Unfortunately named pitcher leaves Cubs contract to join new team

Aaron Bummer does not have the ideal name for a pitcher.He's also no longer a member of the Chicago Cubs' organization.The New York Post's Jon Heyman reported Friday that Bummer has opted out of his minor league contract and is now a free agent.Bummer likely had a clause in his contract as a veteran that allowed him to pursue a new opportunity if he hadn't been called up to the major leagues by a certain date.The lefty relief pitcher first went to rookie ball for a couple outings with the Cubs after signing, throwing 2.0 scoreless innings.He then moved up to Triple-A Iowa, where he gave up four runs in 4.0 innings.Bummer had previously pitched 19 games in the majors this season for the Atlanta Braves, but he had just a 7.63 ERA there.MORE: How Jordan Walker overcame the bust labelDespite t
