The Cubs are selecting righty Robert Gsellman onto the big league roster, as Meghan Montemurro of the Chicago Tribune was among those to relay. Drew Smyly, who had been scheduled to start this evening’s game against the White Sox, has been placed on the bereavement list to open active roster space. Southpaw Locke St. John has been designated for assignment in a corresponding 40-man roster move.

Gsellman inked a minor league deal with Chicago during Spring Training. He’d been non-tendered by the Mets, with whom he had spent his entire career. The Southern California native broke into the majors late in the 2016 season and flashed some potential as a starter during his rookie campaign. He struggled over 119 2/3 innings the following year, though, and he spent the next few seasons working out of the bullpen.

In the four years since moving to relief, Gsellman has tossed 186 1/3 innings of 4.73 ERA ball. His 19.2% strikeout rate was below-average, but he had a solid 8.1% walk percentage and induced ground-balls at an above-average 47% clip.
