SURPRISE, Ariz. -- A blister problem will keep Royals reliever Doug Waechter off the mound for a few days.

The right-hander developed the problem following his Cactus League debut on Feb. 28, when he threw a hitless inning against the San Diego Padres.

"We'll see how he progresses in the next couple of days," Royals manager Trey Hillman said Wednesday afternoon. "We're taping him up so he can get his other work in.

"His fingernail is involved with it. He won't be able to pitch for a couple of days, but he is able to do the other work."

Drafted in the third round of the 1999 First-Year Player Draft by Tampa Bay, Waechter signed a one-year deal with the Royals in December as a Minor League free agent. In parts of five seasons with the Rays, he went 18-27 with a 4.41 ERA.

Converted to a full-time reliever last season, Waechter produced the best season of his career for the Florid Marlins, going 4-2 with a 3.69 ERA in 48 appearances.
