Oct. 16, 1969: No playoff bids in team history. No winning seasons, even. Therefore, no chance at doing anything in 1969.
By now we know: No way. And so, on this day 43 years ago, the New York Mets clinched the franchise's first World Series title with a 5-3 win over the Baltimore Orioles at Shea Stadium. Said series ended up 4-1, capping off a 100-win season for the Miracle Mets, powered by the likes of Tom Seaver, a young Nolan Ryan (used primarily in relief) and World Series MVP Donn Clendendon.
Not bad for a team given 100-to-1 odds to win it all before the season started.
