In a no-risk move aimed to bolster their depth up the middle for training camp, the Washington Capitals have signed center Derek Roy to a professional tryout contract, according to Mike Vogel of the team Web site.

A former second-round draft pick entering his 12th NHL season with 738 appearances to his name, Roy spent 26 games with Nashville before getting shipped to Edmonton for Mark Arcobello in late December. For the Oilers, his sixth stop since 2011-12, Roy registered 22 points in 46 games, and figures to challenge for a bottom-six role in Washington, where the center situation remains up for grabs. Over his past four seasons, the 32-year-old has posted an even-strength shot differential rate above 50 percent three times, per

According to Coach Barry Trotz, speaking Saturday at the 2015 Lightning Prospect Tournament in Estero, Fla., forwards like Michael Latta, Brooks Laich and Andre Burakovsky are all expected to work at both wing and center during the preseason, the partial product of center Nicklas Backstrom’s offseason hip surgery, which will likely keep the top-line anchor sidelined until at least the season-opener on Oct. 10.

“I don’t expect him to be playing in any of the exhibition games,” Trotz said. “I really don’t. If they tell me yes, then I’ll be happy.”

The Capitals are scheduled for their off-ice physical testing on Thursday and their first on-ice session of training camp the following afternoon. The nature of the PTO allows the Capitals to release him at any time without financial consequence or, if Roy impresses enough, to sign him to their squad via a standard contract.
