Andrew Alvarez gives Washington a credible starting-pitching case, but Michael McGreevy’s latest outing and the Nationals’ relief results limit the edge.
The Washington Nationals visit the St. Louis Cardinals on September 19 in this 2026 MLB matchup, scheduled for 7:15 p.m. ET. Both Covers and the Associated Press identify Washington left-hander Andrew Alvarez and St. Louis right-hander Michael McGreevy as the starters.
Alvarez enters with a 3.35 ERA, compared with McGreevy’s 3.83. On September 12 against the Angels, Alvarez delivered seven scoreless innings, allowing one hit with eight strikeouts. His four walks remain a caution: that outing combined excellent run prevention with opportunities for trouble.
McGreevy supplies meaningful counterevidence to a Washington pick. He allowed one earned run on three hits over six innings against the White Sox on September 13, striking out six and walking three. He also held Washington to one run over six innings on April 8. Those performances make it difficult to portray this as a decisive pitching mismatch.
SportsJaw lists Washington at +110 and St. Louis at -130 on the moneyline. Washington won the September 18 series opener 9-1, but one offensive outburst provides limited support for projecting another productive night.
The Nationals’ bullpen allowed seven earned runs across 9⅓ innings in its last three games. That recent relief performance weakens the case for trusting an early Washington lead.
The total is 8.5, with over 8.5 (-120) and under 8.5 (+100). Although the 4-3 projection falls below that number, bullpen uncertainty and the absence of supported lineup and hitting-split information leave insufficient support for an under recommendation.
The selection is Washington Nationals moneyline (+110), with a projected 4-3 win and low confidence. Alvarez’s lower season ERA and latest scoreless start support a slight lean at plus money. McGreevy’s strong latest outing and Washington’s bullpen risk keep the advantage fragile.
