The Mets beat the Orioles, 5-3, at Shea Stadium on today's date in 1969 to win their first World Series title when the final out was squeezed by Cleon Jones in left field after a drive off the bat of Davey Johnson.
The Miracle Mets, with a starting rotation anchored by Tom Seaver and Jerry Kossman, had never won more than 73 games during the first seven years of their existence. Then 1969 happened, when they overtook the Cubs late in the season and won the NL East. After a 100-win regular season, the Mets swept the Braves in the best-of-five NLCS.
The Orioles were heavily favored in the World Series, but after losing Game 1 in Baltimore, the Mets reeled off four straight wins to hoist the trophy... after some absolute bedlam on the field.
