Mannerino’s string tension at Wimbledon

Listening to the commentary at Wimbledon qualifiers the other day and the stringers room came up. The lowest tension was for Mannerino at 13.8kg or 31.42 pounds. Wow! That’s in an Apd, not some control racquet like an aero vs, but the apparently wild Apd. Pretty sure he is still using Alu power strings. That’ pretty cool, I thought. the other thing mentioned was the average tension for players has come down from around 54 to 50 pounds over the last few years.
