For the past couple of days, I’ve found myself wondering about just how advantageous home court advantage is in tennis.  Does it confer the same enormous weight as it does in team sports like football and basketball?

Yesterday, I finally started to look for answers. Since I found no sites online that distinguish between home and away records in tennis (and if there is one, please let me know so I can feel silly about having done all this work), I decided to do my own research on the matter. Here’s what I found:

Player Home Hard Court Win% Away Hard Court Win% Home Clay Win % Away Clay Win % Home Grass Win % Away Grass Win % Overall Home Win % Overall Away Win % % of matches played at home
Jack Sock 54.55% 50.00% 65.79% 62.50% 50.00% 33.33% 56.29% 52.94% 89.88%
Michael Russell 63.04% 56.48% 62.81% 44.04% 58.33% 42.86% 63.35% 48.75% 68.37%
Denis Kudla 56.73% 61.54% 55.56% 45.45% 42.86% 58.62% 57.29% 56.60% 78.97%
Tim Smyczek 57.27% 61.11% 59.26% 0.00% 66.67% 55.00% 57.47% 52.27% 91.63%
Ryan Harrison 58.46% 57.14% 53.85% 45.45% 55.56% 50.00% 55.88% 51.61% 68.69%
Rajeev Ram 49.50% 53.00% 35.71% 33.33% 70.00% 34.48% 52.17% 48.24% 71.99%

Wayne Odesnik 62.24% 51.28% 70.59% 58.08% N/A 50.00% 62.56% 56.36% 64.40%
Bradley Klahn 65.98% 50.00% 41.18% 50.00% 0.00% 50.00% 59.52% 50.00% 92.65%
Donald Young 58.05% 57.50% 56.00% 0.00% 40.00% 36.36% 57.07% 47.73% 81.55%
Bobby Reynolds 61.87% 56.00% 53.85% 27.27% 40.00% 53.66% 60.15% 51.38% 82.73%
Steve Johnson 58.14% 72.73% 47.06% 60.00% 50.00% 75.00% 57.03% 69.23% 83.12%
Austin Krajicek 58.09% 76.47% 65.22% 33.33% N/A N/A 60.22% 65.22% 89.00%
Brian Baker 53.70% 53.33% 87.14% 73.33% 66.67% 61.54% 64.07% 59.57% 83.09%
Robby Ginepri 58.02% 50.00% 48.15% 45.65% 69.23% 39.02% 56.99% 50.26% 66.26%
Tennys Sandgren 63.11% 40.00% 55.17% 16.67% N/A N/A 59.56% 27.27% 94.33%
Bjorn Fratangelo 46.94% N/A 63.64% 75.00% N/A N/A 57.66% 75.00% 89.54%

And yeah, I know that table is hard to read. Alas, my wordpress/HTML tabling skills aren’t what they could be.  To that end, I had to eliminate the “Indoor Home Win Percentage” and the “Indoor Away Win Percentage” columns in order to make room for the rest.  If you’re desperate for that information, I’ll be happy to email it to you.

To make things slightly more legible/enjoyable, I’ve colorfully highlighted the numbers I’m focusing on.  If you’re interested in the methodology behind how I arrived at these numbers, do please check the footnote*.

But within this horrid chart, the first thing that jumps out at me is:

Three of the four players who have a better winning percentage outside North America than they do within have something in common — can you spot it?  That’s right: they all played collegiate tennis. Rhyne Williams, Stevie Johnson and Austin Krajicek all have better records in far-flung regions than they do in the American North.

This suggests a few things.  First, the learning curve isn’t as steep transitioning to the pro game from college. This could be because a) they’re more familiar with playing against hostile crowds and people cheering against them (those of you who watch college tennis will know of what I speak); b) their bodies are more developed and physically able to keep up with the men as they begin life on the pro tour; c) their strategic sense is more developed or; d) all of the above. I lean toward “d”, myself, but I’m open to other suggestions.

(Author’s note: yes, I know Tennys Sandgren’s match record away from home flings a statistical wrench at my theory.  However, Sandgren is the American who plays the largest percentage of his matches on U.S. ground, and I don’t consider eleven matches (3 wins, 8 losses) to be a large enough sample size to be statistically relevant.  So my theory remains largely undamaged.  I think.  Maybe. You be the judge.)

You also may notice a red-highlighted Bjorn Fratangelo hangin’ a hefty 75 percent win rate in the foreign soil column.  In this case, the word “soil” is the key to figuring out that stat; e.g. the 2011 French Open Boys Champion is a red clay hound, and there ain’t hardly many red clay courts Stateside.  So he and his team have done a great job finding the proper venues through which he can find success.

The above numbers also give Ryan Harrison a couple of boosts he might be in need of these days: Harrison is the only “young gun” to play over 30% of his matches away from home. Only  the older guys like Robby Ginepri, Wayne Odesnik, and Michael Russell have played a similar schedule. Plus, Ryan has a winning record both at home and on the road.
