Nothing annoys me more than playing fairly high level doubles with a doubles newbie, who is constantly guarding the alley from a low percentage passing shot. When I'm in a cross court rally with the opponent going 5.. 6.. 7 balls, here's my partner doing absolutely nothing but guarding the alley They are not even executing a head fake or pretending to move into the middle to poach the ball to put pressure on the opponent. For these people, I start barking... "move in!" It's not pretty but eventually it works. I then explain that with the ball I'm hitting to the opponent (deep and spinny), it would be very low percentage to try a passing shot down the alley. If the opponent did hit that shot, I'm playing back and could probably cover it unless it was very hard, flat and accurate. If they do make it 10% of the time, then kudos to them. It's a thing of beauty when a partner finally gets into the rhythm and starts moving back and forth between the alley and center of the court during a CC rally.. waiting for the right shot to poach. Anyone else deal with this frustration?
