Chicago manager Ozzie Guillen said based on recent team success and the ability to give players more rest, Viciedo's Major League debut will be pushed back.
"This matchup [against right-hander J.D. Martin] is pretty good because I have a chance to play [Omar] Vizquel today and give him two days off," Guillen said before Saturday's contest. "I'm trying to give [Vizquel] the most at-bats we can. The way we have been playing, I wanted to go with the same lineup."
Playing the rookie on Sunday against the Nationals could be more to his favor. The right-handed-hitting Viciedo would take on Washington left-hander John Lannan, rather than Martin.
With Charlotte, Viciedo hit .364 against left-handers compared to .268 against right-handers. He was hitting .290 overall with 14 home runs and 34 RBIs.
