Kremer (forearm) threw a bullpen session Tuesday, Matt Weyrich of The Baltimore Sun reports.
Kremer has progressed more quickly than expected after exiting his last start over the weekend after a liner hit his right forearm. Orioles manager Brandon Hyde previously indicated it was unlikely that Kremer would be ready for his next turn Friday versus the Rays, but it appears it hasn't been ruled out. The club will see how Kremer feels Thursday before making a determination.
