Earlier on Monday, the Montreal Expos were trending on social media. However, baseball fans were left rather puzzled as the team relocated to Washington in 2004 and changed its name to the Washington Nationals.The Montreal Expos were trending because the MLB app began sending notifications to fans, updating them with scores from over 40 years ago.Some believe that the app suffered a glitch while updating team scores. Meanwhile, others jokingly suggested that the team might make a return to the MLB in the near future.Talkin’ Baseball@TalkinBaseball_MLB app casually blowing up people’s phones with scores from over 40 years ago(h/t @baseballcontext)235794MLB app casually blowing up people’s phones with scores from over 40 years ago(h/t @baseballcontext) https://t.co/egWQ4HzCj9Confused fans began tweeting screenshots of Montreal Expos alerts from the MLB app. Here are some fan reactions to the same:JonnyMacofSC@JonnyMacof@BenAndWoods Are you guys and other Padres fans getting weird alerts from the MLB app on your phone too?
