Major league baseball final standings
- April 6 – Against the Atlanta Braves at Wrigley Field, Chicago Cubs pitcher José Guzmán has a no-hitter broken up with two out in the ninth by an Otis Nixon single. The hit is the only one Guzmán allows in a 1-0 victory. The no-hitter would have been first by a Cubs pitcher since Milt Pappas in 1972.
- April 8 – Against the New York Yankees at Cleveland Stadium, Carlos Baerga of the Cleveland Indians becomes the first player to hit a home run from both sides of the plate in the same inning. In the Indians' nine-run seventh inning, Baerga begins the scoring with a two-run home run against left-hander Steve Howe. He concludes the scoring by homering again, this time against right-hander Steve Farr. The Indians defeat the Yankees, 15-5.
- April 22 – At the Kingdome, Chris Bosio of the Seattle Mariners no-hits the Boston Red Sox 7-0. He walks the first two batters of the game, Ernest Riles and Carlos Quintana, and after the latter is retired on Mike Greenwell's double play grounder, no other Red Sox reaches base. Mariners shortstop Omar Vizquel makes the last dramatic out by bare-handing Riles' high-chopper over the mound.

Craig Biggio is at second base for the NL; an All-Star one year earlier as a catcher, he is the first player ever to make the team at those two positions. A highlight of the game is Randy Johnson firing a 95-MPH fastball over John Kruk's head. Kruk bails out on the next two pitches, then says, "He's going to kill somebody."

With the delay, McGriff is able to be inserted into the starting lineup and hits a game-tying two-run homer in the sixth inning, helping the Braves rally from a 5-0 deficit to win 8-5. The Braves trail the San Francisco Giants in the National League West Division by 9 1⁄2 games at that point, and this game is seen as the game that sparks their run to the division title.

With two outs, the Yankees' Mike Stanley pops out to end the game, however the play is called a no play when home plate umpire Tim Welke is forced to call time when a fan runs out onto the field just as the pitch is delivered.
