St. Louis Cardinals at Arizona Diamondbacks

Less than 24 hours after they played a sloppy, mistake-filled game, the Diamondbacks rebounded behind the pitching of Brandon Pfaadt and the hitting of Nolan Arenado to beat the Cardinals, 5-3, on Saturday afternoon at Chase Field. The win evened the series at a game apiece and gave the D-backs their 50th victory of the season ahead of Sunday's rubber match. Here are some takeaways from the game: **Pfaadt figuring it out** It hasn't been the easiest of seasons for Pfaadt, who opened the year in the rotation and struggled in his first three starts. When Merrill Kelly was then activated off the injured list, Pfaadt was sent to the bullpen and eventually to Triple-A Reno. While with the Aces, Pfaadt tweaked his mechanics. He got rid of the over-the-head part of his delivery and moved back to the first base side of the pitching rubber. The difference in results has been startling. In his first three starts of the year, he had a 5.94 ERA. In 10 relief appearances he had a 5.91 ERA. In four starts since returning from Reno, Pfaadt is 4-0 with a 2.14 ERA.
