FORTALEZA, Brazil -- Georgios Samaras scored an injury-time penalty to put Greece into the second round of the World Cup with a 2-1 win over Ivory Coast.

Samaras was adjudged to have been brought down by substitute Giovanni Sio and Samaras calmly slotted in the spot kick for the win that puts Greece through to the knockout stage. Ivory Coast would have advanced with a draw.

Substitute Wilfried Bony had equalized for Ivory Coast in the 74th, beating goalkeeper Pangiotis Glykos from close range after being set up by Gervinho.

The Greeks had taken the lead just before halftime through substitute Andreas Samaris.

Veteran striker Didier Drogba started for Ivory Coast along with Yaya and Kolo Toure despite the recent death of their brother Ibrahim. The Ivorians wore black armbands as a sign of mourning.

Colombia eliminate Japan

Substitute James Rodriguez scored a brilliant goal and set up two more for Jackson Martinez as Colombia beat Japan 4-1 on Tuesday to confirm top spot in Group C and eliminate the Asian champions from the World Cup.

Already assured of advancing, Colombia guaranteed first place with its third straight win, setting up a second-round match against Uruguay.

The Colombians started with a virtual second-string lineup but still went in front when Juan Cuadrado -- one of the few regular starters -- drilled in a 17th-minute penalty.

Japan equalized with the last touch of the first half through Shinji Okazaki's header but Martinez scored in the 55th and 82nd minutes -- both from superb passes from Rodriguez -- to put the result beyond doubt.
