Luke Patrick Ball (born 25 May 1984) is a former professional Australian rules football player who played for the St Kilda and Collingwood football clubs in the Australian Football League. From 2003 to 2009 he played 142 games for the St Kilda Football Club where he was captain in 2007 and best and fairest and All-Australian in 2005. He is one of the only players in AFL history to have played in four consecutive grand finals for two clubs; for St Kilda in 2009 and for Collingwood in 2010, the 2010 replay and 2011.
Ball is the younger brother of Hawthorn player Matthew Ball, both of whom played for the local football club at Ashburton in their junior years. Both brothers and little sister Sophie grew up with their parents in the Melbourne suburb of Glen Iris, attending St Roch's Primary School. His father, Ray Ball, was also a footballer, who played for Richmond and South Melbourne.
He was drafted to the St Kilda Football Club in 2001 with the priority pick (number 2 overall) in the AFL draft. The draft that year was known as the "super draft" and Ball was taken behind Luke Hodge and ahead of Chris Judd. He debuted in 2003 after having injury problems and choosing to play football for Xavier College in his final school year. Ball finished his schooling with a VCE ENTER score of 98.8.
After missing his initial debut season, Ball was a Rising Star nominee in his debut season of 2003. He played 16 games and averaged 15.8 disposals per game in a solid first season.
Ball played in St Kilda's 2004 Wizard Home Loans Cup winning side, the club's second pre-season cup win.
2004 was a big year for Ball, coming second in St Kilda's Trevor Barker Award for the club's best and fairest player. In 2004, Ball averaged 20 disposals and 5 tackles per game. He also pushed forward to boot 17 goals for the season.
In 2005 Ball won the Trevor Barker Award for St Kilda's best and fairest player, tying with Steven Baker.
Ball was also recognised for his excellent season with selection in the 2005 All-Australian Team as a midfield player, his first All-Australian Team award. He averaged 22 disposals and 5.3 tackles per game.
When Nick Riewoldt was injured in the opening round of the 2005 season (and consequently missed the next five weeks), Ball was appointed as acting captain.
In 2006 Ball was announced as the St Kilda captain, succeeding Nick Riewoldt under the Saints' then rotational captaincy policy. Early in the season groin problems kept the young captain from performing at his best, but he was cleared in mid-June of having Osteitis pubis from which many media outlets had claimed he was suffering. Ball's second half of the season saw improvement in his game. He was slightly down on his 2005 form, but still managed to average 21.9 touches and play 21 games in his first season as St Kilda captain.
In 2007 Ball was co-captain along with Lenny Hayes and Riewoldt. He played a total of 18 games of the home and away season - picking up 345 disposals, 5 goals and 91 tackles. Although well down on his 2005 form, he played a valuable role in the team and solidified his reputation as a "hard-nut" and core member of St Kilda's midfield.
Ball played in St Kilda's 2008 NAB Cup winning side - St Kilda's third pre-season cup win.
In 2008 Ball again missed only four games with injury - picking up 392 disposals, 7 goals and 107 tackles. A hamstring tear late in the season caused him to miss the finals series.
Ball played in 17 of 22 matches in the 2009 AFL season home and away rounds in which St Kilda qualified in first position for the finals, winning the club's third minor premiership.
St Kilda qualified for the 2009 AFL Grand Final after qualifying and preliminary finals wins. Ball played in the grand final when St Kilda was defeated by 12 points.
At the end of 2009 season Ball requested to be traded to Collingwood. A deal between the two clubs, however, was not settled before the trade week deadline despite mediation from the AFL. On 10 November 2009 he officially left St Kilda and nominated for the national draft. On 26 November 2009 he was drafted to Collingwood with their first pick (number 30 overall).
Ross Lyon described the departure of Ball in early 2010:
"Look, Luke Ball in simple terms is this: Luke had a rich history with St Kilda, but the AFL is a professional sport and expectations are often set and not met by club or player. Clearly, along the line, there has been some expectations not met on both sides of the fence. Luke is a Collingwood player now and that's his future and it's not for me to talk about our expectations. During the year he got dropped, then he matched our expectations (and returned) and then obviously there was some expectations from Luke that we weren't meeting and he moved on. That's where that sits. That (the failed trade to Collingwood) was the decision we made at the time and we stand by that. Did we want nothing for him? No. Let's be clear on this, Luke wasn't traded or delisted. Luke walked out on St Kilda, of which he had a million dollar-plus contract on the table. "
