White capped off a fine year in the TAC Cup, winning the club champion award.
“Mitchell predominantly played as a rebound defender, culminating in a best and fairest for the Stingrays this year. He’s a long, raking left-foot kick, who has really good defensive nous,” national recruiting manager Jason Taylor told melbournefc.com.au.
Melbourne now has a full list of 44 players for 2014, including 40 on its primary list and four rookies.
Aaron Vandenberg and White join midfielder James Harmes and forward/ruckman Max King as rookies for 2015.
Melbourne has now added 11 new players to its squad for next year. Vandenberg and White join father-son choice Billy Stretch (Glenelg); trade period selections Sam Frost (Greater Western Sydney), Jeff Garlett (Carlton), Heritier Lumumba (Collingwood); delisted free agent Ben Newton (Port Adelaide) and NAB AFL Draft picks Angus Brayshaw (Sandringham Dragons), Alex Neal-Bullen (Glenelg), Oscar McDonald (North Ballarat Rebels) and Christian Petracca (Eastern Ranges).
