In round 8, 2007, in a match against Hawthorn, Montagna suffered a broken jaw but only missed one week with the injury. Although 2007 was the first since 2003 that St Kilda had missed out on playing in the finals series, it was the season that saw Montagna become a top line AFL footballer. Montagna played consistently throughout the season and continued the improvement he had shown in 2006. He played an accountable and hard running role through St Kilda's midfield, averaging 24 disposals and 3 tackles per game and kicking 10 goals for the year. Some of Montagna's highlights for the year included best on ground performances against the Kangaroos, Richmond and Hawthorn in the second half of the year. Montagna was rewarded for his efforts with a third-place finish in St Kilda's 2007 best and fairest.
