Yandy Diaz
Yandy Diaz has 7 home runs in just 109 plate appearances for the Rays this season. He had just one homer in 299 MLB plate appearances with the Indians in 2017-2018. When the Rays traded for Diaz many thought they would teach him to lift the ball and that would be an easy explanation… if it was true.
Diaz has a 2.9-degree launch angle this season, while he had a 4.4 mark in 2018.
He does have a career-high 30.1 percent flyball rate, with a 56.2 percent groundball rate. So what explains the power gains? He has a 31.8 percent HR/FB rate. That means that he hits the ball in the air about a third of his at-bats, and so far a third of those fly balls have left the yard. The problem? That is a very high number and tough to sustain.
The only hitter with a HR/FB over 30 percent in 2018 was Christian Yelich (35 percent). Going back to 2010, there have been just six hitters to finish a season with a HR/FB rate over 30 percent. Can Diaz join this group? Yes, but the chances are slim.
While the power has been a huge plus to Diaz’ game, it is still tough to trust the power is for real until we see him begin to lift the ball more. I am not saying to sell Diaz, as I am actually quite high on him, but the power pace seems unsustainable.
