Chicago White Sox right-hander Lucas Giolito followed his first career All-Star appearance by losing to the Kansas City Royals for the first time in his career on Monday night.

Giolito chalked his struggles up to the oddities of the midseason break before aiming for a return to form Saturday in a start against the Tampa Bay Rays in St. Petersburg, Fla.

"Coming off the All-Star Game just going out and trying to blow it out for one inning and then off a long time between starts, there's going to be games when I don't have my best velocity," Giolito said. "And that's when I really have to do a better job of executing. I think my fastball command kind of got worse as (Monday) night went on. That's just part of it. Just need to get back in the gym, get my legs right, and we'll see it creep back up."
