Here's a fun fact: Matt Carpenter is 0-for-16 in 21 plate appearances against one of the groomsmen from his wedding, and in Game 3 of the NLDS against the Cubs on Monday, the Cardinals third baseman will have his 22nd attempt to record a hit. But considering that groomsman is Jake Arrieta … let's just say good luck, Matt.

Indeed, Carpenter and Arrieta have been friends for years, since their days at Texas Christian University together. You'd think Arrieta, who Carpenter calls "the most flexible human being ever," would let his friend get at least one hit against him, as a belated wedding present or something, but nope.

The pair are competitive in everything, wedding party or not, and that's only magnified in the postseason. "We're going to have to toe it up against each other," Carpenter said.

But we all know who won the sunflower seed eating contests.
