Plymouth Albion secured their first Championship win under new director of rugby Pete Drewett as they ground out a win over Doncaster Knights.
Tyson Lewis was the Albion hero, scoring two tries in three minutes midway through the first period as Albion threatened to run riot.
The Knights did well to hold Albion to 15-3 at the interval but improved with the wind behind them after the break.
Albion's James Love and Knights' David McIlwane traded second-half penalties.
The win keeps Albion's slim hopes of catching Knights in the final play-off place alive.
