Miller's career-high 20 homers in 2016 have mostly been over 400 feet, his most extensive power display at any level in his career, Sam Blum of MLB.com reports. "He's got really good hands. He's really strong," Rays hitting coach Derek Shelton said. "What he does with his contact point and where he gets the ball is what enables him to hit the ball hard and get the ball elevated."
Miller has particularly been on a tear over the last two months, during which he's blasted 15 of his 20 round-trippers. The distance on those homers has notably shot up when compared that of the 11 he managed for the Mariners in 2015, which averaged 391 feet with an average exit velocity of 102.8 mph according to Statcast. Those figures have seen a boost to 415 feet and 105.8 mph in 2016, with the former number placing him fifth in the majors behind the likes of sluggers Carlos Gonzalez, Giancarlo Stanton, Trevor Story and Nelson Cruz. Perhaps most impressive is the fact that the has managed to nearly double his HR/FB rate from the 10.3 percent he managed in 2015, currently knocking 20 percent of the pitches he puts in the air out of the park. Although the overall power numbers are certainly a revelation, the Rays were aware they were getting a player with the ability to make hard contact consistently when they acquired Miller, a trait that is keeping him in the lineup despite the recent displacement from his natural shortstop position due to the imminent arrival of newly acquired Matt Duffy. "We did have a lot of confidence and were very optimistic about his bat and his overall play," Tampa Bay manager Kevin Cash said. "And we've seen that. The actual home run numbers, I think you could say are a little bit of a surprise. He hadn't done that before. I don't know if he's ever hit 20 home runs anywhere."
