Washington Nationals Team Overview
Washington responded to their series-opening loss with nine hits and five runs. The hosts drew seven walks and consistently applied pressure with runners on base. The team currently sits third in their division and, with the victory, climbed back above the .500 mark. However, Mikolas's start with a 5.60 ERA means they can't rely solely on pitching-offensive support will once again be crucial.

Arizona Diamondbacks Team Overview
Arizona have won eight of their last 10 games before Saturday's defeat and remain second in the National League West Division. Yesterday, the visitors scored three runs and had plenty of chances, but the starting pitcher issued five walks. The Diamondbacks boast a deeper lineup and are well-equipped to capitalize on Mikolas' struggles. The key will be a cleaner pitching performance after a disappointing second game of the series.

⚾ Starting Pitchers
Miles Mikolas takes the mound for Washington with a 3-7 record, a 5.60 ERA, and 51 strikeouts. The right-hander rarely finishes challenging innings with strikeouts, often relying on solid defense to back him up.
Cole Drake will pitch for Arizona, holding a 0-0 record, a 1.80 ERA, and five strikeouts. The lefty has limited experience at this level, making his stats not yet stable. However, he faces a more favorable matchup in this starting duel.
⭐ Editor’s Prediction
Washington have confidently taken their second meeting and hold the upper hand in their last 10 head-to-head matchups. However, Mikolas starting poses a significant risk for the hosts right from the early innings. Arizona boast a stronger seasonal record and come into the game with an offense capable of exploiting a pitcher with an ERA of 5.60. Drake remains a relatively unknown factor, but he doesn't need to completely shut down the hosts-just maintain a level scoreline until mid-game. The visitors should find more opportunities against the opponent's starting pitcher and look to regain the initiative following yesterday's defeat. Our pick here is for an Arizona Diamondbacks victory.
