On this day in 1960, Camilo Pascual of the Washington Senators (later the Minnesota Twins) set an opening day record with 15 strike-outs.
The opening day record still stands. Randy Johnson came close twice with 14.
Pascual won 100 games over a 6-year period and led the AL in complete games and strike outs 3 times. He retired with 176 wins and a 3.63 ERA.
He pitched for the 1965 AL champs Twins. Unfortunately, injuries limited him that season. He did start game 3 of the World Series against the Dodgers.
