Dustin Johnson has now won 5.7 percent of PGA Tournaments he has played in his career after taking the Bridgestone Invitational by a stroke over Scott Piercy on Sunday. This probably doesn't sound like a big number, but let's look at some context from other players not named Tiger Woods.

  • Rory McIlroy -- 9.9 percent
  • Jordan Spieth -- 8.2 percent
  • Phil Mickelson -- 7.7 percent
  • Jason Day -- 5.4 percent
  • Bubba Watson -- 3.6 percent

Johnson is smack in the middle of these generationally-great players. McIlroy's number, by the way, is probably a bit skewed because he spent the first part of his career growing up in Europe while these other players were grinding away on the PGA Tour but often not winning. McIlroy was more seasoned when he started his PGA Tour career.

Either way, Johnson is filling out that presumed resume his talent always said was coming -- a major, a third WGC title, an 11th PGA Tour crown and just his second season overall with multiple wins.

"It definitely gives me a lot of confidence, and maybe free me up, too," said Johnson on Sunday in a statement that should frighten the rest of the PGA Tour. "I don't know, I'm definitely a little more relaxed out there on the golf course, especially coming down the stretch. Today, I felt I was in a really good place, really calm, collected, just focusing on what I was doing. Just playing golf."

It's hard to imagine someone like Johnson becoming more relaxed than he has been throughout his career, but that is apparently what's happening. He's better on the course, too. He has always been a prolific driver, but now he's in the top 40 in strokes gained putting and No. 1 (!) overall in proximity to the hole from 50-125 yards (see below). Those are scary numbers. It doesn't stop here for Johnson either.

"The goal is to get to that No. 1 spot," continued Johnson. "I mean, it's important. I've still got a lot of work to do to get there. It's not just getting there, you want to stay there. I'm looking forward to the challenge."

The terrifying thing for other players should not be some sort of unlocking of Johnson's mental potential. That was likely never going to change. The terrifying thing should be that he's getting better as a golfer. He's changing facets of his game with ease. Take the power fade he's now hitting off the tee.

"I've been fading it most of this year," said Johnson. "I've been drawing it pretty much my whole career on Tour ... and this year I've been fading it all year this year. I feel like I hit a lot more fairways. Maybe the stats don't say it, but I feel like I do, so I think that's the most important thing. I just don't feel like my misses are as bad."

The stats back him up. Johnson is gaining 1.12 strokes per round off the tee compared with .96 last year and .73 the year before that. Like I said, terrifying.

So now the Summer of D.J. heats up with the British Open (where he's always had at least some success) and the big park of a PGA Championship. How high can he fly as the U.S. hurtles towards the Olympics (which he qualified for) and the Ryder Cup (which he will be a part of).

"It's the first time I've won two tournaments in a row," said Johnson. "I know it wasn't like two consecutive tournaments, but consecutive tournaments that I played. I mean, that's big. I'm excited and looking forward to going over to the British with the golf game in good form."

The answer to the "what is Dustin Johnson's ceiling?" question might not be one other players want to think about.

"Dustin Johnson is arguably the most talented player on the PGA Tour," Jordan Spieth told ESPN before the U.S. Open in a sort-of foreshadowing. "I think he's not only a freak athlete but a freak golf athlete -- like, he has great hands, great club face control. I mean, he hits some shots where you won't see anybody else trying to."

The answer to this question is one we're all about to find out together.

Let's go Inside the Numbers from the Bridgestone Invitational.

9 -- The combined rank of Johnson's strokes gained off the tee (No. 1) and strokes gained putting (No. 8) for the week at Firestone. If that combined number is under 10, that's bad news for people not named Dustin Johnson.

1 -- Johnson's rank on the PGA Tour this season in proximity to hole from 50-125 yards. He's going to have preposterous seasons if this continues to be the case.

11 -- Wins for Johnson in 194 career starts on the PGA Tour. That's insanely good.

2 -- Straight tournaments Scott Piercy has finished second behind Dustin Johnson. He hasn't gotten a lot of notoriety for it, but Piercy is a D.J. suspension from possibly having two straight wins.

5 -- Times in the last six that Jason Day has converted a 54-hole lead or co-lead.
