Zack Greinke lasted just two batters before being ejected by first-base umpire Sam Holbrook against the Astros on Saturday afternoon. Milwaukee manager Ron Roenicke was also shown the door by Holbrook. The incident began when the right-hander raced to cover first base on a ground ball off the bat of Houston second baseman Jose Altuve. The two reached the bag at exactly the same time. Holbrook gave the safe sign and Greinke slammed the ball into the ground in disgust. The umpire almost immediately gave Greinke the hook. The two exchanged words before Roenicke raced from the dugout to voice his displeasure.
