The International Scouting Service's May prospect rankings were released on Wednesday and while positioning were shuffled around, the top 10 players remained intact.
Portland defender Seth Jones remained as the top prospect, followed by Halifax Mooseheads teammates Nate MacKinnon and Jonathan Drouin. Russian forward Valery Nichushkin and Finnish forward Sasha Barkov rounded out the top five.
Sault Ste. Marie blueliner Darnell Nurse remained in sixth while Swedish forward Elias Lindholm moved up to seventh, bumping London Knights defender Nikita Zadorov down to eigth.
The ninth and 10th rankings remain the same as the month of April, seeing Ottawa 67s centre Sean Monahan and London's Bo Horvat completing the top-10, respectively.
The biggest leap up the rankings this month has been Steve Santini and Madison Bowey. Both players moved up five spots to 17th and 22nd, respectively, for the month of May.
Santini, who spent the 2012-13 season playing for the U.S. NTDP squad, has been described by the prospect report as someone who "does all the little things on the ice that can go easily unnoticed to the untrained hockey eye."
The report also noted that Bowey, who played for the WHL's Kelowna Rockets this season, has good linear speed with decent mobility but is relentless on his man, on and away from the puck.
