Most of Major League Baseball's drama in the final week of the regular season resides in the American League West.
The Texas Rangers, Houston Astros and Seattle Mariners are all still alive for the AL West crown and the final two wild-card positions.
Texas gained a significant advantage with a weekend sweep over Seattle. The Rangers enter the week with a 2.5-game lead over the Astros and a three-game edge over Seattle.
The Rangers could have the division title wrapped up, or be close to it, by the time they reach Seattle on Thursday.
Seattle has the most to gain in the next seven days, as it plays host to the Astros and Rangers at T-Mobile Park.
