Bosman threw his no-hitter against the Oakland A’s on July 19th of 1974, allowing not only no hits but also no walks, a perfect game eluding him because of an error by the pitcher himself in the top of the fourth when he threw a check-swing slow-roller wide of first base off the bat of Sal Bando.
By the time the game was over, Bosman finished with only four strikeouts, not over-powering the eventual World Champs, but throwing strike after strike, just keeping his pitches in the strike zone batter after batter.
It was only Bosman’s second win of the year at this point, and he would go on to finish 1974 with a record of 7-5 with a 4.10 earned run average over 25 appearances.
Ironically, in just the very next year, 1975, Bosman would join the A’s, helping them to another division championship when he’d go 11-4 after an in-season trade.
