In a Sunday series finale against the Nationals in Washington, the Phillies’ bats came alive, winning 11–9 thanks to 12 hits including home runs from Nick Castellanos and Alec Bohm. After dropping two of three games to the Cincinnati Reds, Philadelphia ended a 10-game road trip with a 6-4 record, and that victory helped them salvage a four-game split with the Nats.

The Mariners, however, have had mixed luck thus far on their Mid-Atlantic tour, dropping two of three games to the Baltimore Orioles and the Mets. However, Seattle is presently holding one of the three Wild Card spots in the American League and is 1.5 games behind the Houston Astros in a contest for the West Division.
