Managers have less to argue about as Major League Baseball starts ball-and-strike challenges this season with so-called robot umpires.

Monday’s suspension -- and eventual firing -- of former Astros managers AJ Hinch puts him in the record books. Hinch is now one of just three baseball managers to be suspended by the MLB for a year or more. Jayson Stark, a senior baseball writer at The Athletic explained the significance of Hinch’s suspension in this tweet. And according to Baseballhall.org, Leo Durocher, manager for the Dodgers in 1947, was suspended for “accumulation of unpleasant incidents,” associated with gambling. He was a manager for 24 years, including a stint with the Astros.
