His success on the mound has come largely due to an impressive fastball that Arteaga describes as having ‘an extra gear.’
“He has great arm strength,” Arteaga said. “He might not be the hardest thrower on the staff because we have a lot of hard throwers, but his fastball has a different gear to it where it kind of accelerates as it gets to the plate. His secondary stuff has some work to do, but his fastball has got something special about it that you really can’t teach where it kind of has that second gear to it.”
Walters likes to study one of the most electrifying young arms in professional baseball in Los Angeles Dodgers’ standout Walker Buehler. Miami’s new right-hander sees some similarities in their fastballs and has tried to incorporate some of Buehler’s pitching style into his approach on the mound
“Watching Buehler, I can see how hitters react to him and how he pitches in certain situations,” Walters said. “He is a more fastball-type guy and I do tend to throw a lot more fastballs so I just try to base my game off what he does because he’s very successful. I want to be in that situation one day, so I watch him and I look at his pitch selection. I think Buehler is more of my mindset, so I think modeling myself off him gives me better insight.”
In addition to fine-tuning his fastball, Walters spent much of the fall working on his secondary pitches and improving his mechanics.
“It’s not really clicking yet, but we’re trying out a splitter now,” Walters said. “J.D. thinks it’s going to be the best thing for me and it started working a little bit more towards the end of the fall. But he has mainly been teaching me to work more with my legs. I like that he sees that he can get more out of me. We will continue to work on mechanics and different pitches to help me succeed.”
Arteaga has enjoyed working with Walters and believes he has the right approach to getting better as a player.
“He’s very soft-spoken and very quiet, but a great listener and a very, very hard worker,” Arteaga said. “In our conditioning, he’s out in the front end winning every drill we’re doing. Andrew works very hard and he’s more of a listener than a speaker, but definitely a guy that’s very fun to coach.”
Walters has built a good bond with Arteaga and appreciates his hands-on approach to coaching his pitchers.
“J.D. is always working with us and I love that I have the opportunity to learn from him,” Walters said. “J.D. is always in there working with us and you never have to worry about anything. You’re always getting the time you need with him and he’s making you a better player in all aspects of pitching. I like that and it’s definitely helped me a lot.”
