Houston is again the odds-on favorite in the division it has won each of the last six full MLB seasons since the Rangers finished on top in 2016. The Astros won their regular season finale last Oct. 1, matched Texas at 90-72, and won the AL West since they were 9-4 head-to-head. Seattle Mariners should be better offensively with the additions of Mitch Garver, Mitch Haniger, Jorge Polanco and Josh Jung.
