[3] After a difficult climb back from his injury, Trengove made his AFL debut in the opening round of the 2010 season after playing in the 2010 NAB Cup.

This was arguably Trengove's best match so far, as he collected 11 disposals, 8 hit-outs, 6 tackles, 1 goal and 3 marks (one of them with seconds to go which ensured the team's win).

Also in 2011, there was a lot of speculation that Trengove would leave the club and move back to his home state of Victoria because of the current on-field and off-field dramas that were unfolding with the Power.

He along with Travis Boak were jointly crowned the John Cahill Medallist at season's end, the first time that there had been a tie at the club's best and fairest award.

Trengove had another injury interrupted season in 2015 and as a result was never quite able to produce the sort of football that had previously seen him as a dominant presence in the back half.
