WASHINGTON -- Third baseman Dayan Viciedo, called up to the White Sox on Friday from Triple-A Charlotte, is not expected to play Saturday against the Nationals.
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.
Konerko, Rios given day off
WASHINGTON -- Paul Konerko and Alex Rios were given the day off for Saturday's matchup against the Nationals.
"Alex seems kind of tired right now, so we'll give him a day off today and hopefully they'll recover the next day," White Sox manager Ozzie Guillen said. "Monday, we have the day off and then hopefully we'll go back to what it was."
Konerko entered Saturday third in the American League in home runs with 17 and is hitting .386 in his last 12 games.
Rios has also been playing well as of late. He has hit safely in 21 of his past 26 games and has a .331 batting average in his last 47 games. In Friday's 2-1 win against the Nationals, Rios had both RBIs.
Guillen trusts Peavy's assessment
WASHINGTON -- While White Sox manager Ozzie Guillen does not have the long-term relationship with right-hander Jake Peavy that he has with other veteran pitchers, the level of trust is the same.
And when Peavy, who has felt soreness in his right shoulder and had his recent start pushed back two days, said he felt fine heading into Saturday's matchup with the Nationals, Guillen believed him.
"I know those guys very well," Guillen said of veterans Mark Buehrle and Freddy Garcia. "I know Peavy good, but I don't think I know him good enough. The one thing I respect, when you say I have a tired arm or shoulder, it's my job to take care of that. But when you are on the mound, you're pitching. No excuses.
"We've talked to him a lot about it. We spent hours and hours talking about this issue. I think mentally he's pretty good. I don't see why he would have any problem today."
Peavy was traded to the White Sox from the Padres last August for four pitching prospects. He entered Saturday's start 5-5 with a 5.62 ERA.
Nats' Storen a fan of 'Big Hurt'
WASHINGTON -- Growing up near Indianapolis, Ind., Nationals rookie reliever Drew Storen didn't have a professional baseball team close enough to call his own. Instead, he chose particular players to follow and root for.
One of his idols was former White Sox designated hitter Frank Thomas, currently working as a White Sox pregame and postgame analyst for Comcast SportsNet in Chicago.
"Growing up close to Chicago, my dad and I would go all the time to White Sox games," Storen said. "I used to be a huge Frank Thomas fan. I made my parents call me 'Big Frank.'"
Storen said Thomas was one of his favorite players because "he was huge and hit big home runs."
The White Sox were never his top team, but based on his affection for Thomas, he was excited to face them this week.
"Being on the other side, after going to so many White Sox games, is cool," Storen said.
