The Baltimore Orioles are calling up top prospect Grayson Rodriguez and he will make his debut Wednesday against the Texas Rangers, according to sources.

The right-hander is ranked as the No. 12 prospect in baseball by ESPN's Kiley McDaniel.

Rodriguez, 23, struggled with a 7.04 ERA in 15 1/3 innings during spring training. He allowed 14 runs (11 earned) in his final 10 2/3 innings of spring and was optioned to Triple-A Norfolk.

However, a foot injury to Kyle Bradish on Monday required Tyler Wells to pitch in relief instead of making his scheduled start Tuesday. Kyle Gibson moved up a day in the rotation to pitch Tuesday, leaving a spot open for Rodriguez.
