Don Drysdale held the scoreless innings record before Hershiser; it was controversial because he hit a batter (against the Giants)  with the bases loaded, which would have ended the streak, but the umpire ruled the batter didn't try to get away from the pitch and refused to award him first base.

And coincidentally Hershiser's streak was also preserved via a controversial overturned call vs the Giants. SF scored a run during a force out at second base followed by an overthrow to first base. But Paul Runge ruled that Brett Butler had interfered with the fielder at second and declared an inning ending double play instead. This was during the 43rd inning of Hershiser's streak; the Drysdale call was during the 45th inning of his streak.
