The improvements made by American League Central rivals elicited an array of responses from a White Sox team that didn't make a blockbuster move after an 85-win season in 2012.

"The division is going to be tough," general manager Rick Hahn said Tuesday while praising Indians management for its creativity. "Obviously Cleveland has improved over the 68-win team they were last year. And Kansas City has improved over the 72-win team they were last year as well."

Pitcher Jake Peavy said the reinforcements by other teams should serve as motivation.

"Those moves are making those teams better," Peavy said. "And if we're not motivated and doing the things we're supposed to do and capable of doing, we're not going to beat those teams."

Left-hander John Danks, however, wasn't consumed by other teams' moves.

"We try not to worry about what everyone else is doing," Danks said. "We know if we play up to our capabilities, it all should take care of itself."

Hahn said he has remained in contact with several clubs about trade possibilities.

Crack in closer's door: Hahn endorsed Addison Reed as the closer but stressed that manager Robin Ventura has plenty of options, such as left-hander Donnie Veal or Matt Lindstrom, if a more favorable matchup arises or Reed needs a rest.

"A lot of times it will be Addison in the ninth, and sometimes perhaps it might not be," Hahn said.

Reed had a 5.17 ERA after the All-Star break, when Brett Myers and Matt Thornton were used more frequently to start the ninth in save situations.
