The Predators have made their second waiver claim in as many days, adding forward Zach Boychuk — a former first-round pick — on waivers from Pittsburgh. The move comes one day the Predators picked up forward Bobby Butler on waivers from New Jersey. Butler has 39 points in 108 NHL games. “The bottom line is that it’s just not working with our current group and we have to make some changes,” Predators general manager David Poile said. “Butler can score. He has proven he can score at the NHL level. He can score like dynamite in the minors. “Boychuk has scored really good in the minors. Can it translate to the NHL? We’ve had good success with (acquiring) younger players and developing them. We’ll find out.” In order to remain at the NHL’s roster maximum of 23, the Predators have placed forward Brandon Yip and defenseman Hal Gill on injured reserve. The 23-year-old Boychuk was the 14th overall pick in the 2008 draft, but has yet to make an impact on the NHL level. In 80 career NHL games since 2008-09, he has posted 18 points (seven goals, 11 assists) with Pittsburgh and Carolina. He didn’t record a point in eight NHL games this season. Boychuk, 5-foot-10 and 185 pounds, started the 2012-13 season with Carolina’s primary developmental affiliate, the Charlotte Checkers, amassing 32 points (16, 16) in 37 games.
