Casares - American Anthony Kim will meet Ross Fisher of England in the final of the Volvo World Matchplay Championship after both players won their respective semi-finals on Saturday.
Kim defeated Australian Robert Allenby for the second time this month while Fisher emerged victoriously from a 39-hole marathon against Masters Tournament champion Angel Cabrera of Argentina.
Los Angeles native Kim secured a 5&4 victory over Allenby, whom he beat 5&3 at the Presidents Cup three weeks ago, and will now meet Fisher on Sunday.
In their scheduled 36-hole semi-final, Fisher went from 2-up to 1-down against Cabrera with five to play but came back into the match by winning the 32nd and 33rd holes.
He then paid the price for laying up at the par five last, where Cabrera made birdie from the rough to force a sudden death playoff.
In total the pair returned to the final tee three more times before Fisher hit a brilliant fairway wood to 12 feet.
Cabrera, who had bunkered and then hit over the green, then conceded defeat.
