Jordan Spieth's hopes of winning the Grand Slam are about to be wrecked by bad weather

Winning a major -- let alone all four in the same year -- takes a certain amount of luck. Spieth's enjoyed that so far: He was undoubtedly the best player in the field at the Masters, and while he was probably was the best player at the U.S. Open, he also had to rely on Dustin Johnson missing a short putt on the final hole to hand him victory.

But it looks as that run is about to come to an end.

Spieth is a scheduled to play at 09:33 a.m local time on Thursday, which will flip to 2:34 p.m. on Friday when he starts his second round on Friday. Weather is usually the decisive factor in British Opens, and by being dealt the morning-afternoon side of the draw, Spieth has ensured he'll get the worst conditions possible.

Thursday won't be too bad, he might catch a bit of rain, but it's the Friday forecast which looks like a nightmare. Heavy rains overnight that'll soften the course up, combined with sustained 25 mph winds during the afternoon that are expected to reach up to 40 mph at points.

Jordan Spieth, generally speaking, hits the golf ball higher than the average tour pro. He ranks seventh and 11th on tour in apex height and ball hang time, respectively, so he'll find it particularly challenging to play in these conditions.

That doesn't mean he can't play well, obviously, but it means that if you're asking Spieth to win this week, you're essentially asking him to be the best player in a tournament where he hasn't done well in the past (T-44 and T-36 in his last two starts) and with the pressure of a grand slam on the line, all while navigating the toughest conditions the tournament has to offer.

It really seems a stretch too far this time, but, at the start of the season, so did the idea of a 21-year-old winning the Masters and the U.S. Open.
