BP Annual Player Comments

YearComment
2016 Already a dominant force in the late innings, Herrera stepped up his game last September when Greg Holland's injury forced everyone in the Kansas City ‚Äėpen to move one peg up the pecking order. His triple-digit heater and devastating changeup were already racking up plenty of strikeouts and even more weak groundballs, but the slider he unveiled late in the season rendered him virtually unhittable. Herrera struck out over 40 percent of the batters he faced in the playoffs and posted a 61 percent groundball rate, holding batters to a .200/.241/.240 line. With another offseason to refine his arsenal and another potential weapon to make hitters' knees knock, there's every reason to believe Herrera could be even more of a beast this year.
2015 Herrera ended the season as the lead consonant in Kansas City's now-legendary HDH bullpen, but entered it as just another bullpen arm. Well, okay, just another bullpen arm with a triple-digit fastball and devastating changeup. The difference for him last year was the gopher ball, or lack thereof. His strikeout rate surprisingly clocked in right at league average, but most of the missing third strikes were replaced by lazy two-hoppers, so never fear. Ned Yost's admirable decision to use Herrera in multi-inning playoff appearances speaks to his value, and as long as he keeps his fastball down, he'll remain an elite late-inning beast.
2014 Armed with a fastball with an average velocity of 98 mph, Herrera throws pure heat. Mix in a filthy change and itís a two-pitch combo that is as lethal as you can find in the game. Yet his arsenal was as effective as wet gunpowder through his first 19 appearances. In those 20 innings, he surrendered eight home runs, including three in an inning against the Braves in mid-April, earning him a trip to Triple-A. He was up and down one more time before returning for good to the Royals' bullpen in July. Over his final 30 innings, he allowed just a single home run and was one of the clubís more effective relievers down the stretch.
2013 After rocketing through four levels in 2011, Herrera kept the moving trucks at bay in í12, spending the entire year with the big club. Itís as if he enters the game with a flamethrower attached to his arm: His average fastball velocity of 97.4 mph was the highest in the AL and second only to Aroldis Chapman in MLB. He uses the fastball to jump ahead and then finishes off hitters with a filthy changeup. When foes actually put the ball in play, itís frequently on the ground. The Royals bullpen is flush with quality arms, and Herrera may be at the head of the class. Closer material to be sure.
2012 Herreraís checklist for the 2011 season: Breeze through High-A? Done. Dominate Double-A? Yep. Crush the spirits of Triple-A hitters? Complete. Earn a spot on the 40-man roster and a September call-up to Kansas City? Mission accomplished. After missing almost the entire 2009 season and most of 2010 with elbow issues, Herrera made a definite splash in 2011. Moved to the bullpen in an effort to protect his elbow, he fires a fastball in the upper 90s (touching triple digits at times), keeps the ball down, and flat misses bats. After moving so rapidly through the system, itís conceivable he could open the year in Triple-A for a dash more seasoning, but after his big year, the Royals are now counting on him to be a big part of the future bullpen in Kansas City.

BP Chats

DateQuestionAnswer
2014-11-12 13:00:00 (link to chat)Are the Dodgers and Cubs implicitly following Lewie Pollis' advice to spend indiscriminately on management?
(ssimon from Pelham, N.Y.)
Implicitly? I guess. Explicitly? I... guess. I'm not totally sure I believe it's the right way to do it, to be honest. I think there are so many smart people out there right now that front office guys might be more like relievers than anything. Fairly unpredictable (even the seemingly great ones), fairly replaceable, fairly short window of genius. The Dodgers have signed a ton of big front office guys this year. It seems like a great idea. But so did spending $30 million on a bullpen last offseason. Turned out the right answer was "Wade Davis and Kelvin Herrera," and nobody knew it. (Sam Miller)
2014-10-17 12:00:00 (link to chat)Is Ned Yost just inconsistent or is he getting better?
(William from Spokane)
He's getting better. A crucial thing happened in September. The Aaron Crow Game (the cousin of The Jonny Gomes Game) showed the limits of Yost's rigid bullpen management. After that game, pitching coach Dave Eiland implored him to be more aggressive in using Kelvin Herrera and Wade Davis.

One point to Yost's credit: He listened. The next night, Herrera pitched in the sixth. Davis pitched in the seventh.

Another point to Yost's credit: He did not waver. Because the Royals lost that next night, and Yost could have easily backslid into the routine. He didn't.

During the ALCS, multiple Orioles officials lamented to me their frustration that Yost had optimized his bullpen deployment. It was almost unfair, they said. And this was when the team wasn't even using Danny Duffy, who was their best pitcher for much of the summer.

So, in short, Yost has gotten better. He still does goofy things, like letting his No. 3 hitter bunt in the first inning. But they've found a horseshoe. At this point, it's Ned's world, and we're all just living in it. Hope you are all enjoying the #Yostseason. (Andy McCullough)
2014-05-21 13:00:00 (link to chat)Scoresheet league here .Don't have a real closer.Alternating between David Carpenter,Jake McGee and Kelvin Herrera at this point.Based solely on E.R.A,who would you entrench as your closer the rest of way ?
(Spirou from Montreal)
Herrera for me (Paul Sporer)
2014-03-14 09:00:00 (link to chat)I'm in a league that has holds as a category. Who are 3 guys I can target?
(DServi4 from Maryland)
I never really recommend targeting pitchers specifically for holds. With non-closers, I'm an advocate for going for skills, not roles. If you are going to target holds, though, I would probably go with Brian Wilson, David Carpenter, and Kelvin Herrera. I like the idea of getting pitchers behind strong closers, since you reduce your risk of losing holds with a solid option in the stopper role. (Mike Gianella)
2013-09-26 13:00:00 (link to chat)Looking for saves in 2014, how many of these guys are capable/likely to grab 20+ saves next season: Trevor Rosenthal, David Robertson, Cody Allen, Jake McGee, Brian Wilson, Luke Gregerson, Pedro Strop, Drew Storen, Ryan Cook, Carlos Martinez, Vic Black, Joakim Soria, Neftali Feliz, Steve Delebar, Kelvin Herrera, Carter Capps, and/or AJ Ramos?
(J-Qwellin from Deplorable Future Leaders of America Club)
J-QWELLIN!!!! Interestingly enough, I'm working on such a piece re: 2014 closers. From your group, I'd go Rosy & D-Rob, but honestly any of them have the capability. I know that's a little copout-y, but that's the nature of the beast with relievers. (Paul Sporer)
2013-02-27 20:00:00 (link to chat)Romo & Holland are amongst my keepers this season - do both keep their closer jobs all year?
(Mike from Chi-town)
I'd say yes to Sergio Romo in all likelihood... keeping in mind that the Giants aren't afraid to switch roles at the earliest sign of trouble. I think Greg Holland will be OK, but Kelvin Herrera is extremely talented. If you're a believer in the skills versus roles thing, Herrera's a guy you'll want to grab in deeper formats. (Mike Gianella)
2013-02-15 12:00:00 (link to chat)Are the chances good that Carter Capps and Kelvin Herrera can unseat Tom Wilhemsen and Greg Holland is the (primary) 9th inning option?
(Mateo from Reno)
I'd say more for injury than skills as I like both of those incumbents. (Jason Collette)
2012-12-18 13:00:00 (link to chat)Seattle and KC don't have a closer who has his gig locked down. I'm betting on Carter Capps in Seattle and Kelvin Herrera in Kansas City (unless Ventura is moved to the bullpen down the road). Smart money, or should I invest in someone else?
(Jonah from Brooklyn)
What's wrong with incumbents Wilhelmsen and Holland? You can speculate on those others on the cheap, but I'd still bet on the 2012 guys. (Paul Sporer)
2012-12-28 13:00:00 (link to chat)When will Kelvin Herrera supplant Holland for closing duties in KC?
(John from Kansas City)
Hi John. I'm guessing as soon as the Royals find a taker for Holland? It shouldn't be hard; he's a good pitcher. (Geoff Young)
2012-12-28 13:00:00 (link to chat)Kelvin Herrera in KC, Arodys Vizcaino in North Chicago, and Carter Capps in Seattle. Who has the best chance to lead their team in saves in 2013?* In 2014? (*I know Vizcaino is coming back from TJS).
(Kevin from Des Moines)
Thanks for the question, Kevin. Trying to guess save opportunities is a fool's errand, but I'll go with Herrera on the basis that he has the most big-league experience. (Geoff Young)
