Tuesday's win came behind three solo home runs from Alejandro De Aza, Beckham and Alex Rios and great pitching from Gavin Floyd. The right-hander needed just 78 pitches to cover seven innings and according to MLB.com Gameday, he was hitting 94 mph with the fastball as late as four pitches from his finish.
Five straight wins, including four straight on this nine-game road trip interrupted by Monday's makeup game victory over the Tigers, dropped the White Sox magic number to 13 to eliminate Detroit and held their division lead at three games. Chris Sale goes for win No. 18 in his first year as a starter, while White Sox crusher Bruce Chen takes the mound for the Royals on Wednesday.
"This whole season has been something that I've never experienced," Rios told reporters. "Every day when you come to the field it means something. It means that you have to come and do something good to try to win games. It's been a [great] season."

To calculate a team's magic number, take the number of games it has remaining and add one. Then subtract the difference in the number of losses between that team and its closest pursuer.
A tiebreaker game will be played to determine a division winner, even if the tied clubs are assured of participating in the postseason. If a division championship tiebreaker is necessary, the head-to-head record between the clubs will determine home-field advantage. If the head-to-head record is tied, then the division record will be the next tiebreaker.
If two clubs are tied for the two Wild Card berths, home-field advantage will be determined by the head-to-head record between the clubs. If the head-to-head record is tied, then the division record will be the next tiebreaker.
