MLB Postseason Update
We are inching closer to the Fall Classic and in fact, one National League team could clinch a trip to the World Series as early as Friday night. The Los Angeles Dodgers can complete a four-game sweep over the Milwaukee Brewers. Two-way superstar Shohei Ohtani will be on the mound for Los Angeles as Milwaukee looks for any signs of life in the NLCS.
Meanwhile, the ALCS is a back-and-forth affair. The road team has won all four games so far in this series. Will that trend continue on Friday night? Underdog will have a ton of different ways to get in on the action during the MLB Postseason, but it all starts with this $100 sign-up bonus.
