There are 14 teams that have been created out of expansion, which began with the addition of the Los Angeles Angels and Washington Senators II (now the Texas Rangers) in 1961. Seven of them have won at least one world championship. Among the other seven, there are two teams still alive in the bid for a world championship.
The Washington Nationals (created as the Montreal Expos in 1969) eliminated Milwaukee (expansion 1969) in the NL Wild Card on Tuesday and advance to the NL Division Series against the Dodgers beginning Thursday. The Tampa Bay Rays, meanwhile, will look to advance from the AL Wild Card on Wednesday night against the A's in Oakland.
The Nationals are in the post-season for the sixth time -- the fifth since 2012. By winning the Wild Card game on Tuesday, the Nationals have advanced in the post-season for only the second time.
In 1981, when they were the Montreal Expos, they defeated the Phillies in the Division Series, but then lost to the Dodgers in the NLCS.
In four of the five series they have been eliminated, they have lost the fifth and final game of a best-of-five series.
The Brewers had made a strong charge to overtake the Cubs and claim an NL Wild Card spot in the post-season, winning 21 of 25 games going into their regular-season finale in Colorado, where the Rockies swept them in a three-game series. It was a prelude to the loss to the Nationals in the Wild Card game on Tuesday, Washington scoring three times in the bottom of the eighth for a 4-3 victory.
Brewers closer Josh Hader was the victim of the Nationals' game-winning rally, giving up three runs, two earned, on two hits, a walk and a hit batter. The Nationals have given Hader more problems than any other franchise. He has seven career appearances against the Nationals, and is 0-2, having failed to convert three of four save opportunities.
The Brewers were making thier sixth post-season appearance. They have been eliminated in the first round of the post-season in four of the six years.
