This turnaround has been amazing for Dozier, but it has not been entirely unexpected. In the spring, Dozier showcased new mechanics
that should have helped create a more firm platform out on his front foot as well allow him to open up his hip to better. Once the season started however his production remained static.
Hitting coach Tom Brunansky is familiar with Dozier after working with him for several seasons in the minor leagues and tinkering with his swing. Brunansky admitted earlier in the season that his approach is about getting hitters to have a feel for the swing rather than replicate something visually. Dozierís problem, Brunansky diagnosed, was his timing.
So, as 1500ESPN.comís Brandon Warne found out from Dozier and Brunansky recently, the second baseman began plotting on ways to improve his timing at the end of May:
Dozier said he and Brunansky spent that night and most of the next day studying to get a feel where he was misfiring.
They counted 'clicks' before the pitcher releases the ball to the time of contact. According to Dozier, the process starts once a hitter's foot hits the ground.
"Once your foot is down, you start counting the clicks in your swing," Dozier said. "Good hitters who have their foot down can see the ball -- for instance, Mauer has eight or nine clicks -- and I was only having like three."
Although Dozier speaks towards the point of the foot strike, his timing was thrown off earlier than that Ė when he first would begin his swing at the foot lift:
While facing this low-90s fastballs from left-handed pitchers, we see that Dozierís front foot lift begins much later in May (LEFT) than it in August (RIGHT). In the first instance, Dozier received a fastball middle-up and instead of pulling the ball, his timing is behind and he fights it off towards the right-center field gap.
The next images are of his foot strike Ė the point where his front foot lands in his strike. Take notice where each pitch is in the examples. In May, the pitch is already on him. In August, the pitch has just been delivered. The latter gives him ample opportunity to read the ball and react instead of fighting off pitches.
The same trend can be found for Dozier versus right-handed pitchers as well. In this example of earlier season versus late season, we see the same pattern Ė Dozier is beginning his swing much later.
Why is Dozierís timing a huge issue? For starters, it means a better command of the strike zone as it gives him a longer (relative) look at each pitch. No longer does Dozier have troubles with in zone fastballs as his bat does not drag through the zone late. Now heís driving balls all over the zone, particularly on the inner-half.
Notice in this heat map below that prior the end of May (LEFT), Dozier was struggling to do anything with pitches inside the strike zone. After May (RIGHT) Dozier was doing damage on those same pitches and was turning on those thrown inside (a location he struggled to do anything with prior to June). Since his and Brunanskyís work, that area of the strike zone has been one in which he has been most productive.
While Dozierís heat map shows how well heís done at the plate, but his spray chart shows how well heís succeeding after the ball has been put into play. Advertised as a pull-ball hitter in the minor leagues, Dozier has not fulfilled that potential at the big league level. It is easy to conclude that part of what was impeding him has been his timing issue. As you can see in his spray chart below, prior to May (LEFT) Dozier did not hit much down the line. After making changes to his timing mechanism, Dozierís ability to pull the ball greatly increased. Here you see that the bulk of his hits since June 1 came down the left field line:
Clearly, a vast majority of his hits have gone to the left side as he exhibited a significant amount of power to boot.
Combined with his stellar defense, Dozierís offensive turnaround as made him one of the teamís top contributors at a position that has become increasingly more offense-oriented in recent years. It may seem like a completely subtle change, but timing Ė even fractions or fractions or seconds Ė can be vital to a playerís swing. Credit both Dozier as well as Brunansky for this surge.
