Selected by the Miami Marlins in the 16th round of the 2014 MLB Draft, left-handed pitching prospect Scott Squier spent the full 2017 season with High-A Jupiter, where he appeared in 28 games (26 starts), throwing 132.0 innings and finishing 5-9 with a 3.82 ERA. In that span, the University of Hawaii product allowed 143 hits (9.6 H/9) and 26 walks (3.6 BB/9) while striking out 102 batters (5.4 K/9) for the Hammerheads. After the season, the Marlins sent the 25-year-old lefty (DOB: September 17, 1992) to the Arizona Fall League, where he pitched for the Salt River Rafters across October and November.
Scott Squier is a pretty conventional lefty, offering a three-pitch mix and playing primarily off his fastball to draw weak contact without wipeout stuff. Good control and some command have kept him a starting pitcher for much of his career, but 2018 will mark his fifth season in pro ball and it’s time to push into the upper minors and establish a presence there against better hitters. Below, Baseball Census has a full Scott Squier scouting report based on our views at the Arizona Fall League, including game video, tool grades, projection notes and more on the Miami Marlins left-handed pitching prospect.

Scott Squier Scouting Report — Notes, Analysis & Projection
Scott Squier was an interesting choice to send out to Salt River, considering he threw more than 130 innings during the regular season and is far from being on any prospect list — though that likely says more about the Miami Marlins and how they see the AFL season than it does Squier himself, who no doubt benefitted from the opportunity to face some very good, young hitters.
But reality comes quick now, with the lefty already 25 years old. Having only just graduated the High-A Florida State League in 2017, he must move quickly from here if the Miami Marlins are to take him seriously as a potential big league contributor. For me, little of what Squier did at the Arizona Fall League last month would suggest that he’ll be a significant piece in the club’s imminent big league rebuild over the next few years. He’s hittable (FSL opponents batted .280 against him in 2017) with middling stuff and very little margin of error considering his lack of overpowering velocity or wipeout pitch life, and he’ll find it a struggle to survive in the upper minors without pinpoint command to dot his stuff corner to corner right at the knees.
Assuming modest improvements in time — even though, at 25, Squier may be close to final form — and knowing he’s a lefty with feel for three pitches, there’s still a shot yet for him to function in an up-and-down role in the coming years. Short of a magic injection of raw pitch life out of nowhere, though, his in-zone command must markedly improve to the point where he’s living at the knees, because there’s just not much margin of error anywhere higher in the zone. Scott Squier is a consistent strike thrower who attacks hitters with three pitches and has a solid minor league track record, though, and that’ll count for something as he makes the transition into the upper minors.
Overall Future Potential (Future Value): Underwhelming arsenal with command inconsistencies; likely relief future in low-leverage work; possible spot/emergency starts in an up-and-down role (40)
MLB ETA: 2019
