The MLB postseason kicks off Saturday with the League Division Series, marking the first time the top two seeds in each league face off this October. The winners will progress to the League Championship Series, vying for a World Series spot.

Each series has its unique X-factor, highlighting key aspects that could influence outcomes. For instance, the Kansas City Royals' speed contrasts with the New York Yankees' slower approach, while the San Diego Padres' pitching velocity may give them an edge over the Los Angeles Dodgers.

The New York Mets and Philadelphia Phillies both rely heavily on fastballs, showcasing a strength-on-strength matchup, while the Detroit Tigers and Cleveland Guardians could see bullpens play a pivotal role due to their reliance on relief pitchers.
