A brilliant pitching performance by Andrew Chesterton carried the Doncaster Dragons to an important win over Sunshine at Altona on Tuesday night.

Chesterton, rapidly becoming Doncaster's midweek specialist, never gave the Eagles a chance to get into the game, which the Dragons won 4-1.

He pitched a complete seven-inning game without allowing an earned run, striking out six and walking three.

On a windy night at Altona, offence was always going to be at a premium. The Dragons and Eagles each had only four hits, but  Doncaster's hitters had many more productive plate appearances, reaching base nine times via walks or hit-by-pitches.

After a scoreless two innings, the Dragons got on the scoreboard in the third. Scott Couling singled, Callum Lethborg reached on a  fielding error and Mitch Ellis singled to load the bases for Nic Unland, whose RBI groundout drove in Couling for the first run of the game. Scott Carr also hit an RBI groundout to score Lethborg and give his team a 2-0 lead.

After the Eagles halved the deficit with an unearned run in the fourth inning, the Dragons hit back immediately. With two out, Unland walked and Carr singled. Both then scored easily on the biggest hit of the night, a double by Ben Utting.

The Dragons had a chance to build on the lead in the seventh inning. Carr was hit by a pitch, then Utting and Brendan McDonald walked to load the bases, but all three were left stranded.

No matter. Chesterton cleaned up the Sunshine hitters in the bottom of the seventh to ensure the win and the three-game season sweep of the Eagles.

Can the Dragons make it three wins in a row? It won't be easy, as next on the agenda is a game against powerhouse Essendon at Deep Creek on Saturday.
