I thought that was his nickname from last year during the stupid nickname jersey weekend Yeah. Its what the team called him last year because of how he looks when he runs. Found this in an interview with rosiak in the JS last summer. Q. Another one of your talents is your famous "raptor" run. Where did that come from? A. Really, it started with Tim Dillard. I have a pretty slouched run, and so he kept on saying I ran like a raptor. Then every time I'd do sprints near the relievers where he'd be stretching, he'd just go, "Rawwwwwwwwwr!" Eventually he had me come in as a Dubsmash guest and do the raptor runs in the background, and I guess it just took off. Then last year Mike (Vassallo, Brewers senior director, media relations) asked me what I wanted my music to be and I was like, "I don't really care." He goes, " 'Jurassic Park' theme song all right?" And I was like, "OK." (laughs) That's how it happened, pretty much."
