PHILADELPHIA (Interstat) — In a wild back-and-forth affair that defied pregame projections and required bonus baseball, the Philadelphia Phillies authored a stunning late-inning comeback to walk off the Washington Nationals 6-5 in 10 innings on Wednesday afternoon at Citizens Bank Park.

A crowd of 37,469 watched as the Phillies, trailing by two runs entering the bottom of the ninth, rallied to tie the game before winning it in the 10th on a sharp RBI single by Justin Crawford, capping a chaotic finish that saw both teams’ records level at 3-3.

The game’s most critical sequence unfolded in the bottom of the ninth inning with the Nationals clinging to a 5-3 lead. After two quick outs, Trea Turner sparked the rally with a single. Kyle Schwarber worked a walk, and after a fly out, Alec Bohm walked to load the bases. Pinch-runner Dylan Moore entered for Schwarber. Edmundo Sosa then lined a single to left field, scoring Turner and Moore to tie the game when Nationals left fielder James Wood’s throwing error allowed the tying run to cross and the other runners to advance. The Phillies loaded the bases again with another walk but could not push across the winning run, sending the game to extra innings.

Washington squandered a prime chance in the top of the 10th, with CJ Abrams lining into an inning-ending double play. In the bottom half, facing Nationals reliever Cole Henry, Brandon Marsh began the inning as the automatic runner on second base. J.T. Realmuto singled, moving Marsh to third. Crawford then delivered the game-winning hit, a ground ball through the right side, scoring Marsh and sending the home crowd into a frenzy.

The victory was a stark contrast to the game’s early and middle chapters, which were dominated by strong starting pitching. Phillies left-hander Cristopher Sánchez, the top star for Philadelphia, delivered a stellar performance, allowing one earned run on four hits over 5 1/3 innings while striking out seven. His counterpart, Washington’s Cade Cavalli, was equally effective, yielding just one run on five hits through six innings of work.

Philadelphia struck first in the opening inning. Trea Turner walked and scored on a Kyle Schwarber RBI double, though Schwarber was thrown out at third trying to stretch it into a triple. Washington answered in the second without the benefit of a hit, as a walk, a hit batter, another walk and a strikeout that produced a wild pitch allowed Joey Wiemer to cross the plate.

The Nationals took a 2-1 lead in the sixth when Jacob Young singled and scored on Drew Millas’ line-drive single off reliever Brad Keller. The game then appeared to break open in the top of the seventh. After a successful challenge turned a potential out into a Daylen Lile single, Joey Wiemer followed with another single. Shortstop CJ Abrams then launched a three-run homer to right-center field, giving Washington a commanding 5-1 lead and silencing the Philadelphia crowd.

The Phillies began their methodical climb back immediately. Realmuto led off the bottom of the seventh with a solo home run to center, cutting the deficit to 5-2. In the eighth, Bryce Harper launched a solo shot of his own to right-center, making it a 5-3 game.

The Nationals’ bullpen, which had been solid, faltered in the fateful ninth. Clayton Beeter was charged with the two runs that tied the game, setting the stage for Henry’s loss in the 10th. Jhoan Duran earned the win for Philadelphia with a perfect top of the 10th, including a strikeout.

Abrams finished 1-for-4 with the three-run homer for Washington, which collected 10 hits but went 2-for-10 with runners in scoring position. Realmuto led the Phillies’ 12-hit attack, going 2-for-3 with the homer, a walk, and two runs scored. Crawford was 3-for-5 with the game-winning RBI.

The result upended the pregame analytics, as Interstat’s game simulator had projected an 6-2 Washington victory, though its ELO system gave Philadelphia a 69.7% win probability. The combined 11 runs went over the posted over/under line of 8.5.

The thrilling win gave the Phillies the series victory, taking two of three from their National League East rivals after splitting the first two games of the set. Both teams now look ahead to their next series. The Nationals return home to host the Los Angeles Dodgers beginning Friday, while the Phillies embark on a road trip, starting with three games against the Colorado Rockies, also on Friday.
