August 30, 1984 Mariners 2, Tigers 1 (87-47)
Starters Jack Morris and Jim Beattie both took shutouts into the eighth inning before either scored. In the bottom of the eighth, the wheels came off the wagon for Morris though. Spike Owen led off with a walk. Then second basemen Jack Perconte laid down a bunt, and according to Retrosheet.org, Morris dove for the pop up, missed it, then three the ball into rightfield while sitting down. To make matters worse, Kirk Gibson then threw the ball into the Mariners dugout trying to throw Perconte out at third base. So the Mariners scored both of their runs without even getting a hit.
In all, Morris pitched a great game though. He went the distance, gave up only four hits, and struck out eight.
The Tigers tried to answer in the ninth. Barbaro Garbey drew a lead off walk before Chet Lemon grounded out. Larry Herndon then also drew a walk to put runners at first and second. Howard Johnson singled to load the bases, but Lou Whitaker struck out to leave it up to Alan Trammell. Tram came through by drawing a walk and driving in a run, but Kirk Gibson grounded to second to end the game.
