Over the past few weeks, we’ve heard – particularly from certain announcers or commentators – about how great Jordan Spieth is from 15-25 feet. And the statistic is true: Jordan has ranked very highly (often #1, currently #2) in that stat on the PGA Tour. It’s right here if you want to have a look: http://www.pgatour.com/stats/stat.02328.2015.html .
But… we rank 15-25 feet as an SV① skill. We say that there is almost no separation to be had in this area. Yet… Jordan Spieth has had a pretty great year, that’s undeniable. And he’s been one of the leaders in the 15-25′ category all year too, so… maybe we missed something? Maybe there’s something to this?
Let’s take a look.
Let’s first look at the statistic itself. Jordan has made 49 of 183 attempts. That’s a 26.78% conversion rate. #50 on the list is Harris English with a “paltry” 17.80%. He’s made 42 of 236. Kyle Reifers is T100 and has made 38 of 236 (16.70%). 10% sounds like a lot, doesn’t it?
Heck, if #100 Reifers converted his 236 attempts at Jordan’s rate, he’d make an extra 25 putts (236*0.2678 = 63). If #5 English converted at Jordan’s rate, he’d make an extra 21 putts. That sounds like a lot! But… consider this. Harris English has played 85 rounds, and Kyle Reifers 86. That means each would gain only about 1/4 of a stroke per round – or one stroke per tournament (or half a stroke when they miss the cut) – if they putted as well as Jordan Spieth putted. That doesn’t sound like very much.
When looking at statistics, it’s important to do some basic analysis. This is the type of analysis that the commentators seem to be hoping you don’t do. They’re hoping you don’t expose how silly their stats are. They just want to sound smart, when even a little bit of research begins to punch holes in the theory.
We’ve plotted the ranking of players ranked 1-30 in the “15-25′ Putting” category against their ranking in two other categories. First, their scoring average:
Hmmm. How about their position on the money list:
No good? Okay, surely the guys who putt well from 15-25 feet are at least some of the best putters on the PGA Tour, right? Let’s take a look at their Strokes Gained Putting:
Hmmmm.

Is this all there is to it? No. Rankings are not the absolute best way of measuring ability. After all, there was about a 10-percentage-point drop-off from #2 to #50, but only about 1% from #50 to #100. Also, though we’ve included the R2 values here, the inclusion of only the top 30 in the 15-25′ putting rank skews this slightly. Even still, the data is telling.
It just takes a tiny bit more than a quick glance to notice one guy who is having a great year being at the top. Jordan is a good player only a little bit because of his 15-25′ putting… and a lot more because of his other skills.
Yes, very much agree. I would also add that putting great from 15-25′ has an element of randomness. By this I mean that a player can finish first one year and then finish 115th the next. It is not a sign of a good putter or a way to lower your own score at all.
This tweet talks about 20-25 feet… and is probably even worse at properly representing the facts: https://twitter.com/LowScoreWins/status/625022794338844672 .
” and a lot more because of his other skills.”
It would be interesting to see how he ranks in the SV4
skills.
While sinking 15-25′ is a low SV skill, where does three putt avoidance from this distance rank as a skill? http://www.pgatour.com/stats/stat.426.html
There is clearly a very high correlation between strokes gained and three putt avoidance. http://www.pgatour.com/stats/stat.02564.html
The SV isn’t in making the 15-25′, it is putting well enough so that you will make the next one.
@cutiger2001, yes, it’s important to avoid three-putts, but people generally don’t three-putt from 15-25′. That’s why 3-15′ and 25+’ putts are more important – they have a higher Separation Value – than 15-25′ putts. From 3-15′ you have a good chance to make the putt, and from 25+’ your goal is to avoid three-putting by leaving a relatively easy, short second putt. From 15-25′ all types of golfers pretty much two-putt.
