Toronto Blue Jays third baseman Brett Lawrie was thrown out in the bottom of the third inning after he was called out on strikes by home plate umpire Dan Bellino.
Lawrie flipped his bat, threw down his helmet and tossed his batting gloves behind him as he walked away from the plate. He was given the heave-ho by Bellino, who also ejected Jays' manager John Gibbons when the skipper came out to argue.
Crew chief Wally Bell told a pool reporter after the game that it was Lawrie's tossing of the batting gloves that prompted Bellino to run him, calling it poor baseball etiquette.
Lawrie's older sister immediately went on her Twitter account (@DanielleLawrie5) to express her displeasure.
"The umps these days in @mlb can suck it... Some of the worst calls I have ever seen have been this 2013 season," she tweeted, adding the hashtag "#callthegamerightdouches"
In subsequent tweets, she said she wasn't necessarily defending her brother's actions, but she understands the desire to "show someone up that's that terribe (sic).
"I'm not saying what my brother did was RIGHT at all, I'm saying these umps are horrific and are not held accountable," she tweeted.
Danielle Lawrie is a world-class ball player in her own right. The native of Burnaby, B.C., pitched for Canada's women's softball team at the Beijing Olympics in 2008. She was the U.S. national collegiate player of the year in 2009 and 2010, and led the University of Washington to the Women's College World Series championship in 2009.
Friday's ejection was the first for Brett Lawrie this season. Last year, he was suspended four games after a tirade that saw him throw his batting helmet, which bounced off the ground and struck umpire Bill Miller in the leg.
