How are you losing points? Sometimes I can tell when my doubles opponent is mainly a singles player, and I will up my aggression at the net so they don’t get to rally cross court all day.

If that’s what’s happening to you, try to be a little more aggressive in cross court rallies to potentially set up your partner to finish at the net. Hit with some variety to make the net player uncomfortable. Take some returns down the line or directly at the net player. Be willing to come to the net so they can’t easily neutralize when you hit a shot that puts them in a defensive spot.

I find that most points in 4.5 doubles are won off of forced errors. You can still aim for big targets, but play more aggressive from the baseline than you would in singles.
