SAN FRANCISCO—In a statement issued after Wednesday night's Rockies-Giants contest, home plate umpire Laz Diaz warned all catchers around the league that he is "onto their little game," and is easily able to tell when they slyly move their glove into the strike zone after catching a pitch off the plate. "You catchers seem to think that I was born yesterday," the statement, which called the catchers' tactics "dishonest, immature, and tantamount to cheating," read in part. "Some of you even believe you can fool me by holding your glove there for an extra long time, as if to say, 'See, I'm holding it here like this because it was a strike.' Well, this umpire is not falling for that. Not today, not ever." Diaz further stated that a batter who removes his elbow protector, drops his bat, and begins heading to first base will never coax him into calling ball four.
