Washington Nationals vs. Pittsburgh Pirates preview
The Pirates roll into Washington with their offense sputtering at just 3.6 runs per game, ranking dead last in MLB, while the Nationals counter with a pitching staff that's been equally generous, surrendering 5.61 runs per nine innings.
Mitch Keller takes the ball for Pittsburgh carrying a concerning 4.51 ERA and 1.384 WHIP into this late-season matchup, facing off against Washington's Brad Lord, who's managed a more respectable 4.21 ERA across his 109 career innings.
The betting market clearly favors the Pirates despite their offensive woes, with Pittsburgh sitting as heavy -182 favorites, suggesting oddsmakers believe Keller can exploit a Nationals lineup that's managed just a .245 team batting average.
Washington's bullpen has been one of their few bright spots with a solid 66% save percentage, but their fielding has been shaky with 80 errors and a defensive efficiency that ranks 28th in the majors.
Both teams are playing out the string with little to play for beyond pride, as Pittsburgh sits at 64-82 and Washington at 60-85, but division rivalry games can still produce unexpected fireworks in September.
The over/under sits at 8.5 runs, which feels generous given Pittsburgh's anemic offense, but Washington's porous pitching staff has a way of making even the weakest lineups look dangerous.
