Rockies' Brandon Barnes: Designated for assignment Monday

Barnes will be designated for assignment Monday, The Denver Post reports.

Analysis:

Barnes will cede his roster spot to 22-year-old outfielder David Dahl, who may step in as the regular left fielder. The 30-year-old Barnes could pass through waivers unclaimed, as he has 22 hits and 30 strikeouts in 100 at-bats this season.
