sean Mellen, LHP, Northeastern (BA RANK: 387)
Source: 4YR • Ht: 6-5 • Wt: 215 • B-T: L-L • Commitment/Drafted: Never Drafted

A 6-foot-5, 215-pound lefthander, Mellen doesn’t have big stuff, but he’s performed in a big way the last two years as a starter for Northeastern and posted a 2.76 ERA this spring through 13 starts and 78 innings. Mellen’s fastball is a below-average offering in the upper 80s and he has two below-average breaking balls, but he generates a surprising amount of whiffs (99 strikeouts to 34 walks this spring) thanks to a deceptive, funky delivery. Mellen’s changeup is his best pitch, but despite his size and handedness it might be tough to take that profile in the top 10 rounds unless a team thinks more velocity will come as Mellen gets further away from a back surgery last fall.

3. Hunter Bigge, RHP/INF, Harvard (BA RANK: 396)
Source: 4YR • Ht: 6-0 • Wt: 205 • B-T: R-R • Commitment/Drafted: Never Drafted

A two-way player at Harvard, Bigge’s pro future is on the mound, where he has a fastball that’s been up into the 94-96 mph range at its best this spring, with a breaking ball that has a chance to be average. While Bigge’s stuff is solid, he’s always been a bit too hittable on the mound at Harvard, allowing 109 hits over 103 career innings, including his first 10 starts this spring. He’ll need to improve his control if he wants to survive at the next level, as his 34 walks in 59.2 innings this spring (5.13 per nine) is the best rate he’s managed in the Ivy League. Bigge is likely a reliever at the next level.
