Neither the Astros nor the Dodgers lead their respective division, but they're each +600 (bet $100 to win $600) to be the last team standing this year. The New York Yankees (+650) and Boston Red Sox (+700) follow closely behind.
The opinion in Vegas generally tracks with forecasts elsewhere. On Baseball Prospectus, the Astros own the highest World Series title odds (17.7 percent) and the Dodgers are second (13.3 percent). Houston is the top team on FanGraphs (21.7 percent) as well, with Los Angeles in third (14.7 percent).
The Astros are riding a nine-game winning streak and swept the red-hot Seattle Mariners in Seattle over the weekend.
The Dodgers are trending in the opposite direction. They defeated the Milwaukee Brewers 7-1 on Sunday to snap a six-game losing streak. Clayton Kershaw is making his 2019 debut Monday night against the Cincinnati Reds, which should provide a boost.
Bettors clearly remain confident in the Dodgers over the long term despite their shaky start, and the same is true of the Yankees. But one has to wonder whether New York falls down the pecking order this time next week.
Giancarlo Stanton, Miguel Andujar, Aaron Hicks, Gary Sanchez, Luis Severino, Dellin Betances and Troy Tulowitzki are all on the injured list. Betances is out for at least six weeks, while Severino won't throw a ball whatsoever for at least six weeks.
At full strength, the Yankees have one of MLB's best rosters. But they likely won't be able to cope with that number of injuries to key players.
