Two late goals helped Gimnasia to a long-awaited first victory under recently appointed coach Diego Maradona on Saturday.
Victor Ayala and Matias Garcia scored in the 83rd and 87th minutes, after opponents Godoy Cruz had had two men sent off.
The goals gave Gimnasia a vital 4-2 away win in their bid to stave off relegation from Argentina's Superliga.
The win was a huge boost to Maradona, the famed World Cup winner who took over at the club last month.
After three successive defeats under Maradona, the win lifts Gimnasia off the bottom of the league and on to four points from nine games, one ahead of Saturday's rivals.
