Midseason Relief Pitcher Rankings Analysis
Tier 1
Craig Kimbrel may have just blown his first save at Fenway Park, but he’s still performing like an absolute warrior out on the mound with an insane 16.25 K/9 and Major League-leading 1.04 FIP. The strikeouts give him the edge -- in my opinion -- over Kenley Jansen, whose 13.5 K/9 is still incredible but just not as insane. They both make Roberto Osuna’s 1.46 FIP, 12.09 K/9 and 0.77 BB/9 rates look pedestrian, but please believe he’s worth top-tier consideration.
Tier 2
Maybe I shouldn’t have this much faith in Zach Britton, but I trust him to return to form more so than Aroldis Chapman. Kyle and I practically have the two flip-flopped across a 70-slot gap, but I’ll take Britton’s sinker over Chapman’s heater -- especially now that Joe Girardi has hinted that maybe Chap’s postseason run with the Cubbies is causing him some serious wear in 2017.
Meanwhile, folks like Wade Davis and Edwin Diaz are doing their thing, as others like Raisel Iglesias, Felipe Rivero, Greg Holland and Corey Knebel have come from far down on the ADP charts (or from the unranked territory) to provide stellar value. I’m lower on mostly everyone here as I just have a large amount of hatred for non-elite RPs, though I realize that sort of goes against what rankings are about.
Tier 3
Ken Giles is doing well, though Houston scores too many stinkin’ runs to generate as many save opportunities as their hefty win total might hint at. The Astros’ stopper is sporting a 15 percent swinging-strike rate, which would be impressive if he hadn’t posted a ridiculous 19.9 percent SwStr rate last season alongside a spectacular 13.98 K/9.
Andrew Miller was just lifted with a “hot spot” so that would jack up Cody Allen’s value in my mind, and I should also be more afraid of Kelvin Herrera and Alex Colome’s lesser skill set (especially in the strikeout and walk departments). But for now, they’re still rather secure in their roles and that goes a long way. I would feel a lot better if I knew that David Robertson would close after being traded, but I’m just not there so the ranking reflects that. The same note goes for Brandon Kintzler down in Tier Five.
Tier 4
Chris Devenski is a tank but I can only go so far for those arms that don’t really have a shot at closing and also are pretty much out of the running when it comes to breaking into the rotation and shining (a la Alex Wood). A.J. Ramos and Addison Reed are plugging along, with Justin Wilson being one of Kyle’s favorites. I’m not entirely sold on him, but I’m not going to hold it against anyone who does considering all that he’s done so far and the lack of any internal threat.
Tier 5
Seung-Hwan Oh carried such high hopes, but he’s been absolutely torched this season and has Trevor Rosenthal breathing down his neck. Brandon Maurer has been excellent and it appears that Brad Hand is drawing most of the trade interest here, though nothing is safe in San Diego. Mark Melancon should be able to recover so I’ll keep on ranking him here -- it isn’t as though I fear Sam Dyson running away with things.
Tier 6
You don’t really want to be relying on any of these guys, with most of them being rather interchangeable with anyone who has an outside shot at the ninth inning. I still hold out hope that Dellin Betances conquers his walk demons, and the aforementioned Chapman fatigue has me thinking that he ends up back in the ninth inning at some point very soon. Matt Bush (and Alex Claudio) are looking alright, and sadly folks like Fernando Rodney, Jim Johnson and Santiago Casilla continue to turn in saves and demand you roster them.
