Sunderland continued their recent revival with a 4-1 win at Wigan Athletic on Tuesday.
The eventual winners entered the match with three victories from their first five matches under new manager Martin O'Neill, including a dramatic 1-0 home win over table-toppers Manchester City on Sunday.
Their success continued at the DW Stadium as Craig Gardner, James McClean, Stephane Sessegnon and David Vaughan all scored for Sunderland.
Wigan started the brightest and Crusat burst down the left to set up Hugo Rodallega in the early stages, only for the Colombian to turn the ball over.
Jordi Gomez forced Sunderland goalkeeper Simon Mignolet into a smart save while Ben Watson and David Jones both hit the woodwork in the same move.
Crusat hobbled off after a challenge from Vaughan and was replaced by Victor Moses for the hosts, who were quickly made to pay for wasted opportunities.
It was Gardner who opened the scoring with an unstoppable free-kick that left Wigan shot-stopper Ali Al Habsi with no chance.
The goal came three minutes into first-half stoppage time and Sunderland scored again shortly after the resumption as McClean initially saw his header from a Vaughan cross saved, before he headed the follow-up into the back of the net for his first Premier League goal.
Rodallega kept Wigan in the match on 62 minutes though when he turned on the edge of the area and beat Mignolet with his powerful low drive.
But just 11 minutes later and the game was all over as Nicklas Bendtner picked out Sessegnon with a superb cross, meaning all the Benin international had to do was turn the ball into the net.
And Vaughan put the icing on the cake with 10 minutes to play as he lashed a left-foot strike into the top corner from outside the penalty area.
The result saw Wigan's winless record at home stretch to eight Premier League matches while Sunderland made it two victories in a row on the road and moved into the top half of the table.
