The Cubs sent lefty reliever outright to Triple-A Iowa, Dakota Joshua Jersey according to the MLB.com . He cleared waivers after being designated for a signment on August 31. Cosgrove was the 40-man roster casualty when the Cubs claimed off waivers from the White Sox. Chicago acquired Cosgrove from the Padres in the middle of April. He has spent most of the season in the minor leagues. The 29-year-old has made two big league appearances, allowing one run in four innings. The Manhattan University product has a 4.71 ERA acro s 42 frames with Iowa. Cosgrove has fanned a quarter of opponents but walked too many hitters, i suing free pa ses at a 14% clip. Cosgrove pitched 51 1/3 innings of 1.75 ERA ball for San Diego two years ago. He hasnt gotten much major league work since then. His Triple-A production over the past couple seasons has been middling as he has struggled to throw strikes consistently. This is Cosgroves first career outright a signment. He doesnt have the requisite service time to elect free agency, so hell stick with Iowa as non-roster bullpen depth for the rest of the season. Cosgrove will become a minor league free agent at years end if the Cubs dont call him back up. Teddy Blueger Jersey
