Dayan Viciedo hadn't hit a home run since May 15, but he hadn't struck out in his last 12 at-bats entering play Saturday night.

Hitting coach Jeff Manto prefers that his streaky slugger continue to concentrate on hitting the ball to all fields rather than trying to pull every pitch and leaving himself more susceptible to strikeouts.

"Obviously, he has a lot of power all over the field," Manto said of Viciedo, who hit 25 home runs last year and drove in 78 runs. "The power mainly starts in right-center field. When he's thinking out there, he can do a lot of damage to left field, but he has to try to convince himself to stay on the ball and stay to right-center."

Viciedo is one of several Sox who haven't come close to matching their power production of 2012. Although Viciedo missed three weeks because of a left oblique strain, he has hit only four home runs in 155 at-bats. But Manto hasn't given up hope that the power will return at some point.

"I truly believe he's a 25 (home run)-75 (RBIs) guy and will hit for .250-.260, maybe higher," Manto said. "That's the kind of ability he has. But right now, mentally, he's trying to play catch-up. It's just a matter of taking time and let it take its course, rather than trying to hit the five-run home run. Take the double, take the single, and those things will come.''

Manto said the implementation of a leg kick in spring training was designed to help Viciedo with his timing and prevent the length of hitting droughts that he has experienced. Viciedo was batting .118 during the first two weeks of the season before raising his batting average to .303 on May 18, only to go through an 0-for-13 slump.
