If Lorena was to compete on the pga tour she may have a little trouble on her approach shots.
For example, the club distances of some players:

9 Iron
Mickelson: 150 yards
Harrington 148 yards
Ogilvy: 145 yards
Furyk: 140 yards
Wie: 140 yards
Ochoa 126 yards

7 Iron
Mickelson 175 yards
Harrington 175 yards
Ogilvy 170 yards
Furyk 170 yards
Wie 165 yards
Ochoa 149 yards.

Lorena hits her 5 iron about 170 yards, so she would be using that while many pga players could take a 7 iron from the same distance. Add to that Lorena would probably not drive it as far, so how many clubs more would she be taking?
