Pittsburgh Pirates second baseman Rodolfo Castro made headlines during his major league return, just not in the way he would have hoped.As the Pirates went down against the Arizona Diamondbacks on Wednesday, so did Castro’s cell phone during the 6-4 loss. When Castro slid headfirst into third in the fourth inning, his phone slid out of his back pocket.MLB rules prohibit carrying electronic devices to the field of play. If the governing body decides to dot their i’s and cross their t’s and set an example for other players, Castro could face sanctions.Ken Rosenthal@Ken_RosenthalThe Pirates’ Rodolfo Castro, who had a cell phone fall out of his back pocket last night, technically was in violation of MLB’s regulation prohibiting electronic devices on the field or in the dugout (except for MLB-approved iPads). Not known if he will face discipline.3290312The Pirates’ Rodolfo Castro, who had a cell phone fall out of his back pocket last night, technically was in violation of MLB’s regulation prohibiting electronic devices on the field or in the dugout (except for MLB-approved iPads).

Castro didn’t immediately realize what had happened.Bally Sports Arizona@BALLYSPORTSAZThis is a first... Rodolfo Castro's phone fell out of his pocket in the middle of the game 5744787This is a first... Rodolfo Castro's phone fell out of his pocket in the middle of the game 😅 https://t.co/qaPd34qroFThird base umpire Adam Hamari spotted the phone and pointed it out to Castro. He was shocked, as you would expect him to be, and immediately handed over the phone to third base coach Mike Rabelo.David Ayers@dayers63@Ken_Rosenthal The look on the face of the Pirates 3rd base coach when the player handed him the phone (while the ump is laughing) was priceless…and hilarious.@Ken_Rosenthal The look on the face of the Pirates 3rd base coach when the player handed him the phone (while the ump is laughing) was priceless…and hilarious.Speaking after the game, Castro said the following:“My first day back, if I was to be the center of attention, I would want it to be helping the team win, but never in this form. This is definitely something that was an accident, a mistake, something I’m going to learn from. But definitely something I didn’t mean to happen.”Now the talking point among MLB fans is whether or not Castro deserves disciplinary action. He claims it was a mistake. Some fans see it that way and are sympathetic toward him.Ranting New York Sports@nysportsrants02@Ken_Rosenthal LMAOOOO that’ll be such a soft move if they discipline him20@Ken_Rosenthal LMAOOOO that’ll be such a soft move if they discipline him🥤@Ic3yHurts@Ken_Rosenthal let him be37@Ken_Rosenthal let him beDillion Harper@dillionharper1@Ken_Rosenthal It’s really not a big deal lol he probably was looking at something and put it in his back pocket for a min and forgot he had it1@Ken_Rosenthal It’s really not a big deal lol he probably was looking at something and put it in his back pocket for a min and forgot he had itOthers, however, are strict advocates for legislative enforcement. Well, rules exist for a reason after all. Hence, the Pittsburgh Pirates will be under some pressure to maintain the sanctity of the law.David Janicki@DMJanicki34@Ken_Rosenthal Why would he not?

It’s just one of those things we move fowrard from and tell him, ‘You can’t do that.’”The Pittsburgh Pirates are likely to sanction Castro in some capacity. If they don’t, the MLB might intervene. A suspension seems unlikely, but a monetary fine to enforce the rule may help other players bear this incident in mind.
