Andriy Yarmolenko scored two first-half goals as West Ham United defeated Everton 3-1 to claim their first Premier League victory of the season.
Marko Arnautovic extended the lead in the second half as West Ham avoided becoming only the fifth team to open with five consecutive Premier League defeats.
Yarmolenko, who joined West Ham from Borussia Dortmund in July, opened the scoring in the 11th minute.
With West Ham on the counterattack, Pedro Obiang played a ball over the top of the Everton defence that Arnautovic ran under before setting up Yarmolenko for 10 yards for his first goal with the club.
The lead doubled 20 minutes later after Everton goalkeeper Jordan Pickford's giveaway, with Yarmolenko pivoting past Kurt Zouma and Lucas Digne to fire into the top left corner.
Everton pulled one back in first-half added time when Gylfi Sigurdsson scored from a header after Jonjoe Kenny lifted it into the mixer, but West Ham silenced Everton's comeback attempt when Arnautovic converted easily in the 61st minute for his third goal of the season.
The hosts nearly scored a second in the 84th minute, but Oumar Niasse rung the crossbar from a volley six yards out.
