Swarzak, 35, pitched in six games earlier this year with the Diamondbacks. He allowed five runs over 4 2/3 innings, striking out four while walking just one. Arizona cut Swarzak loose at the end of April, and he latched on with the Royals not long thereafter on a minor league deal. He got off to a fantastic start with Triple-A Omaha, punching out 14 of 33 batters faced (42.4%) while not issuing a walk. He allowed three runs (two earned) in 9 1/3 frames as a Storm Chaser before earning his way back to the big leagues.
Bolaños went on the IL earlier this week with a forearm strain. It’s not yet clear if that’ll require surgical repair, but he’s now out until at least mid-August. The 24-year-old was off to a strong start to the year, striking out ten while issuing just a pair of walks over 6 1/3 relief innings.
