Drafted in the 2nd round (50th overall) by the Washington Nationals in 2009 out of California College.
He was a very well thought of prospect. He did not have a lot of power, but projected as a solid major league outfielder with plus-plus speed. He was the Nationals #7 prospect after the 2009 season, #21 after the 2010 season, and #20 and the 2011 season. But he was never able to find a home on a major league roster, and was selected by the Red Sox in in the 2012 Rule 5 draft. The Red Sox immediately flipped him to the Tigers, where he immediately ranked as Detroit’s #20 prospect.
At this point it was clear that Kobernus was not going to develop power, but still projected as a utility player with lots of speed–something any team could use.
In March 2013 Kobernus was returned to Washington, and he would get some time in the majors. After the 2013 season he was still ranked the Nationals #19 prospect.
That would be the high point of his career. He struggled in 2014, and was released by the Nationals in the 2015 pre-season. Signed with the Giants for the 2015 season, had a poor season in both High-A and AAA, and was released in November.
