In this week’s Tour Mash, we’ll peek at a rebirth, a dominant month, and a second chance. A week ago, I wrote in this column that Rory McIlroy and Jason Day might have surpassed Jordan Spieth as U.S. Open favorites — it seems the defending champ at Oakmont might have taken umbrage at that insinuation.

Spieth’s Late Fireworks Seal Win at Dean & Deluca

Forget the “a guy like Harris English has to wonder…” intro. This story is about Jordan Spieth and the possibility that he put the Augusta crumple beyond the rear-view mirror. Spieth did what great champions expect to do: He corrected his flaws, suffered through the trials, shot 130 on the weekend and separated enough from a guy (English) who also shot 130 over the final two days to win by three strokes at the Colonial Country Club.

What, precisely, was that? On hole No. 16, the champion birdied from 20 feet. On 17, he chipped in from a killer situation over the back of the green. On 18, he staked an iron to 35 feet, then drained the snake for a third consecutive birdie and a reminder that, like The Highwayman, he is still around. One stroke back of Harris English was Ryan Palmer, at 13-under par.

Rocco Mediate Claims First Senior Major at Senior PGA

If the gods of golf were merciful, there would be a note on the coffee-room bulletin board that golfing casualties of Tiger Woods were guaranteed a senior major title. On Sunday, Rocco Mediate claimed his, at the Senior PGA in Michigan. Mediate’s Thursday 62 gave notice that he planned to matter this week, despite the presence of a particular German golfer. Bernhard Langer was in the hunt for the only senior major title that has eluded him, and a Friday 64 certainly had the competition worried. Langer would finish in third place, six back of the winner.

Colin Montgomerie, who certainly fits into the “golfing casualties of Tiger” club, gave chase, but could not catch Mediate, who followed his tournament record with 66-71-66 to win by three. John DalCorobbo, assistant pro at Brickyard Crossing (site of Sunday’s Indy 500), gave the club pros a lift with his T7 finish, 8 shots back of Rocco Mediate.

Ariya Jutanugarn On Winner’s Podium Yet Again at LPGA Volvik

If you’re asking us (and yourself), what does Ariya Jutanugarn have to do to lead off the Tour Mash, we’re not certain. Win a major championship? The young Thai professional won for the third consecutive week on the LPGA Tour, making people forget how to spell “Ko” if only for a time. This victory, unlike her previous two, was dominant: five strokes over runner-up Christina Kim.

Jutanugarn survived a rough patch of missed greens, got some lucky bounces and pulled approaches midway through Round 4. She made putt after putt from all lengths and angles, laying claim to the month of May as her own. Despite the third straight win, Jutanugarn barely entered the World Rankings top 10. Hard to imagine there are that many golfers playing better right now than she.

Chris Wood Survives for Win at BMW PGA Championship

Chris Wood can be forgiven for thinking “How did I get here?,” with here being the champion’s trophy of the BMW PGA Championship. He had no recent finishes inside the top 30 anywhere. Masters winner Danny Willett had taken charge on Friday, only to give it all back on Saturday with 76, then faltered again on Sunday with a double and two bogies, finishing in third, two shots out of a playoff. Rikard Karlberg of Sweden began Sunday bogey-ace, added seven birdies for 65, but 16th-hole bogey brought him one agonizing shot short of Wood.

As for the champion, he played like two separate men on Sunday. With an eagle sparking an outward 29, the race looked all but won, until he turned for home and ran into a wall of wind. Four bogeys on the inward half nearly derailed the train, but Wood found a way to par the last and escape with a third European Tour win.

Trainer and McCarthy Emerge at Maztlan and Freedom 55 Opens

Martin Trainer made six birdies for an outward 31, added a few more on the back nine at Mexico’s Estrella del Mar, and won by a single stroke over Argentina’s Leandro Morelli on PGA Tour Latinamerica. The victory vaulted the American into the fourth spot on the revolving door that is Los Cinco, the season-long Order of Merit competition that guarantees Web.Com Tour cards to the top five.

Dan McCarthy birdied the 18th after Tyler McCumber had bogeyed the 16th, to sneak away from the Point Grey Club in Vancouver with a Mackenzie PGA Tour Canada victory. The two-shot swing reversed each man’s fortune, with one stroke separating them in the end. Talor Gooch and Wade Binfeld made it an all-USA top four by sharing third at 13-under, two strokes out of a playoff.
