McGuire was only just claimed off waivers, so the Texas organization evidently intended all along to try to sneak him back through waivers. If he clears, the 28-year-old will presumably take up a place on the depth chart at Triple-A while not occupying a 40-man spot.
Though he has seen MLB action in each of the past two seasons, McGuire hasn’t thrown enough innings to tell us much. But he does have loads of experience in the upper minors, having reached Double-A in his first season as a pro, way back in 2011. Over 335 2/3 innings at the Triple-A level, McGuire carries a 5.09 ERA with 6.9 K/9 and 3.5 BB/9.
