The Diamondbacks have placed right-hander Kendall Graveman on the 15-day injured list (retroactive to June 8) due to a right hip impingement, and Christian Montes De Oca has been called up from Triple-A to fill his roster spot. Graveman, who struggled in his last outing, saw his ERA rise from 2.45 to 8.64 after allowing six earned runs in one inning against the Reds; he has struggled with more walks than strikeouts and decreased groundball rates. Additionally, righty Cristian Mena was placed on the 15-day IL with a teres major strain, expected to keep him out for weeks, further impacting the D’Backs’ pitching staff.
