Kolarek allowed six runs (four earned) on two hits and two walks while striking out one over two-thirds of an inning during Tuesday's loss to the Twins.
Kolarek served as the opener for the Rays and allowed the first three batters to reach base -- though one reached via error -- before giving up a grand slam to Eddie Rosario. The 30-year-old has thrown two innings over four spring appearances, and has given up nine runs (seven earned) on seven hits and four walks.
