On Saturday evening against the Minnesota Twins, Danny Duffy came out of the Royals bullpen with two outs in the seventh inning.
Starter Ian Kennedy had finished up his night, and Duffy was called on to get the last out. There were runners on first and third at the time.
The Royals were up 7-0, so when Eduardo Escobar, the runner on first, took off for second, the Royals ignored him.
But catcher Salvador Perez immediately paid a visit to the pitcher's mound.
The first time a pitcher gets a runner on second base, don’t be surprised if you see the catcher go out to the mound.
