O’Reilly was a swing man as a freshman for Rutgers and stayed in the rotation for his last three years.  His performance didn’t vary much from year to year, apart from his walk and K rates both dropping steadily.  His ERAs over those last three years were 5.23, 5.87 and 5.32.  His walk rate dropped from 4.0 to 2.9 and his K rate from 6.3 to 4.5.  He got hit fairly hard throughout.  When the Pirates signed him, he was a ground ball pitcher who threw 89-90, topping out at 92 MPH, with a solid changeup and a 12-to-6 curve.  By 2019, though, he was sitting in the mid-90s as a reliever.  The Pirates signed him as a non-drafted free agent.

R:  0-1-0, 13.50 ERA, 2.50 WHIP, 2.0 IP, 0.0 BB/9, 0.0 K/9
R+:  2-1-1, 5.33 ERA, 1.34 WHIP, 25.1 IP, 4.3 BB/9, 7.5 K/9

O’Reilly pitched twice in the GCL and then moved up to Bristol.  He got into a dozen games there.  All of his pitching came in relief.  He had gopher ball problems at Bristol, allowing one every five innings.

A:  1-2-3, 2.15 ERA, 1.53 WHIP, 29.1 IP, 3.1 BB/9, 5.2 K/9
A+:  1-0-2, 0.47 ERA, 1.05 WHIP, 19.0 IP, 2.4 BB/9, 6.2 K/9
AA:  0-0-0, 0.00 ERA, 1.00 WHIP, 1.0 IP, 0.0 BB/9, 9.0 K/9

The Pirates assigned O’Reilly to Greensboro in early May and he pitched in relief.  The low ERA is misleading; opponents batted .297 against him and over half the runs he allowed were unearned.  A lot of the damage came in two games in which he allowed nine hits and nine unearned runs in two and a third innings.  In July the Pirates moved him up to Bradenton and he pitched better there over nine, mostly multi-inning outings, allowing just one earned run.  He finished the season with one appearance with Altoona.


It may be going too far to call O’Reilly a prospect now, particularly given the low K rate.  He made a lot of progress in 2019 for an NDFA, though, and could open 2021 in AA.
