Negrych is 49th in the minors in OBP. Of the names ahead of him Buxton (19) is a legitimate prospect, as are Sano, Franklin, Rendon and Garin Cecchini. Former major leaguers that are ahead of him are Brian Bogusevic, Tim Federowicz, Ruben Rivera, Scott Van Slyke, Brandon Snyder, Zach Cox, and DJ LeMahieu. What Negrych is doing is impressive but it's still a small sample size and when you consider the .264/.357/.391 number he put up in AAA last year (which is close to his career numbers in the minors) he's not going be more than an injury backup. 30 years of watching ball is what tells me that.
