Trevor Cahill has been effective as both a starter and a reliever.
In his second MLB season, he went 18-8 with a 2.97 ERA and 1.11 WHIP in 196.2 innings with the Oakland Athletics, earning his lone All-Star selection and finishing ninth in AL Cy Young voting.
He topped 200 innings in each of the next two seasons before injuries cost him time, and he eventually transitioned into a relief role.
The 32-year-old has shuffled between roles in recent seasons, serving as a useful middle reliever with the Chicago Cubs in 2016 (50 G, 4 HLD, 2.74 ERA, 9.0 K/9) and a quality starter in his second go-around with the Athletics in 2018 (20 GS, 7-4, 3.76 ERA, 1.19 WHIP).
