Portugal put on the most dominant performance of the World Cup, routing North Korea 7-0 on Monday in Cape Town.
Simao Sabrosa, Hugo Almeida and Tiago scored over an eight-minute span in the second half, after Raul Meireles' 29th-minute goal gave Portugal the lead. Liedson added another in the 81st.
Cristiano Ronaldo ended his goalless streak in the 87th minute, and Tiago added his second goal two minutes later. Ronaldo had not scored for his nation in a non-friendly match since the 2008 European Championship.
After a defensive blunder, the ball skidded free and suddenly looped onto Ronaldo's neck and over his head as he ran toward goal. The ball then luckily dropped right into his path for a tap-in and his breakthrough goal.
Ronaldo won FIFA Man of the Match but gave the award to Tiago, with Portugal coach Carlos Quieroz saying: "I thought (Tiago) should have won. Cristiano actually handed over the prize because he also felt Tiago was more deserving of it."
The win moved Portugal into second place in Group G with four points, two behind Brazil.
Chile 1, Switzerland 0: In Port Elizabeth, substitute Mark Gonzalez scored on a header in the 75th minute as Chile moved closer to a spot in the final 16.
Gonzalez headed home a pass from fellow sub Esteban Paredes, who had gotten around the staunch Swiss defense and crossed to Gonzalez at the back post. Gonzalez's downward header beat Diego Benaglio.
Before Chile scored, Switzerland set a World Cup record in the 69th minute by going 551 minutes without allowing a goal, breaking the mark of 550 held by Italy at the 1986 and 1990 tourneys. Chile has won both its games in Group H for six points. Switzerland and Spain each have three.
Switzerland played a man down when midfielder Valon Behrami was sent off with a straight red card for rough play in the 31st minute.
Spain 2, Honduras 0: David Villa scored both goals as Spain got back on track in Johannesburg. Villa beat three defenders in the 17th minute before goalkeeper Noel Valladares got a touch to the Spain striker's rising shot but not enough to keep it out.
Villa scored his 40th international goal in the 51st minute.
"We didn't play a good game," Spain coach Vicente Del Bosque said. "We had a lot of chances and should have won by more goals. There were touches of quality but overall we were vulnerable."
