So much went right for the Yankees this weekend — but not everything.

The Yankees should not plan on four-run eighth innings to escape with victories over playoff teams like the two they just pulled off Saturday and Sunday.

They probably should not count on winning too many games when DJ LeMahieu and Joey Gallo drop proverbial cans of corn, the latter leading to a go-ahead run by the Red Sox.
