Since I have no life I looked up the records of all qualies playing in challengers this year.
Clay 100-144 ..40%
Hard 195-292..40%
I don't think qualies on the ATP level win at a 4/10 clip.
This is through last weeks tourneys.
Also this...
Overall first round...179-252..41.5%
2nd round- 86-136 ..38.75 5
3rd round 30-44..40%
4th round 4-21..16%..(Qualies are gassed by then having played most likely 6-7 matches in 8-9 days
Finals 2-1.
I know the math does not add up exactly...but more or less you see the percentages..I did this late at night over the past few weeks..so I might have missed a few.
So whenever a qualie reaches the semis through his opponent in a parlay. usually the opponent is a big fav due to fatigue on the part of the qualie.
Lately qualies are in a HUGE slump last few weeks.Hitting about 29%...TIME to get hot???five tourneys on the docket this week.Mons,Sac town,medellin,sau Paulo and Mohammedia
