The Pirates did not have a hit on Sunday, but because they were the home team and scored a run in the eighth inning (three walks and a one-out fielder's choice), they did not have to bat in the ninth. Therefore, this game is not an official no-hitter.
This is extremely stupid. The game was played to an official completion and the Reds, although they lost, did not allow a hit . . . so that's a no-hitter. It's pretty much the definition of a no-hitter. It should be added to the official list, with a notation that the no-hit team batted in only eight innings.
