Spears is a big framed lefty who was a starter for three years at Miami of Ohio.  He struggled the first two years, but saw some improvements during his junior year, posting a 3.84 ERA in 77 innings, with an 82:37 K:BB ratio.  He had control problems throughout his college career, and while they didn’t disappear during his junior year, he made progress.  He also improved his strikeout totals in his last two years.

Spears throws 89-93 MPH, although the large frame should give him the capability of throwing harder.  He also throws a changeup, which gets average grades, along with a slider that’s his out pitch.  He’s working on a cutter.  Spears signed for the slot amount.

A-:  1-6-0, 6.07 ERA, 1.72 WHIP, 43.0 IP, 4.0 BB/9, 6.3 K/9

Spears spent his debut season in the Morgantown rotation.  He mostly struggled, with poor walk and K rates, and opponents batting 322/400/462 against him.  He was effective against left-handed batters, who had a .690 OPS against him, but right-handed hitters battered him for a .929 figure.


Spears did not have a good debut, but the Pirates thought he’d made progress during the off-season.  He was slated to join the starting rotation at Greensboro, but suffered an injury lifting weights and then re-injured it.  He had shoulder surgery, which cost him the entire season.

The Pirates will probably give Spears a shot at Greensboro in 2020 if he’s able to pitch.
