CLEVELAND — You don't need a medical degree to appreciate Pablo López's changeup. But it might help you understand why it's so good.
"I went through a whole thing last offseason learning about pronation and supination and how certain muscles help you get different movement on the ball," the Twins righthander said. "I don't know if it made the pitch better, but I hope so."
In the judgment of managers, coaches and scouting staffs around the majors, it did. Baseball America magazine's annual best-tools survey of each team's experts was released this week, and López's version is rated the second-best changeup in the American League, behind only Tampa Bay Rays lefthander Shane McClanahan.
"That's really nice to hear," López said. "Last year, it was the only reliable off-speed [pitch] I had, so I worked to make it better. Guys tell me they think it's a fastball until it's not."
Two other Twins were ranked in the top three in the various categories in the survey, with Jhoan Duran's fastball judged the best in the league, and his curveball third-best, behind Framber Valdez of Houston and Tyler Glasnow of Tampa Bay. In addition, Carlos Correa's throwing arm was ranked second-best in the league to Toronto Blue Jays third baseman Matt Chapman, the fifth consecutive season Correa has finished in the top three.
"I'm not surprised by any of those," Twins manager Rocco Baldelli said. "It's good to see Jhoan be recognized for more than speed. When he's throwing that curveball at his best, it's not a pitch than can be hit. It's a pitch that's going to get swung at and missed by a foot more often than it's hit hard. When he throws it right, guys miss it by a lot."
As for Duran's fastball, Baldelli noted that "I've never seen a guy throw 104 mph before. But the thing is, I don't care how [fast] a pitch is, if it's right down the middle, it's a hittable pitch."
The secret, he said, is being able to place the pitch exactly where you want it, and mixing it up with other pitches.
