SEATTLE (AP) Coming off a marquee win to open the season, Washington spent the first 20 minutes looking unenthusiastic and sluggish.

What was expected to be an easy home opener before another big weekend showdown turned into a bigger fight than the Huskies expected.

Isaiah Stewart scored 16 points and blocked five shots, Nahziah Carter scored 12 of his 14 points in the second half, and No. 20 Washington overcame an awful first half offensively to pull away for a 56-46 win over Mount St. Mary's on Tuesday night.
