Fremantle have officially added GWS ruckman Rory Lobb to the club for next season, sealing the deal with just hours remaining on the final day of the trade period.

Lobb will join the Dockers along with picks 14 and 43 in exchange for picks 11 and 19, that will go to GWS.

The 25-year-old has come into his own over the past three seasons, after playing just 11 games in his first two years at the Giants.

Lobb has played at least 19 games per season since 2016, and spent more time in the ruck in 2018, averaging a career-high 20.7 hitouts per game, while also kicking 11 goals on the season.
