5 must-see matches from Brock Lesnar's first WWE run

#2 Brock Lesnar vs The Rock (WWE SummerSlam 2002)

Brock Lesnar's rookie WWE year is one of the most impressive first twelve months in WWE history.

The Beast won the 2002 King of The Ring tournament, earning him an opportunity for the WWE Undisputed Championship in the main event of SummerSlam that year against The Rock.

An incredible match saw Lesnar largely dominate The Great One, hitting The Rock with an F5 to capture the first WWE Championship of his career at the biggest event of the summer.

The title victory for Lesnar was historic for a variety of reasons. In winning the match, Brock Lesnar became the youngest WWE Champion in history at the age of 25. However, this record was broken two years later by Randy Orton at the very same event.

Brock Lesnar also became the second fastest superstar in WWE history to capture the WWE title after his debut at just 126 days.

#1 Brock Lesnar vs Eddie Guerrero (WWE No Way Out 2004)

Brock Lesnar participated in one of the greatest WWE Championship changes in company history when he was defeated by Eddie Guerrero at No Way Out in 2004.

The storyline heading into the match centered around Guerrero's past issues with substance abuse, addiction and his recovery into becoming one of the most beloved and popular superstars in WWE history.

Meanwhile, Lesnar had also begun a feud with RAW Superstar Goldberg that would culminate at WrestleMania XX.

The closing moments of the match saw the referee get knocked down. This allowed Goldberg to appear and spear his WrestleMania opponent. Eddie Guerrero capitalized by countering an F5 from Lesnar into a tornado DDT onto the WWE Championship belt.

Guerrero followed this with a frog splash to capture the first and only WWE Championship of his career in one of the greatest moments in WWE history.
