Roby was placed on the 7-day injured list at Double-A Frisco on Tuesday. He left Friday's game due to an apparent shoulder injury, FanSided.com reports.
Roby had some prospect buzz after posting a 2.45 ERA with a 14.3 K/9 in 2022 at Low-A. He took a step back last year with a 4.73 ERA and 10.9 K/9, but he still had strong strikeout rates. He'd been displaying a decent strikeout rate this year at Double-A with a 4.68 ERA and 9.6 K/9 in 42.1 innings before the injury.
