Zach Eflin’s Major League debut against the Toronto Blue Jays did not go well today. In fact, it was the worst debut in Phillies history and one of the worst in baseball history.
Eflin missed with his location all day against a potent Jays lineup, which resulted in nine runs (eight earned) on nine hits with three walks and two strikeouts in just 2 2/3 innings. His ERA is 27.00 and he gave up three home runs in less than three innings of work.
It was historically bad. Eflin’s Game Score of 5 was the sixth-worst debut in Major League history, and the worst since Detroit’s Lou North in 1913.
