CHICAGO — Kyle Harrison was never himself during spring training, tasked with recovering from both a nagging shoulder injury and an illness-induced weight loss. A month into the season, Harrison is back up with the Giants. As a reliever.

The San Francisco Giants recalled left-hander Kyle Harrison on Monday, in advance of a three-game road series against the Chicago Cubs, while right-hander Lou Trivino was designated for assignment.

Kyle Harrison was called back up from Triple-A on Sunday, but the San Francisco Giants don't appear comfortable slotting the lefty back into their rotation just yet.
