Yesterday we hinted in this column at the potential for low scores on the Olympic course in Rio. On Day 1, we saw a 63 and a bucket of 66s and 67s. Day 2 brought a 65 and 66 as the two low scores. However, a quick look at the metrics of each hole reveals how the course can be had, and how one of those recent Tour 58s (or something near it) is within reach.

Let’s begin five things we learned on Day 2 with a look at those important numbers.

Half the holes in Rio are playing under par

All four par-5 holes can be called birdie holes, but golfers aren’t likely to make eagle. The long holes have yielded 88 birdies but 0 eagles. The four eagles have been counted on two par-4 holes (Nos. 3 and 16) and Justin Rose’s 1st-round ace. Interestingly, three of the five short holes are averaging below three strokes per hole, rare for par-3’s. As for the two-shot holes, Nos. 9 and 16 are victims of Olympian expertise.

If someone gets hot and takes advantage of those nine holes, he could be off to the start needed to go super-low. This is important, because Days 1 and 2 have also revealed…

Rio’s Trio can ruin your day mid-round

The 11th, 12th and 13th holes are all playing at least one-quarter shot above par. That’s quite a stretch. The holes have been responsible for 51 bogeys and 7 doubles, plus one other (the bad type.) Ten birdies have been scored on the holes, so they aren’t impenetrable. If that same someone from No. 5 could navigate Rio’s Trio at par or better, watch out.

At the same time, if a leader stumbles just past the turn, those in pursuit have renewed hope.

Team USA began to dig itself out of its first-round hole

Matt Kuchar shot under par again, but not low enough to make a move up the board higher than a tie for 14th. Bubba Watson was good for 67, moving into 18th place. Patrick Reed was also under par, coming in at 22nd at the halfway post.

As for Rickie Fowler, well, he shot par and hung out with Matthew McConaughey. Fowler won’t win a medal, but his circle of acquaintances might be worth something to those who care about trendy dudes.

The Olympic men’s golf competition is an international affair

The first 14 golfers belong to 14 different countries. You have to count down to Emiliano Grillo (Argentina) and Nicolas Colsaerts (Belgium) at a tie for 14th to have your first country repeat. It’s probable that the organizers and proponents of the competition were hoping to increase the popularity of the game throughout the world. The sight of Chinese Taipei and Norway in the top-10 suggest that baby steps are being taken.

My halfway pick to wear the golf medal is…

Thomas Pieters. Not a real reach, as the Belgian sits one back of Marcus Fraser (10-under), who maintained his tenuous lead with a 69 on Friday. Pieters has the talent to win the big one, and the Olympics would certainly qualify as one of those. Despite the presence of Open champion Henrik Stenson at 8-under and Justin Rose at 6-under, we like Pieters to break through on the Olympic stage of Rio 2016. The University of Illinois graduate had seven birdies in his day-low round and looks to be on solid, spectacular form.
