To play devil's avocado(since I don't feel particular conviction about him), Keegan has been fine or even good since a poor opening outing: 5 IP, 1 H, 0 R, 6/2 K/BB. His velo is down and that is not a good harbinger, but if he's effective at 90-91 instead of 93-94 then as a short term fill in I don't see a huge issue this soon after everyone got a very good look in ST at all the options. Plus we might see something tick up in an MLB environment, different weather, etc. Not gonna bat an eye if he's here to pitch in one blowout and then get DFA'd for someone else though.
