Diamondbacks Can Win If…
They extend their power surge. Arizona ranks 3rd in slugging percentage (.440) and 5th in home runs (166), with Ketel Marte and Blaze Alexander going deep in Tuesday’s 3–2 win.
Zac Gallen (9–12, 5.31 ERA) has been trending in the right direction, posting a 2.25 ERA over his last two starts. If he can neutralize the Rangers’ middle of the order, the Diamondbacks can ride their hot bats to a road series win.
Rangers Can Win If…
They lean on their elite pitching staff. Texas leads MLB with a 3.33 ERA and a .226 batting average against. Merrill Kelly (9–7, 3.38 ERA) has the arsenal to quiet Arizona’s bats — but he’ll need to avoid the control issues that plagued him in his last outing (5 walks vs. Philadelphia).
Corey Seager and Marcus Semien will be key run producers, and Texas’ top-five stolen base ranking could help manufacture runs in a low-scoring game.
