He'll win the long rallies. I see a ery respectable 1st serve % for Raonic, 65 % today he (only) made 7 aces though, compared with his normally double figures. However he was never in trouble so didn have to pull the trigger.
I meant that Milos could struggle in the long rallies.
Especially if Andy can play with variety, changing up the pace and moving Milos about a lot. Should be an interesting match to watch though - one of the best servers against one of the best returners, good contrast of styles.
