So who was the best pitcher in the American League during May? None other than Lucas Giolito, who this season has broken through and lived up to his vast potential. He is 7-0 with a 1.92 ERA in his last nine starts. Giolito should be able to tame a weak Royals lineup that ranks in the bottom 10 in runs and is without their second-leading home run hitter, Hunter Dozier.

The Under is 6-0 in Giolito's last six starts.

Brad Keller is going for the Royals. The Under is 5-1 in his last six starts. Keller hasn't given up a home run in his last seven starts. The White Sox rank 23rd in runs and 25th in homers.

The weather forecast is for wind to be blowing in at eight mph, another plus for the Under.
