Everton left it late but ended their 2017/18 home campaign by extending their unbeaten run to five matches.
Trailing to Nathan Redmond’s 56th-minute header, the Blues levelled with pretty much the last kick of the game as Tom Davies’ effort from the edge of the box deflected off defender Wesley Hoedt to wrong-foot goalkeeper Alex McCarthy.
By that point, Southampton had been reduced to 10 men, Maya Yoshida having collected his second yellow card with five minutes remaining.
With Wayne Rooney (knee), Theo Walcott (calf) and Dominic Calvert-Lewin (back) all ruled out through injury, and Gylfi Sigurdsson still not fit to return following a knee problem, manager Sam Allardyce had limited attacking options at his disposal.
