Royals 4, White Sox 3: Alex Gordon and Salvador Perez delivered back-to-back doubles in the bottom of the eighth inning as host Kansas City defeated Chicago for the second straight day.

Gordon smacked a two-out double into the right-center field gap off Scott Downs (0-1) and Perez followed with a sharply hit ball down the third-base line off Maikel Cleto to score Gordon. Greg Holland worked around a leadoff walk in the ninth for his second save.

Billy Butler drove in two runs and Mike Moustakas had the other RBI for the Royals. Chicago tied the contest at 3 in the eighth on Conor Gillaspie’s RBI single and Paul Konerko’s sacrifice fly against Wade Davis (1-1).

Butler had a run-scoring single and Moustakas drew a bases-loaded walk in the fourth off Danks, and Butler hit a sacrifice fly in the fifth for the third run. Adam Eaton’s infield out in the top of the fifth plated a run for the White Sox, who have lost three straight games.
