Brock Holt has umps check glove after slow pitches vs. Athletics. Before you read this, go crumple up a paper ball and peg it at a trash can as hard you can. Congratulations, you've probably thrown an object faster than an MLB pitcher on the mound this year. Texas Rangers third baseman Brock Holt took the mound on Saturday and came out firing with a historical dearth of heat. His first pitch: a 31 mph strike that really has to be seen to be understood. #BrockHolt #Holt #31MPH
