Ricky Rubio, who grew up in Spain and turned pro as a teen, never got to play in the NCAA men’s basketball tournament, nor does he have an American alma mater to root for. But through one day of action, he managed something that may be even harder than winning a national title: a perfect bracket.

The run ended early in Friday’s slate of games when Syracuse upset Dayton.

Rubio first tweeted about his bracket Thursday. That drew some doubters, so he offered a photo while the late game was still in progress:

There’s a lot of tournament left, of course, and with another slate of games already underway, Rubio’s run could be over by the time you read this. But nailing the first 16 games is no small feat: According to ESPN, just one-tenth of 1 percent of the 13 million brackets submitted to the network’s tournament contest remained flawless after the first day.

Rubio’s affinity for underdogs paid off: He picked two No. 9 seeds, two No. 11s and two No. 12s to advance Thursday, while his Friday picks lean more on favorites.

The odds of going the distance with a perfect bracket are estimated at somewhere between 1 in 128 billion and 1 in 9.2 quintillion.
