Gamboa became a minor league free agent after the year, but apparently drew enough interest that the O’s felt compelled to give him a 40-man spot. Last year, he threw 108 2/3 innings of 3.81 ERA ball over 17 starts and two relief appearances in the upper minors. Gamboa managed 8.6 K/9 while issuing 3.8 free passes per nine in the process.
Gamboa was suspended for 50 games last year due to medication for a thyroid condition. He explained to Steve Melewski of MASNsports.com that he was merely taking prescription medication for a thyroid issue, though he acknowledged he had not received a therapeutic use exemption. It would appear that Baltimore believes in Gamboa’s insistence that he was not relying on any substances to prop up his performance.
