On June 6, Texas abruptly designated Ponson for assignment for what general manager Jon Daniels called "disrespectful and adverse reactions to situations unbecoming of a teammate." Daniels added, "We don't feel Sidney deserves to be here or wants to be here. We're not going to get into details other than to say we're clearly trying to put together a team here, in a true sense of the word. Based on some recent comments and other such things, it was pretty clear that he did not want to be part of that, and it's something we're not going to tolerate."
