I'm this scenario your partner feels weak, like prey running from predators. The problem is your opponents don't fear him, so they don't respect him. You must change that.
Tell your partner to strike every ball he gets with the intention of hitting the opponents in the soft spots of their bodies. This experience or fear of physical pain will quickly and involuntarily, in your opponents minds, associate your partner with a feral beast that must be approached carefully, disrupting their flow and getting you out of the fridge and back in the game.
If available at your club, for a snack between the sets, your partner should partly consume a raw fish or a small mammal, (alternatively a hot dog) by biting through the skin into the juiciest part of the animal, so that some viscera is deposited on his chin and a reddish hue affected on his teeth. The prey should be abandoned after 2-3 bites to avoid satiation.
This will both reinforce the image of an apex predator and fill your partner with the primal energy to dominate the cowed opponents.
This is the only correct answer
Omg I’m dying “alternatively, a hot dog” 😂😂😂
