Can 'bloodhound' Jordan Spieth 'sniff out' career grand slam at US PGA?

( CNN) When Jordan Spieth romped to the Masters title as a 21 -year-old in 2015, Sports Illustrated’s covering screamed, “The Spieth era begins now.”

When Spieth added the US Open title two months later — the youngest win since the great amateur Bobby Jones in 1923 — it looked like a solid forecast.

Now, ahead of his second shot at clinching the career grand slam of all four major titles at this week’s US PGA at Bellerive, it seems the headline was both sort of right and sort of wrong.

Right, in the sense that having simply turned 25, the US PGA title this week would construct him the second youngest player after Woods — and only the sixth in history — to achieve the feat. And if not this year, he will have plenty of other chances and could amass more major titles along the way.

“This tournament will always be circled until hopefully I win it one day, ” Spieth told reporters at Bellerive. “It’s a lifelong goal.”

Wrong, in that an “era” arguably indicates a period of dominance, and despite the plaudits for his play and demeanor during that breakthrough Masters win — fellow Texan and two-time Masters champion Ben Crenshaw said Spieth was “way mature beyond his years” — the Woods-esque domination hasn’t quite yet resulted.

Spieth’s stellar 2015 — he was also one shot out of a playoff for the British Open, finished second at the US PGA, became world No. 1 for the first time and won the season-long Fed Ex Cup crown — did indeed suggest the dawning of a once-in-a-generation golfer.
