CHICAGO -- The Royals promoted shortstop Christian Colon, the club's first-round pick (No. 4 overall) in the 2010 First-Year Player Draft, to Triple-A Omaha on Tuesday.

Colon, 23, produced a .289/.364/.392 line with nine doubles and five home runs in 73 games with Double-A Northwest Arkansas. He also swiped 12 bases and drew 31 walks compared to 27 strikeouts.

Colon, a Cayey, Puerto Rico, native, was drafted out of Cal State Fullerton. He's a career .273 hitter in 267 Minor League games and should get playing time at short after the Royals on Monday selected the contract of Tony Abreu, who had been the Storm Chasers' starting shortstop.

When asked if Colon could be a player the Royals look at as a potential September callup, Royals manager Ned Yost responded by saying it's "way too early to think about."

Escobar, Cain get a chance to rest

CHICAGO -- As expected, Alcides Escobar received the day off Tuesday against the White Sox, only the third time this season the shortstop wasn't in Kansas City's starting lineup.

Center fielder Lorenzo Cain also got the night off, just his fourth time out of the starting lineup after missing 78 games earlier this season with a left groin strain and torn left hip flexor.

"Esky's had one day off all year, really," said Royals manager Ned Yost, who added this is the time of the year he starts giving players more days off. "He came and he had another day off and played half the game, so he's had one day off all year. Cain's played a bunch of games in a row since he's come back."

Utility infielder Tony Abreu -- who started his first Major League game since Oct. 3, 2010, on Monday at third base -- started Tuesday in place of Escobar. Jarrod Dyson was in center instead of Cain.

Dyson, who has seven-game hitting streak, during which he's batting .480 (12-for-25) with five stolen bases, has received extended playing time in the past couple of weeks during Jeff Francoeur's struggles. Francoeur was back in right field Tuesday, one day after going 2-for-4 with a home run.

"Our whole goal was to get [Francoeur] swinging the bat again and he's been swinging the bat fine," Yost said.

Third baseman Mike Moustakas was back in Tuesday's starting lineup after missing the previous two games with a bone bruise on his right knee.
