When Brian Matusz won on Tuesday, he became the fifth Baltimore rookie to win his big-league debut this season, a feat unrivaled in modern baseball history. Only one other team — the 1888 Chicago White Stockings, who later became the Cubs — has managed to equal that achievement, giving the Orioles an interesting footnote in the game’s annals.
Koji Uehara, Brad Bergesen, Jason Berken and David Hernandez have also won their debuts this season, and Baltimore had a near-miss in a no-decision for Chris Tillman.
Rookie Matt Wieters, who helped usher Matusz through his debut, had an interesting quip. “That’s when they started baseball,” he said of 1888. “So everybody was debuting.”
