Matt Martin has coached Nick Castellanos for seven years, helping to build the right-handed swing that produced the sixth-most extra-base hits in the majors from 2016 through last season. He often hears from envious hitters who point to Castellanos and say, “I wish my swing could look like that.”
Who better, then, to explain why the Phillies’ $100 million slugger has struggled so badly in his first season with the team — and how he may finally be able to get on track?
“The swing itself right now, it looks good. It’s getting there,” Martin said Wednesday night by phone. “He just hasn’t been right. And he’s made it worse with all the right intentions.”
