Gerardo Parra #88 of the Washington Nationals celebrates with the trophy after winning the National League Championship Series against the St. Louis Cardinals at Nationals Park on Oct. 15, 2019, in Washington, DC. But it's hard to think of many guys better than that trio to kick off a World Series." The Astros are in their third World Series in franchise history, having reached the series in 2005 and winning it all in 2017.
