HP Umpire Mark Ripperger called Athletics pitcher Mike Fiers' no-hitter against the Cincinnati Reds, the first of 2019, at a blistering 100% accuracy rate for Oakland's starter. Rip was joined for Tuesday's game at Oakland Coliseum by 1B Umpire Jeff Kellogg (crew chief), 2B Umpire James Hoye, and 3B Umpire Brian O'Nora.

This is Ripperger's first career no-hitter and the first of the 2019 season.
