Dennis Martínez's perfect game
On July 28, 1991, Dennis Martínez of the Montreal Expos pitched the 13th perfect game in Major League Baseball history, blanking the Los Angeles Dodgers 2-0 at Dodger Stadium. A native of Granada, Nicaragua, Martínez became the first pitcher born outside of the United States to pitch a perfect game. (He has since been joined by Venezuela native Félix Hernández, who pitched a perfect game in 2012.) The perfect game also made the Dodgers the first team to be on the losing end of consecutive perfect games; they have since been joined by the Tampa Bay Rays, who were the losing team in Mark Buehrle's perfect game in 2009 and Dallas Braden's perfect game the following year.
The perfect game is the last of four no-hitters in Montreal Expos history, Bill Stoneman having pitched two, in 1969 (the franchise's inaugural season, and only nine games into its history) and 1972, and Charlie Lea in 1981. After the 2004 season, the franchise moved to Washington, D.C., where it became the Washington Nationals, and would not record the first no-hitter in its Washington history until Jordan Zimmermann no-hit the Miami Marlins on September 28, 2014.
Martínez's mound opponent, Mike Morgan, was perfect himself through five innings, the latest the opposing starter in a perfect game has remained perfect.
Two days earlier, Martínez's teammate, Mark Gardner, no-hit the Dodgers through nine innings but lost the no-hitter, and eventually the game, in the tenth. The Expos would have become the first team to throw a perfect game and an additional no-hitter in the same series, and would have joined the 1917 St. Louis Browns as the only teams to throw two no-hitters in the same series. On consecutive days of that season, May 5–6, Ernie Koob and Bob Groom no-hit the eventual World Champion Chicago White Sox.
Dodger Stadium, the site of Sandy Koufax's perfect game in 1965, became the first stadium to witness two perfect games; it has since been joined by Yankee Stadium, Oakland-Alameda County Coliseum and Safeco Field.
