Yasiel Puig hit his first postseason homer at the MLB level, but he wasn't convinced it was his first

The Dodgers beat the Cubs, 5-2, in Game 1 of the National league Championship Series presented by Camping World on Saturday to take a 1-0 lead in the best-of-seven series. The win came courtesy of some quality relief pitching and some timely hitting -- and most of that came from Yasiel Puig.
The outfielder was at his absolute best in the game, swatting an RBI double to put the Dodgers on the board in the fifth inning and hitting a solo homer two innings later -- which he admired:

It was his first career postseason homer, though after the game he was surprised with that news when given to him by MLB Network's Sam Ryan. As seen atop this post, in fact, Puig was convinced he'd hit another postseason homer a few years back. 
It's worth pointing out, though, that Puig does have a pair of career postseason homers -- they came in the Cuban Serie Nacional in the 2010-11 season, prior to becoming a member of the Dodgers. 
So, then, Puig was right ... if that's what he was referring to. We'll give him the benefit of the doubt, but it definitely made for an entertaining postgame moment. 
See what Puig and the Dodgers have in store for an encore in to NLCS Game 2 on Sunday, 7:30 p.m. ET/6:30 CT on TBS.
