My St. Louis-living brother, who is actually in Berlin now, informed that because the match ran long, the channel in St. Louis showing it ran into a problem because it also had to show the Cubs-Cardinals game, starting at 2:15 pm Central Time.
So, what did the station, KSDK, do? They went to a split screen and showed baseball and tennis simultaneously. This turned out not to be very popular with fans of either tennis, baseball, or human beings with binocular vision. You can find an image of what the screen looked in this link from the St. Louis Post-Dispatch.
Also, without looking it up, what do you think was the total difference in points won between Nadal and Federer for the match?
