"Definitely good to get back out there on a big league mound for sure," said Gilmartin, who entered with 66 career Major League appearances. "Didn't really do a good job of getting ahead of hitters. I struggled with that all day long, but I was able to make pitches when I needed to and get outs."
The O's signed the 28-year-old Gilmartin in mid-July, and he had been pitching at Triple-A Norfolk, where he posted a 3.14 ERA over 14 1/3 innings. A former Mets Rule 5 Draft pick in 2015, Gilmartin has struggled to replicate that season's effort in which he compiled a 2.67 ERA in 57 1/3 innings.
Prior to Norfolk, Gilmartin logged 46 1/3 innings over 24 outings (six starts) for the Cardinals' Triple-A affiliate, where he had a 4.66 ERA before being released.
