The Minnesota Twins have made significant roster changes, designating pitcher Trevor Richards for assignment and placing Joe Ryan on the 60-day injured list, effectively ending their regular seasons. Richards, a trade deadline acquisition, struggled with control issues, pitching 13 innings with a 4.15 ERA, 11 walks, and 7 wild pitches. Ryan, recovering from a Grade 2 teres major strain, will not be eligible to return until October 9, missing the rest of the regular season. The moves create roster spots for Caleb Boushley, called up from Triple-A St. Paul, and Michael Tonkin, claimed off waivers from the Yankees. Twins manager Rocco Baldelli acknowledged the difficult nature of these decisions, emphasizing the need for effective pitching during a pennant race. Despite Ryan's optimism about his recovery, his return this season remains uncertain.
