Cowser went 2-for-4 with a home run, a walk and two RBI in Sunday's 10-5 win over the Rangers.
Cowser added to Baltimore's early lead by taking Kumar Rocker deep for a solo homer in the second inning, giving him nine home runs on the season. He later drew a bases-loaded walk in the ninth to secure his first multi-RBI performance since June 21. Cowser had struggled mightily over the past month entering Sunday, batting just .121 across his previous 29 games with only one RBI.
