How to bet the NLCS and ALCS

What a difference a week makes.

In our MLB divisional series betting preview last Thursday, the four 9-2 co-favorites in the World Series futures at the Westgate Las Vegas SuperBook were the four favorites in the divisional series: the Detroit Tigers, Los Angeles Angels, Los Angeles Dodgers and Washington Nationals.

A week later, they are all gone, upset in respective order by the Baltimore Orioles (plus-135 as a series underdog despite having a better record this season and home-field advantage), Kansas City Royals (plus-175), St. Louis Cardinals (plus-165) and San Francisco Giants (plus-140). And none of them even had to go to a fifth game. Who woulda thunk it?

Well, I got it at least half right as I picked the Orioles and Giants to win their series in that piece. I wasn't as confident in the Royals and Cardinals, but at least I didn't bet against them.

Baltimore is now the 2-1 World Series favorite at the Westgate. They are a minus-135 favorite over Kansas City in the American League Championship Series that starts Saturday and would have home-field advantage in the World Series by virtue of the AL's 5-3 victory in the All-Star Game on July 15 at Target Field in Minneapolis. St. Louis, which is a minus-135 favorite in the National League Championship Series, is the 5-2 second choice, with Kansas City and San Francisco both at 3-1.
