Baseball's Fall Classic kicks off Tuesday night, and Las Vegas oddsmakers are predicting a fairly tight matchup between the National League's Los Angeles Dodgers and the American League's Houston Astros. The Dodgers are currently listed as a -165 favorite to snatch their first world title since 1988, according to sportsbook Bovada.lv, with the Astros a slight underdog at +145 to capture what would be the sole title in the franchise's history. The Astros last appeared in 2005, but fell to the Chicago White Sox in four games.
