Forget the late-season slump and the struggles against right-handed pitching, the Chicago White Sox remain supremely confident that Dayan Viciedo will emerge as a powerful force in the American League.

The latest to pick up the cause for the right-handed power hitter was hitting coach Jeff Manto, whose handiwork will be evident from the moment spring training begins.

“We’re going to ask him to add a little leg kick for a timing mechanism,” Manto said Thursday about the slugger that won’t even turn 24 until next month. “That’s not going to be a big deal.”

Actually, it could be a very big deal if Viciedo uses the leg kick to trigger the kind of explosive season the White Sox are counting on seeing at regular intervals.

The curious case of Viciedo is that despite 25 home runs, 78 RBIs and a .444 slugging percentage in 2012, the White Sox still see so much untapped potential.

“He's going to get better once he gets the timing down,” Manto said. “That's what's scary about this guy – he didn't do a lot of things right and he had those numbers. Once he calms himself down and understands what the pitchers are doing to him, he's going to be a big-time impact player. I really believe that.”

General manager Rick Hahn addressed a Viciedo inquiry at SoxFest by saying the reason the White Sox didn’t show interest in a left-handed hitting outfielder like Jason Kubel is because a move like that would make Viciedo a platoon player. The White Sox aren’t about to cut into his playing time, even if he only batted .225 with a .380 slugging percentage against right-handers.

“The numbers he put up (in 2012), they're legit,” Manto said. “It's a shame he got a little cold at the end of the season, but these are numbers he can sit on.”
