Major League Baseball's regular season will wrap up Wednesday. There won't be much drama to be found as it pertains to the complexion of the playoff field. All 12 teams who will advance to the tournament have already clinched their spots and their seeds. Still, that doesn't mean playoff teams are left with nothing to think about between now and the official start of the postseason on Friday.

Rather, several teams have tough decisions to weigh about their postseason rosters. Some of those questions stem from health woes, and others from performance-related issues. Either way, CBS Sports has highlighted five notable players below whose statuses for their clubs' initial playoff rosters remain in doubt heading into Game 162. (Do note that the players are presented in alphabetical order.)

1. Francisco Álvarez, C/DH, New York Mets

Álvarez made his big-league debut only last weekend, but he's eligible for the postseason and the Mets might deem him a necessary addition to their playoff roster. Part of that is because Álvarez is a talented young catcher with game-changing power; part of it is because the Mets lack capable right-handed bats. The Mets are expected to be without starting outfielder Starling Marte for at least the Wild Card Series because of a broken finger. Deadline addition Darin Ruf is also injured, and he hasn't been effective since arriving in town. That leaves Álvarez as arguably the best candidate to serve as the Mets' designated hitter (or pinch-hitting option) when they face a lefty.
