Peter Chiarelli is on a mission to stock up on the back end.
The Edmonton Oilers general manager acquired defenceman Eric Gryba from the Ottawa Senators at the NHL Draft Saturday in exchange for prospect Travis Ewanyk and the 107th overall pick in the draft.
Ottawa used that selection to snap up defenceman Christian Wolanin.
Earlier in the day, Chiarelli improved in goal by trading picks for goaltender Cam Talbot, and on Friday he traded two draft picks to acquire defenceman Griffin Reinhart from the New York Islanders.
Gryba essentially replaces the left-shooting Matt Marincin — dealt Saturday to the Toronto Maple Leafs — on the Oilers’ roster.
The right-shot, stay-at-home Gryba was originally drafted in the third round of the 2006 draft by Ottawa. The 27-year-old Saskatoon native has scored four goals and added 25 assists in 165 career games spread over three seasons with the Senators.
Gryba carries a cap hit of $1.25 million through 2015-16.
Ewanyk, a 22-year-old centre, has played his last two seasons with AHL Oklahoma City. In 2014-15, he registered three goals, five assists and racked up 120 penalty minutes in 69 games.
