Phil Kessel heading to Pittsburgh via multiplayer trade with Toronto

— -- The most buzzworthy NHL name of the summer is on the move, with the Toronto Maple Leafs shipping star winger Phil Kessel to the Pittsburgh Penguins, a source confirmed to ESPN.com's Pierre LeBrun.

The Leafs are sending Kessel, forward Tyler Biggs, defenseman Tim Erixon and a second-round 2016 draft pick to the Penguins in exchange for defenseman Scott Harrington, forwards Kasperi Kapanen and Nick Spaling, a first-round 2016 draft pick and a third-round selection in '16, the source said.

In addition, Toronto will retain 15 percent of Kessel's salary, or $1.2 million annually.

Penguins general manager Jim Rutherford made no secrets about his wish to go big-game hunting in the hopes of landing a top-six winger. Though he was unsuccessful in doing that during last weekend's draft, his patience ultimately paid off as he was able to land Kessel on the first day of free agency.

The 27-year-old Kessel collected 25 goals and 36 assists this past season for the Leafs, his sixth with the team.

He was rumored to be on the move for some time now, especially with the Leafs in rebuilding mode and the team looking to complete an overhaul in wake of another abysmal season. They finished 30-44-8, leading to them hiring Mike Babcock as coach.

Team president Brendan Shanahan said before the draft that the Leafs would not make any move hastily when it came to Kessel, though he characterized the interest in the five-time 30-goal scorer as strong.

Kessel joins Penguins superstars Sidney Crosby and Evgeni Malkin, though it is unclear which centerman he's likely to slot in with when the season begins.

Kessel has five years remaining on a deal that carries a cap hit of $8 million annually. Though the Pens likely will face some cap issues in the future, Rutherford was able to pull off the deal without sending back either of the team's top two young defenseman, Olli Maatta and Derrick Pouliot.
