Beginnings Mayfield began racing in his hometown of
Owensboro, Kentucky, racing
BMX bicycles. He then proceeded to race
go-karts at local
Short tracks; moving to
Nashville Speedway USA at the age of nineteen. He soon went to work for
Sadler Brothers Racing as a
fabricator, and became their driver, winning Late Model Rookie of the Year at
Kentucky Motor Speedway in 1987. In 1993, Mayfield joined the
ARCA series, and was named Rookie of the Year.
NASCAR Mayfield made his Cup debut in the
1993 Mello Yello 500; starting 30th and finishing 29th in the No. 95 Earl Sadler-owned
Ford Thunderbird. In
1994, Mayfield declared he would run for
NASCAR Winston Cup Series Rookie of the Year, and signed to drive the Sadler Brothers' No. 95 Ford. He resumed his role as that team's sheetmetal man in 1995, and signed to drive the No. 02 for T.W. Taylor, for four races before completing the year in the No. 98
Fingerhut Ford for
Cale Yarborough. He ran twenty starts in his inaugural season, his best finish a nineteenth at
Rockingham. In
1995, he stayed with Yarborough full-time, and had an eighth-place run at the
Miller Genuine Draft 500, with a 31st-place finish in the points standings after qualifying for 27 out of 31 races. The next season, he had two top-fives and earned his first career pole at the
DieHard 500 Later that season, he and
John Andretti of the No. 37 Ford owned by
Michael Kranefuss and
Carl Haas, negotiated to begin their next year's contracts (in each other's then rides) early. Mayfield ended the year 26th in points. Mayfield formally joined the Kranefuss-Haas team in
1997. He had eight top-tens, including two 5th-place runs, and finished a then career-high 13th place in points. After the season, Carl Haas' interests in the team were sold to
Penske Racing South, and the team's identity was changed, with a new number (No. 12). Mayfield took the points lead early in the season, and won his first career race at the
Pocono 500. At the end of the season, he ranked a career best seventh in the point standings, with one win, twelve top-five finishes, sixteen top-ten finishes, and one pole. In
1999, he dropped four spots in the standings, despite twelve top-tens. In
2000, he won four poles and two races. Mayfield's third Cup series win and his second of 2000 is probably the most famous of all his wins, as he bumped
Dale Earnhardt out of the lead in the last turn and then used Earnhardt's famous "Rattle his cage" line against Earnhardt in victory lane. One of the poles, however, was at the
DieHard 500, and the car was found to have violated the rules and penalties resulted in the team earning -25 points from the race (his 126 points, earned by finishing fourteenth and leading a lap, were offset by the 151-point penalty NASCAR handed down). Later, while practicing for the
Brickyard 400, he crashed hard into the wall. He suffered a
concussion and was forced to miss the next two races. He finished 24th in points that season as a result of also having 11 DNF's (including six in a row). Mayfield began
2001 with two consecutive third-place finishes, but was released after the
Protection One 400. Rumors circulated around the garage that he had burned bridges with
Roger Penske in order to sign a new deal with
Ray Evernham's team.
Rusty Wallace added the next year, that he did not see head to head with Jeremy Mayfield as teammates and that they feuded several times. He later provided Jeremy Mayfield with a driving contract in Wallace's lower-tier team in 2005 as a sign of his regret. In
2002, Mayfield signed to
Evernham Motorsports, replacing
Casey Atwood. In his first year, Mayfield had four top-tens and finished 26th in points. He improved in
2003, winning the pole at the
Aaron's 499 and posting twelve top-tens, finishing nineteenth in points. In
2004, Mayfield returned to victory lane at the
Chevy Rock and Roll 400 to move his team into the ninth spot in the inaugural
Chase for the Cup, and finished tenth in points. For a while, winning a race to get into the Chase was referred by the moniker "pulling a Jeremy Mayfield." In
2005, he won the
GFS Marketplace 400, and finished ninth in the standings. In August 2006 he was released from Evernham
(see below). Evernham used
Bill Elliott and then
Elliott Sadler for the remainder of the season. Mayfield signed a contract with
Bill Davis Racing for
2007, driving the No. 36
Toyota Camry. He ran a total of 13 races for Bill Davis Racing in 32 attempts with a best finish of 22nd at
Kansas Speedway. In August 2007, it was announced that Mayfield and Davis would part ways at the end of the season. Later in the season, Mayfield would take over driving the No. 66 car for
Haas CNC Racing (then wholly owned by Gene Haas, no relation to Carl Haas, above) starting with Atlanta 2007. Late in 2007, he and teammate
Scott Riggs would switch rides putting Mayfield in the No. 70 car (later to become the Stewart-Haas No. 14 car) at the beginning the 2008 season. Mayfield completed seven races in the No. 70 with a best finish of sixteenth before he was released from the team. After July 9, 2008, Tony Stewart was able to announce his purchase into the Haas CNC team and the lineup of drivers to replace Riggs and Mayfield. Mayfield would complete one additional race at Dover in the No. 40 Dodge, filling in for the injured
Dario Franchitti. He would start tenth and finish 25th. After failing to get a ride for the 2009 season, on January 19, 2009, Mayfield and his wife announced that he started his own team, Mayfield Motorsports. Mayfield would attempt the full season in a self-owned Toyota, using the number 41 (the number and owner points was purchased from
Chip Ganassi Racing) and borrowing the Evernham-style of numbering. He raced his way into the Daytona 500 successfully. After ten races in the 2009 season, Mayfield qualified for just five. He was then embroiled in a
substance abuse dispute that, for all intents and purposes, ended his NASCAR career. By July 2009, Mayfield had sold his race team and operations due to lack of sponsorship, and all members of the race team either resigned or were laid off. During his NASCAR career, Mayfield had 36 career
Busch Series starts. He had five top-tens, his best finish being a 4th at Rockingham in
2003. He also had three
Craftsman Truck Series starts, with a best finish of sixth at the
2003 Hardee's 200 for
Green Light Racing. After his release from Evernham in 2006, he drove for
Billy Ballew Motorsports in a pair of truck races. ==Life after NASCAR==
