The Twins will send right-handed pitchers Kyle Gibson and Michael Tonkin, as well as left-handers Logan Darnell and Caleb Thielbar to Arizona. They will be joined by catcher Chris Hermann and outfielders Evan Bigley and Nate Roberts.
Gibson -- a first-round pick of the Twins in 2009 -- is currently with Triple-A Rochester and in his first season since coming off Tommy John surgery last November. He lost his only start with the Red Wings, giving up four runs in three innings against Buffalo on Aug. 25. He posted a 2.57 ERA in two rehab starts with Class A Fort Myers earlier this month.
The Javelinas will play their home games at Peoria Sports Complex and will be coached by Dusty Wathan, who currently manages the Reading Phillies, Philadelphia's Double-A affiliate. Prospects from the Mariners, Padres, Phillies, and Reds will join the Twins' seven players with the Javelinas.
