For an older junior player just getting started the Nitro 27 Prestrung Tennis Racquet is a solid choice. The racquet comes pre-strung and features a 16x19 string pattern to help generate spin and a forgiving 100 square inch head. At only 9.7 ounces unstrung, the Nitro 27 is a very mobile option for a beginner who is still developing their strokes.
