Angels' Magneuris Sierra: Loses roster spot

The Angels designated Sierra for assignment following Tuesday's 4-3 win over the Athletics, Rhett Bollinger of MLB.com reports.

Catching prospect Logan O'Hoppe will be called up from Triple-A Salt Lake on Wednesday to take Sierra's spot on the 40-man roster and 28-man active roster. Sierra had been up with the big club since late July and slashed .165/.200/.242 over 65 games while mostly serving as a reserve outfielder.
