A day after mathematically being eliminated from the playoffs, the Washington Nationals went looking for a new sparring partner. And found one in each other.  After a flyout in the eighth inning, Nationals superstar Bryce Harper returned to the dugout to closer Jonathan Papelbon yelling at him from the bench.  The argument continued and the two got physical, with Papelbon lunging at Harper’s throat. After teammates pulled them apart, Papelbon went out to pitch the ninth inning.  Unfortunately, this isn’t the first (or probably the last) example of Papelbon acting out both on and off the field.  RELATED: NATIONALS BAN PAPELBON 4 GAMES  It was the grab seen ‘round the world.  After giving up four runs in the top of the ninth inning against the Miami Marlins on Sept. 14, 2014, Jonathan Papelbon left the diamon to a chorus of boos from the Philadelphia Phillies fans. In turn, he responded by not-so-subtly adjusting himself as he walked toward the dugout.  FLASHBACK: PAPLEBON SAYS HE SHOULD CLOSE ALL-STAR GAME OVER MARIANO RIVERA  Umpire Joe West ejected Papelbon for the crotch grab, after which the pitcher launched into one of his famous tirades.  “I mean this is baseball. I had to make an adjustment and I did it,” Papelbon said as way of an explanation after the game.  The closer was suspended for seven games and fined following his outburst, but that wasn’t enough to teach him a lesson in on-field etiquette.  On the next train out of town  When Jonathan Papelbon signed a four-year contract with the Phillies, they were just coming off a .630 season after losing to the St. Louis Cardinals in the National League Division Series.  But for the next three years, the Phillies cracked .500 only once. By mid-July this year, the team was 29-62 (a .319 winning percentage) and Papelbon wanted out.  “It’s not what I signed up for,” Papelbon told The Boston Globe.  “I signed up for a team winning 102 games and it didn’t happen. I’ve tried to ride that ship as much as I can. I’ve tried to keep my mouth shut as much as I can. I think three years is enough time to ride that out. If fans can’t understand that, I can’t side with them on that.”  Papelbon got his wish and was traded to the Washington Nationals on July 28, and Phillies fans were barely upset to see him go.

After allowing six of the seven batters he faced to reach base and giving up a two-run lead in his first save opportunity of 2014, Papelbon passed the blame onto anyone and everyone else.  “Obviously I don’t know whether that’s called from the bench or called from the middle infielders, but less than two outs I’m thinking ground ball and I’m thinking let’s get this double play and go home,” Papelbon told Philly.com.  Papelbon ended the day going 0.1 innings, giving up four hits, three earned runs and two walks.  Say my name, say my name  Following the success of Chad (Ochocinco) Johnson, Papelbon decided he would take a similar nickname for his alter-ego: Cinco-Ocho, for the No. 58 on the back of his jersey.  Over the years, Cinco-Ocho came out to play in press conferences and interviews.  On why he insisted on an extra $58 for his Phillies contract, he responded: “You’ll have to ask Cinco Ocho that question. I can give you his phone number if you need it.”  On getting the No. 58 from Phillies left-hander Antonio Bastardo: “Basically, I told my agents to tell Bastardo to give me the number or Cinco Ocho was going to kill him.”  On needing extra motivation in his first game against the Boston Red Sox: “I don’t need extra motivation. You should know that by now. Cinco always has the advantage. Whatever he does. He doesn’t know how he do, he just do. Never under-estimate Cinco-Ocho. It’s 10-1 odds, don’t ever bet against him.”  After roaring onto the baseball scene with a .443 batting average in the first 27 games of his MLB career, Los Angeles Dodgers outfielder Yasiel Puig garnered massive fan support in a write-in vote for the 2013 All-Star Game.  Papelbon, however, didn’t think Puig deserved to play in the Midsummer Classic, saying it would be “a joke” and an “injustice” to veteran players.  “This Yasiel Pig, or Puig, or whatever,” Papelbon said in a radio interview on Sirius XM.  In 2006, Papelbon was voted onto the All-Star team in his rookie season.  In a 2009 Deadspin article, Alan Siegel, a former sportswriter for The Eagle-Tribune in Lawrence, Massachusetts, said that Papelbon enjoyed watching porn in the Red Sex clubhouse; “Squirts Illustrated,” the day Siegel walked by.  In a 162-game season, the clubhouse becomes more like home for many players, but some things just don’t need to be seen in public.
