Southampton moved up to fifth in the Championship table with a come-from-behind win that leaves Derby County in danger of missing out on the play-offs.
Carlton Morris ghosted in unchecked at the back post to guide home the opener for Derby after Joe Ward’s corner was unwittingly directed into the forward’s path by Southampton’s Caspar Jander.
Leo Scienza levelled with a brilliantly curled effort just after the hour mark and Taylor Harwood-Bellis competed the turnaround with a powerful header from a pinpoint Ryan Manning cross.
Victory lifted Saints five points clear of seventh-placed Wrexham, who face Birmingham City on Sunday, while the Rams are a further point and place adrift of the Welsh side with four games remaining.
