The Mariners will promote standout pitching prospect Logan Gilbert, according to Jeff Passan of Gilbert will start their game against the Indians on Thursday, per Ryan Divish of the Seattle Times.

This is the second major promotion coming this week for Seattle, which is also set to call up elite outfield prospect Jarred Kelenic prior to Thursday’s contest. The Mariners and their fans will get their first major league looks at two players they hope will be part of the solution in Seattle for the long haul.

Like Kelenic, Gilbert was part of the first-round class of 2018. The Mariners took the right-hander 14th overall out of Stetson University, where Cy Young winners Jacob deGrom and Corey Kluber attended. And although Gilbert didn’t pitch professionally that season because of mononucleosis, he has since dominated minor league competition.
