Nolan Arenado is the least-popular man in New York City today. The St. Louis Cardinals third baseman traveled to Citi Field yesterday to take on the New York Mets in a four-game series. The teams were supposed to lock horns starting last night, but New York's unpredictable weather struck and postponed the matchup, setting up a Tuesday doubleheader.All the better for New York Mets fans. Today, they were treated to a single-admission doubleheader against their most-hated rivals so far this season. When the Mets traveled to St. Louis, Missouri, back in late April, a bench-clearing brawl broke out. And guess who started it? Nolan Arenado did. Mets pitcher Yoan Lopez ran a fastball up and in on Arenado. It didn't even hit him. But based on the game's circumstances and mounting animosity between the two clubs, Arenado took exception. He yelled at Lopez before trying to charge the mound. And then everybody got involved, including fans on Twitter.New York Mets fans hate Nolan Arenado and are making it clear on TwitterSt. Louis Cardinals third baseman Arenado started a bench-clearing brawl against the Mets on April 27.When the first game of today's doubleheader kicked off, Mets fans were ready. They booed Nolan Arenado as soon as he made his first appearance on the field, which was for the game's third at-bat. Here's how they reacted on Twitter.This Mets fan wishes the oddsmakers had given an over/under on the likelihood of Arenado "acting like a toddler" today. There's a statistic you won't find on the scoresheets or even Baseball Savant.Chris Polansky@ChrisKPolanskyFour-game Mets-Cards series kicks off today.

That's what this user did, and they didn't hold back. The best part? They were replying to a highly-respected Mets beat writer, Anthony DiComo.TheRealZion@TheRealZion93@AnthonyDiComo Nolan Arenado is a bitch1@AnthonyDiComo Nolan Arenado is a bitch"Nolan Arenado is a b***h" - @ TheRealZionThis user wants the Mets to show Arenado and his team "who's boss." The Mets are 5-5 in their last 10 games. These fans are hoping they'll win more than 50% of this series' games.Stephanie Lynn@x0stephhhOkay boys let’s show that baby Nolan Arenado & the Cardinals who’s boss!!!! #LFGM 🧡264Okay boys let’s show that baby Nolan Arenado & the Cardinals who’s boss!!!! #LFGM 💙🧡"Okay boys let’s show that baby Nolan Arenado & the Cardinals who’s boss!!!" - @ Stephanie LynnHere's a New York Yankees fan who doesn't like Arenado either. They found it laughable that another user believed Arenado to be better than Aaron Judge.Dalton@DaltonJElwoodThere’s simply no shot we’re using just over a 30 game sample to say “Nolan Arenado” is better than Aaron Judge 🤣🤣🤣 twitter.com/vollner_xiii/s…Wavy Patty@vollner_xiii@DaltonJElwood .312/.374/.600 8 29 w a top 3 glove in ball.296/.369/.632 12 27 w a solid glovewhen the numbers are that close & the glove is that big of a disparity then yes, easily1@DaltonJElwood .312/.374/.600 8 29 w a top 3 glove in ball.296/.369/.632 12 27 w a solid glovewhen the numbers are that close & the glove is that big of a disparity then yes, easilyThere’s simply no shot we’re using just over a 30 game sample to say “Nolan Arenado” is better than Aaron Judge 🤣🤣🤣 twitter.com/vollner_xiii/s…"There’s simply no shot we’re using just over a 30 game sample to say Arenado is better than Aaron Judge" - @ DaltonDiscrediting all of Arenado's production this season must be in style. Here's another user who flatly denies that the Cardinals slugger is a "star." He's batting .312 with eight home runs this season. We'll just leave that there.Cody Pirkl@CodyPirkl@Tredidy_19 Is Nolan Arenado a star? He must not be, because Polanco hit better than him last season.@Tredidy_19 Is Nolan Arenado a star?

We're sure Colorado Rockies fans agree.Ursula@urslovesthemetsNolan Arenado still looks completely wrong in red & white.Anyway, #LGM11Nolan Arenado still looks completely wrong in red & white.Anyway, #LGM https://t.co/rNgJ9bDo35"Arenado still looks completely wrong in red & white." - @ UrsulaThis same user followed that tweet up with another questioning the anti-Arenado movement in New York. She had no clue why all her fellow Mets fans hate the guy. Ignorance is bliss.Ursula@urslovesthemetsDid Nolan Arenado do something, or do we just hate him because he's good? People were booing him out here. #LGMDid Nolan Arenado do something, or do we just hate him because he's good?
