If Ebden was a pure sportsman who holds sportsmanship in the highest regard, he wouldn't have complained to the umpire because he knew he wasn't gonna make it anyway. Even if the umpire called hindrance, Ebden would have said "No. It's fine. I couldn't make the shot anyway"....
Who does that? It sounds like a noble attitude, but this sport is about winning, not giving the other guy a point he screwed up all by himself.
If you are in a position to make a play, no matter if your chances are high or low to actually win the point, you're not gonna give it away like that.
Ebden did what he had to do, he ran to the ball and took the present that Fish gave to him.. and one thing that everybody knows who plays and/ or watches tennis - you accept any present your opponent gives to you (:
Doesn't have to to anything with bad sportsmanship imo
