Case Study: Why Matt Harvey lost his fastball velocity in 2018 – and eventually found it again in Cincinnati
It’s the evening of November 1, 2015 and the New York Mets are fighting for their lives in a do or die Game 5 against the Kansas City Royals in the World Series. On the brink of elimination, Terry Collins turned to Matt Harvey – baseball’s feel good story winning NL Comeback Player of the Year after missing 2014 to Tommy John. Harvey was not just good on that November evening – he was masterful. In peak “Dark Knight” form, Harvey held the dangerous Royals offense to zero runs through eight innings running his electric heater up to 98 mph. When Terry Collins thought it was a good idea to go to the bullpen after eight, Harvey didn’t ask Collins to go back out; he told him he wasn’t finished. Up 2-0 with three outs to go, Harvey sprinted out to the mound to the roar of the Citi Field crowd determined to finish off his masterpiece. It was the picture perfect story for the 2015 NL Comeback player of the Year, but it didn’t quite finish the way Mets fans had hoped. After a leadoff walk and a Eric Hosmer double, Matt Harvey was forced to watch the rest of his lead slip away from the Mets dugout. The Royals would go on to put up a 5 spot in the 12th to finish off the Mets in five games to put an abrupt ending to their magical pennant run. It’s tough to predict what could have happened if Collins had dismissed Harvey and sent out his closer Jeurys Familia for the ninth, but there is one thing we can know for sure – Harvey’s heroics through eight were his last shining moment as a New York Met.
If we fast forward the clocks to April 25, 2018, Matt Harvey no longer owns a spot in the Mets starting rotation. The former 2013 All-Star was demoted to the bullpen after owning an ERA north of 6.00 and suffering from the lowest fastball velocity of his career (93 mph). Less than three years ago, Harvey was pounding his chest to a roaring crowd and overruling his manager’s decision to go out for the ninth inning of an elimination game in the World Series. To say this was an unexpected turn of events would be an understatement.
Now here’s where the story gets interesting. Just two weeks after Harvey’s demotion to the bullpen, New York decided to ship him off to Cincinnati for catcher Devin Mesoraco. Over the next five months, Harvey would start 24 games for the Reds winning seven and dropping his ERA down to 4.50 (not great, but it’s not the whole story). In his short stint with the Mets, Harvey’s fastball averaged out at a career low 93.3 mph. After changing uniforms, his fastball jumped back up to 94.8 – his fastest since 2015. Along with this, Harvey’s K/9 improved from 6.7 to 7.8, he dropped his BB/9 from 3.0 to 2.0, he doubled his K/BB from 2.22 to 3.96, his WHIP dropped from 1.556 to 1.250, and his H/9 improved from 11.0 to 9.3. The video below is from September of 2018 – four months after struggling to touch 94 on the gun. This pitch was 97.
If we look at Harvey’s 91 mph fastball from April and compare him to September of the same year, we notice two completely different moves that could explain why he started to have some success after his trade to Cincinnati. For one, Harvey’s arm slot lowered in Cincinnati. When he was in New York, his arm was climbing above the plane of rotation around his shoulders. This position creates an inefficient arm action and could have played a pretty significant role in his diminished velocity, health, and durability.
If we slow it down, this is what we looks like synced up to release in both frames.
If you were to draw a straight line out from the shoulders perpendicular to the trunk at ball release, the throwing arm should be on that line (i.e. the plane of rotation). When Harvey was struggling for velocity early on in the year, his arm was climbing above the plane of rotation into an inefficient position. When he rediscovered his velocity in Cincinnati, his arm slot started to lower into a position much more favorable in relationship to his trunk.
Now let’s break down another glaring difference: Harvey stops significantly better in Cincinnati. In the clip with New York, you’ll notice how Harvey’s arm yanks down after release and bangs against his torso. When guys climb above the plane of rotation into release, they have to come back down after ball release. This climbing and sudden yanking down creates a poor deceleration pattern that can impact velocity, command, and arm health. On the right, you notice a completely different move. Instead of yanking his arm through, Harvey stops his arm much better and actually “pimps the finish” (better known as an arm recoil).
This move is not forced like the one from the left. Instead, it is a muscle spindle reflex created to dissipate a large amount of tension in the system after ball release. It’s something you see from some of the hardest throwers on the planet; and it’s not by coincidence. It’s not just an indication that someone is trying to throw smoke – it’s indicator of awesome decelerator strength. When we stop better, we transfer force better, throw harder, and command the ball with more precision (see 0:20 in video below).
Matt Harvey may not ever completely return to Dark Knight form, but his 2018 resurgence is a great example of how moves can change, evolve, and either positively impact performance or deteriorate it. The goal then becomes to catch when things go wrong and get athletes back on track as quickly as possible. Matt Harvey won seven games for the Cincinnati Reds in 2018. While those seven games might not have meant much to the Mets or Reds in 2018, they would have meant a hell of a lot to four other teams fighting for division titles that year that had to settle things in game 163. Good player development takes guys like Harvey who get off track, helps them create the adjustments they need, and puts them in situations where they can help their team win championships. When you boil a 162 game season down, the differences between good and bad players and winning and losing ball clubs are much smaller than you’d think. Failure to take advantage of these critical moments of time can ruin careers, cut seasons short, and prevent you from making the most with what you have.
Harvey wasn’t the same guy in 2018 that he was in 2013, but he definitely still had something left in him. When players have something left in the tank that they can’t access on their own, it’s our responsibility as coaches to help bring it out of them. Harvey will always be an unfortunate example of what could have been, but he’s also a great example of how a change of scenery and some better moves can completely change your season.
