2010-11: Wiercioch had a challenging initial season adjusting to the speed and size of professional hockey. He was down on the blue-line depth chart but did improve as the second progressed finishing with four goals and 14 assists in 67 regular season AHL games and an assist in 15 Calder Cup contests he suited up for. The Senators brought him up for an eight game audition near the end of the NHL season where he handled himself well and contributed two assists.
2011-12: Wiercioch's second pro season was interrupted by a serious throat injury suffered in a December game when he was hit by a clearing attempt while skating for Ottawa's AHL affiliate Binghamton. He returned to the lineup at the end of January and gradually worked back to the level at which he was playing before the injury.

He was re-signed by Ottawa to a three-year contract as a restricted free agent in July of 2013.
Wiercioch has a nice blend of size and skill. He’s a good all-round defenseman who can play in many different situations. A mobile puck moving defenseman, he has very good hands but needs to improve his skating. Additional size and strength will need to be added to become more effective against higher competition. Has the smarts and know how to be effective.
