Five Major League Baseball playoff spots remain open with four days left in the MLB regular season. Thursday features another slate of crucial games, including the opener of a four-game series between the Rangers and Mariners that will go a long way in determining the AL West and AL wild-card races. The MLB playoff picture is shaping up with seven teams in the field, and the Rangers and Diamondbacks could join them Thursday.
The Orioles also enter Thursday needing just one win to secure their first AL East title since 2016. Baltimore hosts the Red Sox at Camden Yards to kick off their final series of the regular season. In other AL action, the Blue Jays -- still in control of their playoff destiny -- host the Yankees and can lower their magic number to two with a victory.
In the National League, the top four seeds are set with the Braves, Dodgers, Brewers and Phillies locked into place. That leaves the final two wild-card spots open. The Diamondbacks are in control of the No. 5 seed, but their loss to the White Sox on Thursday means Friday is the earliest they can clinch a playoff spot. Further down the NL wild-card standings, the Marlins and Cubs enter the day with the same record, but Miami owns the tiebreaker and controls its own fate.
