Arizona Form & Recent Results

Arizona heads into this matchup with some solid momentum on its side, coming in on a one-game winning streak while also having won four of its last five games before Saturday’s action. The Diamondbacks looked sharp in their most recent game, cruising to a convincing 9-1 win over the Rangers at home on Friday night. It was the kind of performance that showed just how dangerous Arizona can be when its lineup gets rolling. Ketel Marte played a big role in that offensive outburst, putting together a strong night at the plate by going 2-for-5 with two doubles, two runs scored, and three RBIs. The Diamondbacks’ offense as a whole did plenty of damage, finishing the game with 11 hits, two home runs, and 22 total bases, keeping constant pressure on the Texas pitching staff from start to finish.

On the mound, Merrill Kelly gave Arizona a steady start, working 4.1 innings while allowing just two hits and one earned run. He did issue three walks and struck out three batters, but he still helped put the Diamondbacks in a good position to take control of the game early. Overall, Arizona’s pitching staff combined to strike out eight Rangers hitters, throw 93 strikes, allow only five hits, and walk four batters in the win. With the postseason race heating up, the Diamondbacks are currently sitting in a strong playoff position, but they know there is still work to be done. As the regular season winds down, Arizona can’t afford to let winnable games slip away, especially against a Texas team they just handled comfortably. That makes Sunday’s series finale an important opportunity for the Diamondbacks to stay hot, avoid a setback, and continue building momentum for the stretch run.

Texas Form & Recent Results

The Rangers are heading into Sunday’s matchup desperately looking for a spark after hitting a rough patch, having dropped three straight games and three of their last five leading up to the weekend. Friday night was particularly brutal for the squad, as they suffered a devastating 9-1 blowout loss against the Diamondbacks right there in Phoenix. If there was any silver lining in that painful defeat, it was the performance of designated hitter Joc Pederson, who managed to go 2-for-5 at the plate while driving in the team's lone run with a solid double and a single.

Right now, Texas is hovering just a couple of games under the .500 mark, which puts them on track for a modest 79-win season. While the front office and fans haven't completely given up hope just yet, since a playoff berth isn't mathematically out of the question, the reality is that their postseason dreams are hanging by a very absolute thread. The team is running out of time to make a serious push, making Sunday afternoon's closing game against the D-backs at Chase Field an absolute must-win if they want to salvage their momentum and dust themselves off from Friday's disaster.
