Port Adelaide beats Sydney in the upset of the AFL season Justin Westhoff kicked a crunch last-quarter goal. Picture: Simon Cross EMERGING star Chad Wingard inspired Port Adelaide to the upset of the season, a slogging 18-point comeback against Sydney. The Power trailed at three-quarter time but Wingard triggered a late surge as Port won 10.12 (72) to 8.6 (54) at a sodden AAMI Stadium. SuperCoach scores, stats and more Port ruined the comeback game of Sydney's prized recruit Kurt Tippett, who kicked a goal in the first minute and finished with two in an ominous debut for the Swans. But in wet and windy conditions, Port kicked five goals to two in the last term to stun the Swans and climb into the top eight. Wingard booted three goals, including two in the tense final stanza, while Port's acting captain Brad Ebert, Matthew Broadbent and veteran hard-nuts Dom Cassisi and Tom Logan revelled in the heavy going. The Swans were superbly served by midfielders Josh Kennedy and Jarrad McVeigh and backman Nick Malceski was prominent. But the flag fancies lost ex-skipper Adam Goodes, who was substituted at three-quarter time with an injured right knee.

The 19-year-old was instrumental in delivering first-year coach Ken Hinkley his greatest win after the Power slipped behind early as Tippett took centre stage. Tippett took a mark just 11 seconds into his playing career at Sydney, and then converted, in an impressive comeback after an 11-match suspension for his illegal 2009 contract with his former club, Adelaide.
