SYDNEY Blue Sox will enter the final round equal first with Canberra after sharing their series 2-2 with Cavalry in the Australian Baseball League.
Canberra tied the series with a win on Sunday at Blacktown International Sportspark.
It took an extra innings to decide the round 12 four-game set.
In the bottom of the 12th, Ryan Stovall raced home with the game-winning run on a controversial play at the plate.
After the Blue Sox forced extra innings by tying the game at 3-3 in the top of the ninth, each side had a multitude of chances.
With the bases loaded and one out in the bottom of the 12th inning, Canberra's Jack Murphy chopped a grounder to Sox first baseman Boss Moanaroa.
He threw to home plate, where his throw beat the runner from third base, Ryan Stovall.
After a few seconds of contemplation, the home-plate umpire called Stovall safe.
Amid Sydney's vehement protests, the Cavalry walked off for the second time in this four-game series.
"Our guys battled so well today, against both Canberra and the hot weather," Blue Sox manager Jason Pospishil said.
"To come back twice showed great guts."
