Throughout 2014 and 2015, the Royals bullpen was out of this world. Looking back, it shouldn't be a shock to anyone that Kansas City was able to dominate the way they did and shut down opposing teams in the postseason. The honest truth is that the Royals pen of that era was a 'once in a lifetime' group that we might never see again. Sure, it feels like every team in baseball is trying to copy the Royals' blueprint (Hello, Rockies!) but who knows if we see that level of domination in both the regular season AND the postseason again.
But what that group taught us is that success can be fleeting. The last two years, the Royals bullpen has been a shell of those playoff teams when the honesty of the situation is that the Royals had slid back into the norm. Many fans expected dominance all the time, not realizing how irregular the numbers were that those bullpens were putting up. The truth? The Royals bullpen the last two years has been a very average group, or in other words...normal.
The numbers in 2017 speak of just how average they were: 3.9 fWAR, 4.24 ERA, 4.14 FIP, 20.4% strike out rate, 10.0% walk rate. These numbers placed the Royals pen in either the middle of the pack or closer to the bottom of the American League. While the pen did post a 4.20 WPA last year (good enough for 5th best in the AL), they also put up a 1.64 RE24, putting them down to 10th in the league. In other words, while this group had some positives, they had just as many (if not more) negatives to cancel out the good they were doing.
So what does the bullpen have moving forward? To be honest, the pen is in a bit of disarray. Scott Alexander and Joakim Soria have been traded. Kelvin Herrera has been mentioned as a trade possibility and logic will tell you that the Royals should look further into dealing him. He is coming into the last year of his contract and will be making a substantial amount of money for a reliever on a rebuilding team.
Herrera is the interesting case, as he is coming off of a very roller coaster season. Herrera saw his strike out rate decline (30.4% to 21.6%), his walk rate shoot up (4.2% to 7.7%), and his home run to fly ball rate took a step up as well (10.0% to 14.5%). Many expected his transition to the closers role to be an easy move, while instead it turned into a nightmare and he had been displaced by the end of the season.
So did anything go right for Herrera? Not really. His numbers almost across the board went in the opposite direction and the only (somewhat) positive to find was an increase in his velocity. Almost all across the board was an increase: his sinker, slider, change-up, and curve all saw an uptick...except for his cutter, which took a dive from averaging 96 MPH to 90.4 MPH.
The argument could be made that this could have very well been his downfall, as Herrera was using the cutter at a greater rate last year, from 0.1% to 8.1%. He was also using his fastball at a higher rate (56.4% to 66.9%) and while it is a plus pitch, it has always been his ability to mix in his off-speed stuff and breaking balls that pushed his success. Those off-speed pitches were used less in 2017, and a re-focus on their usage could bring success to Herrera in the upcoming year.
All that being said, it feels like the time to deal him. Herrera could see a pay increase from arbitration and with the Royals looking to rebuild, there is not much need to keep him around. He will be going into his age 28 season and it would make more sense to deal him now and continue rebuilding the pen.
So how does the rest of the pen shake out? Brandon Maurer and Ryan Buchter (two of the pitchers acquired from San Diego over the summer) will be back for their first full season in Kansas City and one would have to think their numbers would improve upon their short stint in KC so far. Maurer is an interesting option, as his plus fastball can be a difference maker. A number of scouts have suggested that Maurer would be better suited in the set-up role, (rather than as the closer he was in San Diego) and if he can command his control, we could see improvement from him in 2018.
There are a number of other arms that could be interesting options for the pen this year. Kevin McCarthy had a solid rookie season and Andres Machado could be an interesting arm if he isn't in the minors as a starter. Brad Keller and Burch Smith were acquired in trades after being picked in the Rule 5 draft and could add some depth to the back-end of the pen. Wily Peralta was signed earlier this offseason and while he has struggled the last couple seasons, he still has an electric fastball and could be a pet project for new pitching coach Cal Eldred. Scott Barlow is another interesting option that was signed by Kansas City this winter and could be a nice fit for the Royals in middle relief :
“Today, Barlow’s heater sits in the low 90s, but his out-pitch is a plus-slider which normally comes in between 78 and 82 MPH. He also throws a curve in the low 70s and changeup in the low 80s to compliment his off-speed arsenal.”
Barlow is also on the 40-man roster, so he should be given a bigger opportunity to secure a main roster spot this spring.
A number of minor leaguers could also see action this year, names like Tim Hill, Eric Stout and yes, Kyle Zimmer. Zimmer could be an intriguing option out of the pen if (and stop me if you've heard this one) he can stay healthy, while Josh Staumont could also make the case for a job if he can harness some of his control issues. The one name I expect to hear from in 2018 is Richard Lovelady, who compiled a great season in 2017. John Sickels of minorleagueball.com had this to say about Lovelady:
10th round pick in 2016 from Kennesaw State; 1.62 ERA with 77/17 K/BB in 67 innings between High-A and Double-A; fastball up to 96, good slider, usually throws strikes, command and stuff good enough to avoid LOOGY work, might get to close games eventually if command holds; as usual, rating/grading relievers is problematic due to difficulties in valuation but he should be a good one.
There are options in the minor league system and a number of arms could be given opportunities in the upcoming season.
For a team that is not going to be a contender, I almost lean toward the Royals going with a bullpen by committee this season. This would allow them to see what they have as the season progresses and I'm a proponent of using your best pitchers in the best situations. The closer role in general feels outdated and it would be nice to see the Royals shuffle their pitchers around according to what is going on with the game. The reality is that Ned Yost appears to prefer having set roles for his relievers and outside of 2015 and the postseason, has used them in their roles. There was some shuffling late last year, but that felt more like a reaction to Herrera's struggles and the injuries they had been dealt. So while it would be nice to see a more "hands on deck" approach, we shouldn't count on seeing it in the near future.
The bullpen in its current state feels a bit weak but they still have time to work on that this offseason. There are a number of options on the free agent market this winter, but few that really pop out. Drew Hutchison interests me, as he could be a nice reclamation project and could see an uptick in velocity, as he would be shifting from being a starter to a reliever. Moore could easily sign a few guys like that to minor league deals, bring them into camp and see what they can do. The options are endless right now and it would be smart for the team to think outside the box. The focus was once on building a better bullpen to compensate for a weak rotation. It might be time to take that route once again.
