Dyachenko, born in Russia, finished his third season with DC United in 2008, playing in 42 games and logging 1,452 minutes with one goal and three assists. He was selected 31st overall in the 2006 MLS SuperDraft out of UNLV.
“I am extremely happy that Rod Dyachenko will be in a Thunder uniform this season,” said Thunder head coach Donny Gramenz. “I watched Rod perform several times last season with DC United and he is going to raise the level of the technical and tactical understanding of our midfield. He will bring an athletic and physical presence to our midfield that we have been missing.”
While at UNLV, Dyachenko was named the 2005 Mountain Pacific Sports Federation Player of the year following his senior season. He also earned his third consecutive All-MPSF First Team honors by leading the Rebels with eight goals and one assist. He ended his collegiate career with 23 goals (seven game winners).
Costanzo joins the Thunder after finishing his senior season at Maryland where he helped to guide the Terrapins to the NCAA Division I championship. In his senior season the defender started all 26 games for Maryland on the way to the championship. He played his freshman season at Penn State before transferring to Maryland for his sophomore season.
“I watched Richie Costanzo play several times for the University of Maryland this past season and one of those times was the Terps hoisting the National Championship,” said Gramenz. “Richie brings leadership, a blue-collar mentality, and a great understanding of the outside defender position. As a coach, I appreciate not only his ability to play the game but all the selfless things he does off the ball to make his team succeed.”
