Hitters had an .890 OPS against Butler the *first* time through the order last year, he walked a couple fewer guys but it's also harder to walk guys when all hitters are hitting .328 (!) against you. The point here is not that Butler is terrible, I think he's potentially a very nice find. The point is that in all of these cases you're looking for improvement beyond what they've done thus far. Butler has gotten shelled in MLB and been effective with weak peripherals in AAA. Montgomery has been effective with weak peripherals in MLB. If you start Montgomery you can keep Butler in AAA and have both being treated as SP for potential future seasons. If Montgomery struggles you can always turn to Butler too. But by starting Butler you're continuing to inch the door shut on Montgomery starting, because in the next few weeks he's not going to be capable of throwing enough IP to be considered for the 2018 rotation. It continues to mystify me that the front office talked up Montgomery as a future starter for the entire 2nd half of the season, Maddon trusted him in the playoffs more than Rondon and Strop, and now they won't let him have a role beyond next-gen Travis Wood even though there is ample opportunity. I have extremely high regard for their evaluations of pitchers, but in this case I have a hard time understanding why they aren't giving Montgomery at least the briefest of opportunities to fail out of that role. Butler just got off the DL for an ankle injury too and hasn't been lighting AAA on fire, so it'd be trivially easy to justify. Well, Monty's role is becoming one of the biggest x-factors a pitching staff can have these days. I get where you're coming from, I also want Monty to get a shot at the rotation, and coming into this year, I had him locked in for 2018. But that role, that bridge guy who can save the pen after a SP gets shelled or pushed out early, and pitch multiple innings, is really invaluable. Especially right now as half of our rotation is shaky and nobody is pitching deep into games, they feel like they're gonna need that bridge guy probably often. So they don't want to lose that weapon. But honestly I think with those 2 as SP you can expect probably similar results, with maybe a slight lean in Monty's favor. Something like a 1.5 KBB and 5 innings at best of hopefully decently suppressed contact and likely a couple runs. So I think they figure they'd rather get that and still have their multi-inning guy who they can count on and have needed quite often in the early going. But I agree and want Monty to get his rotation shot. Maybe as the 1-4 settle in and hopefully start going deeper into games, we won't have such a dire need for that bridge role and can afford to take that chance. For now they probably prefer stopgaps for the 5th spot. Sent from my SM-N900T using Tapatalk
