Chen will make his next start Friday against the Indians, MLB.com reports. After his scheduled start Tuesday was rained out, Chen will wait a few more days until taking the hill. The O's will send Chris Tillman to the mound Wednesday, while Ubaldo Jimenez and Kevin Gausman will pitch Saturday and Sunday, respectively. Baltimore is off Thursday. In his last start, Chen allowed eight hits and four earned runs over 5.0 innings in a loss to the Blue Jays.
