Selby was a three-year starter at Randolph-Macon College who piled up strikeouts in his junior year.  After making 14 starts total in his first two seasons, he made 14 starts and one relief appearance in 2018, with a 2.60 ERA and 126:30 SO:BB ratio in 97 innings in 2018.  He signed quickly after the draft.  After the Pirates signed him, he was sitting in the low-90s, while also throwing a slider and curve.  By 2019, he was sitting at 94-96, at least early in starts, while relying on the slider and a change, with the curve as a fourth pitch.  By 2022 he was reaching the upper-90s.

R+:  1-3-0, 4.15 ERA, 1.24 WHIP, 47.2 IP, 3.0 BB/9, 7.7 K/9

Selby pitched in the Bristol rotation.  He was moderately effective, with a reverse platoon split; he held left-handed hitters to a .573 OPS, but right-handed hitters put up an .812 OPS against him.

A:  6-3-0, 2.97 ERA, 1.11 WHIP, 88.0 IP, 2.8 BB/9, 8.9 K/9

The Pirates sent Selby to Greensboro in mid-May and he spent the rest of the season in the rotation, until he was shut down in mid-August.  He got through 5-6 innings in 12 of 17 innings and never threw fewer than four.  Opponents had just a .613 OPS against him and he had no platoon split.


Right after baseball shut down due to the pandemic, Selby had Tommy John surgery.

A+:  3-1-6, 4.37 ERA, 1.24 WHIP, 59.2 IP, 5.3 BB/9, 10.1 K/9

The Pirates used Selby in relief in his return from Tommy John.  He struggled early, walking exactly a batter an inning and posting an 8.53 ERA the first two months.  After that, he walked 3.5 per nine innings and had an ERA of 2.43.  The Greensboro ballpark hurt his numbers:  He had a 5.50 ERA, five home runs allowed, and .773 OPS allowed at home.  On the road, those numbers were 2.66, two and .370.  Selby also had a big platoon split, holding right handed hitters to a .503 OPS, while left-handed hitters posted an .803 OPS.

AA:  2-2-8, 2.20 ERA, 1.26 WHIP, 32.2 IP, 3.9 BB/9, 11.3 K/9
AAA:  0-1-0, 3.00 ERA, 0.67 WHIP, 3.0 IP, 0.0 BB/9, 6.0 K/9

Selby opened the season with Altoona and got off to a very good start, but in mid-May went out for two months with an unknown injury.  He had a few subpar outings after returning, then pitched well the rest of the season, including three outings with Indianapolis.  Selby kept his walk rate at manageable levels and continued to miss bats.  He had no real platoon split.  The Pirates sent him to the Arizona Fall League to make up for the missed time.

Selby is eligible for the Rule 5 draft for the second time.  The Pirates could gamble that his recent injury history will dissuade anybody from selecting him, but he’s got more upside than nearly any of the multitude of waiver claims that have flooded the Pirates’ 40-man roster in the last couple years.
