Red Sox rookie pitcher Ryan Watson made his MLB debut on Saturday, allowing three walks while striking out one over 2.1 hitless and scoreless innings in a 6-5 extra-innings loss to the Cincinnati Reds. Watson, a Rule 5 pick, entered the game in the sixth inning with the Red Sox trailing by two runs and two runners on base. After a shaky start that included two overturned strikeouts, Watson settled in to throw scoreless seventh and eighth innings.

Why it matters

Watson's impressive debut, despite the Red Sox's loss, provides an encouraging sign for the team's bullpen depth as they look to bounce back from a disappointing 2025 season. As a Rule 5 pick, Watson will need to remain on the active roster all season or be offered back to his former team, making his early success crucial.

The details

In his MLB debut, Watson entered the game in the sixth inning with the Red Sox trailing the Reds 6-4. After walking the first batter he faced, Watson thought he had struck out Eugenio Suarez twice on called third strikes, only to have both calls overturned on challenges. Watson eventually got Suarez to ground out to second base, then threw scoreless seventh and eighth innings to keep the Red Sox within striking distance.
