NL playoff matchups pending Mets-Braves makeups on Monday. AL set with Astros-Tigers and O’s-Royals

NEW YORK (AP) — The baseball season is going extra innings. While the American League playoff picture cleared up Sunday, the National League remained muddled heading into what was supposed to be an off day before the postseason. Houston hosts Detroit, and Baltimore is at home against Kansas City in best-of-three AL Wild Card Series starting Tuesday. The Astros-Tigers winner faces AL Central champion Cleveland in a Division Series starting Saturday, and the Orioles-Royals winner plays the AL East champion New York Yankees. The NL is still uncertain because of two rainouts last week, with the New York Mets, Arizona and Atlanta vying for the final two wild-card spots in the 12-team playoffs. The Mets traveled back to Atlanta on Sunday and will play a makeup doubleheader Monday against the Braves.
