Arizona’s Zac Gallen has struggled on the road this season. He owns a 5.08 ERA and is facing an Angels team hitting .263 over their last 10 games. Arizona won the first two games of the seres, but are still only hitting .232 over their last seven days. Left-hander Reid Detmers has only allowed two earned runs in his last 19.2 innings at home.

Arizona's Zac Gallen is the NL Cy Young favorite, but he's been vulnerable on the road (5.08 ERA) and his profile includes some obvious regression signs. He's allowing the highest hard-hit rate (45 percent) and average exit velocity (91.1 mph) of his career, and his expected ERA is 3.81 compared to his actual 3.02 ERA. Angels lefty Reid Detmers has been nearly unhittable over his past four starts, as he's found his wicked slider from last year. Back the Angels to avoid the sweep.

Angels lefty Reid Detmers has dominated in his last four starts, fanning 34 while allowing three earned runs on 12 hits over 25.2 innings. Arizona hits lefties worse than righties (.734 OPS compared to .778). Diamondbacks ace Zac Gallen has been nearly unhittable at home but has a 5.08 road ERA. He has given up a homer in five straight starts, including last Tuesday when he allowed four earned runs over six innings vs. Tampa Bay. In my simulations, the Angels are winning Sunday's game 59 percent of the time.
