ROUND ROCK, Texas -- If Mike Olt comes up to the big leagues and helps the Rangers later this season, Manny Ramirez might deserve a small portion of the credit.

Ramirez, with Triple-A Round Rock attempting a comeback of his own, noticed a flaw in Olt's swing in the past few days. Olt, the Rangers' top hitting prospect in the minors, made an adjustment and had a 2-for-3 night with two of the hardest-hit balls in Sunday night's 4-0 victory over Omaha.

Olt was in a 1-for-22 slump before Sunday night's one-game turnaround, that after being on a home run tear since returning from the disabled list with vision issues.

Ramirez has a reputation for being religious about studying video, so Olt asked him to watch some clips of his swing.

"He saw that I was late and dropping my hands," said Olt, who made his debut with the Rangers last season, playing in 16 games. "We went to the cages and I worked with him."

Olt cranked a single on a 1-1 fastball in the third and had a double on a first-pitch fastball in the seventh inning. Round Rock hitting coach Scott Coolbaugh wants his players to stay aggressive on fastballs.

Coolbaugh welcomes Ramirez's knowledge and willingness to help his young teammates. Ramirez has a pedigree for being one of the best hitters of his generation, with, among other things, 555 career home runs.

"It's huge coming from a teammate," Coolbaugh said. "Mike is trying to get where Manny has been and has had a lot of success. It shows a lot of leadership skills."
