Washington Nationals vs. Pittsburgh Pirates preview
Two clubs limping toward the finish line meet at Nationals Park on Saturday, with Pittsburgh's 64-82 record barely edging Washington's dismal 60-85 mark in what amounts to a battle for draft positioning.
The Pirates arrive with one of baseball's worst offenses, ranking dead last in runs per game at 3.6 while managing just a .231 team batting average that screams rebuilding year.
Young right-hander Bubba Chandler gets the nod for Pittsburgh despite a rough 7.61 ERA through limited big league action, facing off against Washington's Andrew Alvarez, who has shown promise with a 1.96 ERA in early outings.
The Nationals offer slightly more pop with 140 home runs compared to Pittsburgh's 104, but their pitching staff ranks among the league's worst with a 5.30 ERA that has them surrendering nearly six runs per game.
Both bullpens have struggled mightily in save situations, with Pittsburgh converting just 58.9% of their chances while Washington sits marginally better at 66.0%.
With playoff hopes long since buried for both sides, this matchup becomes about evaluating young talent and building toward 2026, making it a perfect laboratory for prospects like Chandler to gain valuable experience.
