LONDON: Cardiff were left in control of their own destiny as they took a giant stride towards automatic promotion to the Premier League with a 2-0 win away to Hull on Saturday.

Cameron Jerome gave the Rams an early lead but Lewis Grabban equalised six minutes from time.
At the other end of the table, Burton remained in the relegation zone despite a 2-0 win over drop rivals Bolton.
Now Nigel Clough's side must get a get a result at Preston on the final day after Barnsley beat Brentford 2-0 to move out of the bottom three by virtue of their vastly superior goal difference.

Che Adams gave Birmingham the lead at QPR but the London club hit back to win 3-1 thanks to goals from Bright Osayi-Samuel, Ilias Chair and Matt Smith.
With 20 minutes left, Reading were holding Ipswich to a goalless draw but the East Anglian side then ran riot to win 4-0 courtesy of goals from Martyn Waghorn, Jordan Spence, Freddie Sears and Callum Connolly.
Meanwhile Wolves were held to a goalless draw by Sheffield Wednesday and it was the same story in the match between Nottingham Forest and Bristol City.
