Summary West Ham and Aston Villa stemmed the flow of upsets in the fourth round of the FA Cup
BRISTOL: (AP) - West Ham and Aston Villa stemmed the flow of upsets in the fourth round of the FA Cup by securing wins over awkward lower-league opposition on Sunday.
Senegal striker Diafra Sakho came off the bench and scored an 81st-minute header to earn West Ham a 1-0 victory at Bristol City, which is third in English football s third tier.
Villa had a tougher assignment against second-tier leader Bournemouth but came through with a 2-1 home win, with new signing Carles Gil with his first goal since his move from Valencia and Andreas Weimann scoring for the Premier League side.
Chelsea and Manchester City were among five teams in the Premier League s top nine to be eliminated on Saturday on one of the most astonishing days in the famous competition s history.
West Ham and Villa have redressed the balance and Arsenal will look to become the third top-flight team to progress to the last 16 on Sunday when it visits second-tier Brighton.
West Ham toiled in the first half at Ashton Gate, clearing two headed attempts off the line, but improved after the break. Sakho, who entered as a 57th-minute substitute, struck the bar with a fierce shot before meeting Andy Carroll s cross with a far-post header from close range.
"Bearing in mind what has happened this weekend, it is a big result for us," West Ham manager Sam Allardyce said.
With Villa struggling in the Premier League and Bournemouth flying in the League Championship, their matchup had all the ingredients of another cup upset and the visitors had Villa at full stretch for much of the game.
However, Villa was clinical in front of goal, surprisingly given it is the lowest-scoring team in all four divisions in England, and Gil broke the deadlock by finding the top corner from 25 meters in the 51st.
Weimann s steered home Alan Hutton s cross to make it 2-0 in the 71st before Callum Wilson s injury-time response for Bournemouth.
It completed a positive day for Villa, with the club announcing that star midfielder Fabian Delph has signed a new 4½-year contract.
