TEMPE, Ariz. — The Los Angeles Angels have returned reliever Christian Friedrich to the Colorado Rockies due to concerns over an undisclosed medical issue.

The Angels claimed the left-hander off waivers from the Rockies two weeks ago.

The Angels said Friday night that a physical raised concerns over "Friedrich’s ability to play at his accustomed level." The commissioner’s office then allowed the Angels to send Friedrich back to Colorado.

The 28-year-old Friedrich is 5-16 with a 5.81 ERA in parts of three seasons with the Rockies.

The move leaves the Angels with an open spot on the 40-man roster.
