The fit-again Watford winger earned 19 points in his first start since Gameweek 23, rewarding the faith of his 0.6 per cent ownership.
Sarr has eight attacking returns in as many starts under Nigel Pearson but it is at home where he has really excelled.
He has averaged 9.4 points per match at Vicarage Road for the Hornets' head coach, scoring four goals and supplying three assists in five appearances.
Sarr was among a number of successful differentials for the reduced Gameweek, with his team-mate Troy Deeney (£6.2m) also producing a double-figure return.
The Watford striker earned 11 points thanks to a goal and an assist.
The wing-back scored both his side's goals, taking his tally to 24 points in the last two Gameweeks.
Alonso has produced attacking or defensive points in all eight of his appearances in Frank Lampard's starting XI this season.
Lewis scored the decisive goal in the Canaries' 1-0 win over Leicester City on Friday evening, with Aarons supplying the assist.
He is the only player owned by more than 10 per cent of managers to score in excess of three points in Gameweek 28 so far.
A number of overlooked West Ham United attackers also excelled over the weekend.
