What happened: CBS Sports' latest MLB Power Rankings reflect a top-heavy league led by the Atlanta Braves and Los Angeles Dodgers. The Philadelphia Phillies and Cleveland Guardians both climbed into the top five, while the New York Yankees dropped following a major injury blow.

Why it matters: The Yankees' slide coincides with Aaron Judge's rib injury, which is expected to sideline the star for at least a month. Meanwhile, the Phillies have found new life under manager Don Mattingly, going 26-11 to solidify their postseason positioning.

What to watch: Watch for the Yankees' ability to stay afloat in the AL East race without their captain. The surging Phillies face a critical stretch to prove their top-five status is sustainable.
