Premature String Breakage.
Framing a ball is one of the most frequent reasons for premature string breakage. This happens when the player doesn’t strike the ball in the center of the racquet and instead, hits the ball off the side of the frame. Half of the ball is on the frame and half of it is putting tremendous downward pressure on the grommet where the string enters the frame. As the stringer there’s NOTHING— repeat —NOTHING that we can do, that will prevent the strings from breaking if this happens. Even ATP Pros frame the ball occasionally, but many of them use low power, flexible tennis racquets that aren’t as stiff and as detrimental on strings. Keep in mind too, that a professional tour player will pull out a freshly strung racquet at each ball change – in other words, every 9 games. Their strings don’t see that much wear, and they certainly miss-hit less than most.
Many weekend and club players use stiffer racquets, combined with the increased popularity of polyester strings, (such as Luxilon Alu Power, Babolat RPM Blast, Head Sonic Pro or Solinco Tour Bite) increase the chances of premature string breakage. A miss-hit using natural gut in a stiffer frame will also shear a string bed – usually up towards the head of the frame between 10 and 2.
Your best option is to try lowering tensions to lessen the impact and shock. We suggest using power pads on the first 6 to 8 main strings at the throat to also reduce shock.
Your stringing professional cannot be responsible for a string breakage that occurs because of this and cannot be expected to restring your racquet at no charge when this occurs.
