England came out of the halftime on fire with two quick goals against Wales to take a 2-0 lead.

Marcus Rashford scored in the 50th minute on a beautiful free kick from just outside the box, followed by a goal from Phil Foden a minute later.

England advances to the second round with a win or draw. With a two-goal lead, they appear poised to earn the top spot in Group B.

The U.S. leads 1-0 against Iran at the half in a game they must win to advance to the knockout stage of the tournament.

Star striker Christian Pulisic scored the first goal of the game in the 38th minute on an assist from Sergiño Dest. Dest headed a ball to Pulisic, who was crashing into the box and knocked the ball into the bottom left corner of the net before crashing into Iran's goalkeeper.

The U.S. came very close to making it 2-0 in stoppage time of the first half when Timothy Weah beat the keeper one-on-one. However, Weah, who had scored the only goal in the tournament so far for the U.S., was called offside.

In the other Group B match, England and Wales remain tied at 0-0. England just needs a draw to advance to the knockout stage.

Christian Pulisic has knocked home a goal to give USA its first lead.

Pulisic, the team's biggest star, streaked to the net to knock one in from close range before crashing into Iran's goalkeeper. He remained down, in the net, before finally being helped off the field. After being checked out on the sidelines, he returned to the game.

The U.S. and Iran remain scoreless midway through the first half of a decisive Group B match in the World Cup, but the U.S. has had the majority of chances so far.

The U.S. had 60% of possession, four shots and two shots on goal in the first 30 minutes. Iran, meanwhile, has yet to attempt a shot.

England and Wales also remain in a 0-0 draw through 30 minutes.

Argentina, led by the legendary Lionel Messi, faces a critical match with Poland as it attempts to qualify for the knockout rounds Wednesday.

Group C is tightly packed with Poland standing at 4 points, Argentina at 3 points and underdog Saudi Arabia at 3 points. Mexico is at the bottom of the table with 1 point, but it does have a chance of making the next round.

If Poland or Argentina wins outright, it will qualify for the next round. If Saudi Arabia defeats Mexico, it will also improbably make it to the knockout stages. But who advances otherwise gets more complicated from there.

Mexico needs to defeat Saudi Arabia if it wants to advance, but they still would need to get a helpful result in the Poland-Argentina match (either a Poland win or a draw and advantageous goal differential). A draw in both matches would put Argentina and Saudi Arabia tied at 4 points and come down to goal differential as well. Poland would win the group.

Group D is more clear. France has already qualified for the next round, so they may take it easy against Tunisia. Tunisia would need to beat France, get a draw in Australia-Denmark and win out on goal differential.

The Aussies would advance with a win against Denmark. Denmark can only advance with a win, though it would need a better goal differential than Tunisia if the African country upsets France.

Here is Wednesday's schedule:
