Liberatore will start Friday against the Guardians at Progressive Field, Derrick Goold of the St. Louis Post-Dispatch reports.
Though Liberatore made his last appearance out of the bullpen Sunday against the Dodgers, manager Oliver Marmol previously confirmed that the 23-year-old lefty would get another start during the team's weekend series in Cleveland. Liberatore now has a date set in place for his next turn, and he'll get the chance to build on a strong showing in his first start of the season versus Milwaukee on May 17, when he worked five scoreless innings and struck out six. If he's able to hold his own against Cleveland, Liberatore should have a good chance of sticking around with the big club as the sixth member of the rotation.
