Preliminary Data on String at ITF Pro Circuit Wake Forest Futures

The final numbers won’t be in for a while, but I was organizing my string reels for the ITF Pro Circuit Wake Forest Futures at Wake Forest University (USA F17) and thought I would provide this preliminary string check photo.

Stringing Report for 2016 Pro Circuit $25K Futures of Winston-Salem

At the 2015 ITF Pro Circuit $15K Futures of Winston-Salem last year, I strung rackets for 34 different players. The number increased to 47 different players in the 2016 tournament (out of 83 unique players in the singles and doubles). The total number of rackets I did for the tournament also increased from 112 in 2015 to 139 in 2016.

So, the additional $10K in prize money seemed to make some difference in players’ willingness to pay for on-site stringing (although I heard the numbers for this year’s Tulsa $25K the week following Winston-Salem were lower than the 2015 Winston-Salem Futures).

Last year the top stringer was the tournament champion, Matija Pecotic, with 15 rackets. This year’s champion, Sekou Bangoura, only strung 7 rackets.

Top stringers this year were three players tied with 8 rackets each: Jon Ho and Dennis Uspensky, both Wake Forest players who I have tried to teach the importance of racket stringing, and Emil Reinberg of the University of Georgia, who fought his way through qualifying and won two rounds in the main draw for 5 total matches.

Like last year, almost all players (42 of 47) used all monofilament strings, including two who used hybrids of two different monofilaments. Two players used a traditional hybrid of monofilament mains and synthetic gut/multifilament crosses, and one player used natural gut mains and monofilament crosses (something we see much more commonly on the ATP World Tour).

Winston-Salem Futures String Check

As with last year, the three most common string brands were Solinco, Luxilon, and Babolat. Interestingly, their “market shares” were almost exactly the same this year (last year’s share in parentheses):

  1. Solinco – 38% (38%)
  2. Luxilon – 22% (21%)
  3. Babolat – 10% (12%)
  4. Wilson –5.3%
  5. Pacific, Diadem – 4% (6% each)
  6. Tecnifibre – 3% (3%)
  7. MSV, Kirschbaum, L-Tec, Prince – 2%

(Note that 2% = 1 racket)

Stringing Report from 2015 NCAA Division 1 Tennis Championships

As noted previously (here and here), I recently spent 2 weeks as one of the official on-site stringers for the NCAA tennis tournament at Baylor University in Waco, Texas. Although we had some competition from off-site stringers who aggressively solicited business away from us, the four members of the MOZI Tennis team still strung several hundred rackets. This included the women’s doubles champions from Alabama, and the men’s singles, women’s singles, and men’s doubles finalists (from Wake Forest, Stanford, and Texas).

I personally worked on rackets for 49 different players from 27 teams. This included 18 women from 12 teams and 31 men from 15 teams. Although this is not a random sample of all players in the tournament, it is a fairly diverse group of players.

For these 49 rackets, the string tensions I observed were:

  • Overall: 43 pounds to 63 pounds
  • Men: 43 pounds to 59 pounds
  • Women: 46 pounds to 63 pounds
  • Overall average: 53.3 pounds
  • Men’s average: 52.25 pounds
  • Women’s average: 55.2 pounds

I find it interesting that even though men can generate more power on their own than women, women tend to string tighter than men. Part of this may be due to women generally using more open string patterns than men, but it is also the case that each player develops their own feeling for the optimal string tension for their particular racket and game. To wit: the highest recorded tension in our stringing room was 69 pound mains and 68 pound crosses.

Head Speed with RPM

Almost all of the players, men and women, used all polyester monofilament strings – 44 of 49 players. 4 players used hybrid stringing (monofilament mains and synthetic gut/multifilament crosses), and 1 player used all multifilament string.

A few string brands were most common:

  1. Luxilon – 31%
  2. Solinco – 20%
  3. Babolat – 16%
  4. Pacific – 12%
  5. Wilson – 6%
  6. Prince, Tecnifibre – 4%
  7. Head, Kirschbaum, Pros Pro – 2%

Pacific was overrepresented because I strung all of the rackets for Wake Forest men’s tennis team which has an agreement with Pacific.

NCAA Rackets

Racket brands are even more concentrated than string brands:

  1. Babolat – 41%
  2. Wilson – 29%
  3. Head – 24%
  4. Dunlop, Prince, Tecnifibre – 2%

An amazing 94% of players used one of three brands.
