Jake Arrieta

Jake Arrieta pitched nine innings Wednesday, struck out 11, gave up four hits, cleared the benches, got a player to attack a Gatorade cooler and broke the hearts of the city of Pittsburgh.

After the game, he responded to one tweet. It was about his nipples.

Well, you learn something new every day. Arrieta is fidgety on the mound, and he is one of the huskier pitchers in baseball, so this is not a complete surprise. It is a bit graphic and a unique choice of response for apparently the only tweet that mattered to Arrieta after the Cubs' 4-0 Wild Card Game win over the Pirates.

Here are the highlights from Arrieta's August no-hitter to study his mannerisms:

Arrieta sent one other tweet after the game, an hour before the nipple response, but it was a more straightforward message.

The Cubs start the NLDS in St. Louis on Friday evening. Arrieta should be projected to return to the mound Monday on four-days rest for Game 3 at Wrigley Field. The Cubs have never played the rival Cardinals in the postseason.

After seeing how Cubs players and fans celebrated the wild-card win Wednesday, what will they do if the team actually goes all the way?
