Fed breaks a 4 tie-break lost streak, which is very important before Wimbledon because tie-breaks often go by streaks and very seldom does he have such bad tie-break streaks.
His game was encouraging even though the serve was not as great as the score lets people think.
I haven't seen him play that well in Halle for several years.
Before grass season, I was less optimistic about Raonic's abilities on grass than many people : I saw today what I thought, that he's more comfortable with high balls from the baseline than with low balls.
That said his serve is impressive and in Wimbledon second week the bounce will be better for him.
Better not draw him in R16
