Old school, meet new school. On-field celebrations in baseball have become commonplace, mostly in the form of home plate scrums around a guy who has just scored the winning run. It’s gone from unheard of to accepted with the span of just a few years, and, Kendrys Morales aside, nobody has much of a problem with it.

The primary factor in this recent acceptance is that it’s celebration of a victory. (Such a display mid-game would be taken very differently.) It’s also why the one position that can get away with comparable shenanigans is a closer, following the final out of a win. Think Dennis Eckersley’s six-shooters, or Brian Wilson’s crossed-arm salute.

In that regard, Cleveland closer Chris Perez isn’t so unique, freely exuberating on the mound following a job well done.

Well, he did his job on Thursday, and Alex Rios didn’t appreciate it. Perhaps it was because Rios had just made the final out of the game, grounding to shortstop Asdrubal Cabrera to close Cleveland’s 7-5 victory over the White Sox. Perhaps it was because Perez was not just gesticulating, but yelling in celebration. Maybe it was because the pitcher had also snuck in a self-congratulatory fist pump after striking out A.J. Pierzynski a batter earlier.

No matter, Rios barked at Perez as he returned to the Chicago dugout in a clear display of displeasure and frustration. (Watch it here.)

“Well, I don’t know what was wrong with [Perez],” said Rios after the game, in an MLB.com report. “He just started yelling for no reason. I don’t know why he started yelling, and that’s it. When I hit that ground ball, he was yelling when [Cabrera] was throwing to first. He was yelling the whole way. I couldn’t tell what he was saying. He was just staring and saying something.”

Because Perez does this kind of thing frequently, it’s unlikely that his comments were directed toward Rios or the White Sox. According to Rios, that hardly matters. “If he was celebrating, that was not the right way to do it,” he said.

Which is what makes this juncture in baseball history so interesting. A generation ago, Rios’ sentiment would have been gospel. Eckersley and a few rogue pitchers aside, players generally had better control of their celebratory quirks. Today, with enforcers like Nolan Ryan—who would voice his displeasure through any number of fastballs thrown at an opponent who had just shown him up—increasingly rare, acts like Perez’s are common.

It’s the game as we now know it. Seems like it’d behoove Alex Rios to come to grips with it.
