Tom Heathcote kicked through four penalties to make it four wins from four as Worcester beat Irish 12-6 at Sixways
Two Heathcote penalties gave Warriors a 6-0 lead at the interval
The fly-half added two kicks, but Irish earned a losing bonus point through Greig Tonks
Worcester Warriors all but ended their Premiership relegation fears with a fourth consecutive win in an error-strewn bottom-of-the-table clash against London Irish at Sixways.
Four kicks from Tom Heathcote were enough for Worcester, who have won four Premiership games in a row for the first time in their history while the Exiles wasted several promising situations in a game they had to win.
The pattern continued after the break with Blair Cowan and Ciaran Hearn both dropping the ball when they looked to be away.
Greig Tonks slotted two penalties – including one in the 78th minute – to at least give the visitors something from the game.
The Exiles, who are four points behind second bottom Newcastle, now only have four games remaining and have also played a game more than the Falcons.
Worcester’s win earned them a fourth consecutive Premiership win for the first time and takes them 16 points clear of the foot of the table.
