One of the Miami Marlins' top pitching prospects made his first big league start on Friday. And while most of the numbers from this outing won't necessarily stand out, the young hurler certainly showed some flashes of his potential. Left-handed pitcher Robby Snelling, Miami 's No. 2 prospect and MLB Pipeline 's No. 31 overall prospect for 2026, threw five innings in the Marlins' 3-2 loss to the Washington Nationals on Friday. The 22-year-old gave up three runs on five hits and four walks, while striking out two in 86 pitches thrown. Washington did all of their damage against Snelling in the first inning. The southpaw began his MLB debut by striking out All-Star slugger James Wood on three pitches. The young lefty then gave up a double to Curtis Mead before punching out Brady House. But with two outs, CJ Abrams roped an RBI single and Jacob Young launched a two-run homer to give the Nationals all of the runs they'd need to come away with a win.
