Madison Bumgarner Ejected After Hand Check For Sticky Stuff

Major League Baseball has continued checking pitchers for "sticky stuff" this season, though there hasn't been as much drama with the checks so far this year. We got our first blow-up on Wednesday, though, as Madison Bumgarner was thrown out following a post-inning confrontation with an umpire.
The Arizona Diamondbacks are facing the Miami Marlins today and after the bottom of the first inning, Bumgarner had his pitching hand checked by first base umpire Dan Bellino. The check took a bit longer than usual and appeared to get contentious. Then Bumgarner said something that got him ejected.

And here's another look, where you can see Bumgarner say something that gets him tossed:
It appears Bumgarner was ejected for something that was said, and not for what was on his hand. pic.twitter.com/g7TldjHHLs

I'm speculating here but it looks like Bumgarner appeared annoyed that the check was taking so long so maybe he said something related to that.
