Saturday's Nationals win ended like this:
Sunday's ended like this:
And Monday's concluded like this:
That means the Nationals have now won seven games in a row overall and are a season-high 17 games over .500. The Braves won Monday night, so the lead is still six games in the NL East. At 70-53, Washington boasts the best record in the NL.
As far as three straight walkoff victories, that's the second time this season that a team has pulled it off. The Rays did so May 22-24. The Blue Jays recently did it twice in a row. The Red Sox did it two straight on July 9-10, just as the Rockies and did in May, the Cardinals did in July and Giants did in April. The Padres had two straight walkoff wins in both early May and early August. The Pirates did so in the first two games of the season and the Rangers did in games two and three. The Marlins did it three times in four games in early May.
But only two have strung together three straight.
The record for consecutive walkoff wins is five, which was done by the 1986 Houston Astros, who won the NL West with a 96-66 record. The Nationals have six games left on their homestand, so it's at least possible (albeit unbelievably unlikely) to run this thing to nine games.
