Diamondbacks' Drey Jameson: Optioned to Triple-A

Jameson was optioned to Triple-A Reno on Monday.

He'll cede his spot on the 26-man active roster to Tommy Henry, who who was called up from Triple-A in advance of his start Monday against the Royals. Jameson has labored in his last two starts, lasting just one inning in his most recent outing Sunday. He should join Reno's rotation to work on his efficiency. Though Henry is filling Jameson's spot in the rotation for now, prospect Brandon Pfaadt could eventually occupy the spot if Henry falters in his return to the big leagues.
