Rangers president of baseball operations Jon Daniels said last week that Palumbo will likely be shut down for the rest of the season after he picked up an undisclosed injury at Triple-A Round Rock in late June, Levi Weaver of The Athletic reports.
Palumbo missed time in May and June due to a back strain, but it's unclear whether his latest health setback is related to that injury. He last appeared in a game for Round Rock on June 24 before being placed on the 7-day injured list two weeks later. Daniels suggested that Palumbo's shutdown will just be extended through the summer, so the 26-year-old lefty could be ready to go for the Rangers' fall instructionals.
