Hopefully ESPN will show it on TV, they showed the last 2 sets of Querrey/vasek all the way out on court 17, so I would assume that on court 1 they would also want to show Querrey. Though if Milos starts to gain control of Querrey they might not want to chow Querrey losing, but ESPN does seem to have a soft spot for Milos too
TSN was going to show Milos' first match on TSN2 while still showing the ESPN coverage on TSN, but when the match got moved to a non-TV court, they had to dump that plan. Hopefully they will do this again, but they may not since a significant part of his match is likely to be shown during the ESPN coverage.
They have also been streaming a couple courts on TSN.ca, including court 1, so I would expect them to have that going tomorrow as well.
