Nationals’ Andrew Alvarez Wins MLB Debut, Ends Eight-Game Skid

On September 1, 2025, Washington Nationals rookie pitcher Andrew Alvarez made a remarkable major league debut, leading the Nationals to a 2-0 victory over the Miami Marlins and ending an eight-game losing streak. Alvarez, a 26-year-old left-hander drafted in the 12th round in 2021, pitched five scoreless innings, allowing only one hit and striking out four, becoming the first Nationals pitcher since the franchise's move to Washington in 2005 to throw at least five scoreless innings in his debut. Alongside Alvarez, catcher CJ Stubbs also made his MLB debut, marking a rare occasion where both pitcher and catcher debuted in the same game for the Nationals, a feat not seen since 2008. Stubbs contributed significantly by managing the pitching staff effectively, though he did not record a hit in the game. Alvarez's performance was characterized by excellent command and a balanced mix of pitches including sliders, fastballs, and curveballs, showcasing his ability to keep hitters off balance. The combined efforts of Alvarez, Stubbs, and the Nationals' bullpen, who pitched 13 scoreless innings over three games, helped secure the win and brought a rare moment of optimism to a struggling Nationals team.
