Marlins left-hander Adam Conley will be working on maintaining his strength during the season.

JUPITER — Adam Conley hasn’t taken an aspirin since 2012. He drinks water out of an alkaline ionizer to decrease its acidity. He has embraced chiropractic practices. He cooks at home almost always with farmto-table, non-genetically modified ingredients — and when he does go out to eat, it’s often at Chipotle, which has a full non-GMO menu.

Why? Because he wants to emerge as the best pitcher in a Miami Marlins rotation that lacks a clearcut leader.

“For me to perform at my highest level, these are things I’m convinced are the decisions and the choices that are going to help me be the best I can be,” Conley said. “There’s a lot that goes into it.”

It’s all a part of the lefty’s holistic approach to taking care of his body, his attempt at being as healthy as possible so he can be as successful on the mound as possible.

It wasn’t always this way. As a young minor leaguer, Conley used to go into the offseason simply looking to add weight in the form of muscle — the bigger the better. He would show up to spring training with his 6-foot-3 frame nearing 220 pounds. But by the end of camp, he’d be back down near 205. By the end of the season, 197.

It wasn’t working, so Conley, now 26, altered his strategy. He accepted his body for what it is — long and skinny — and focused on his posture, the integrity of his joints, and his range of motion more than straight muscle.

“I was born a tall skinny guy,” Conley said. “Rather than try to change that, I’m going to use what I have to the best of my ability and just be as strong and as durable as possible.”

Strength, manager Don Mattingly said, is one of two areas the Marlins want Conley to focus on so he can take the next step in his big league development. The other is a more consistent delivery. Together, they should help Conley maintain his velocity, an issue for him last year when his fastball nearly touched 97 mph in his first start of the year but averaged not quite 91 mph before the All-Star break.

If Conley can maintain strength and keep his body moving in the same direction every time he throws, the rest will come.

“Keep the strength all year,” pitching coach Juan Nieves said. “Regardless of what the result is in the game, keeping strength is important. Because with that comes his power fastball, power slider, ability to change speeds.”

This year is a big one for Conley, who in 2016 experienced his first full major league season — albeit while sitting out for six weeks with a broken hand.

He finished with a 3.85 ERA and 8.4 strikeouts per nine innings (a rotation-best outside of Jose Fernandez), plus a 1.40 WHIP and 4.2 walks per nine.

There were also flashes of something greater — 7 2⁄3 hitless innings against Milwaukee in April, eight scoreless against Atlanta in June, nine strikeouts in six shutout innings on two occasions.

“He showed some signs of brilliancy last year,” Nieves said. “We all saw some games [last year] where you go, ‘Oh my god, this guy is special.’ ”
