The
MLS Cup is the post-season championship of
Major League Soccer (MLS), a professional club
soccer league based in the United States that began play in 1996. The league's
third season was contested by 12 teams organized into two conferences, each playing 32 matches during the regular season from April to September. Teams faced opponents from the same conference four times during the regular season and from outside their conference twice. The season was the first to be played during a
FIFA World Cup, necessitating a lighter schedule for two weeks in June. MLS continued to use the modified version of the sport's rules that it adopted for the 1996 season, including a
penalty shootout from to decide tied matches (for which the winners earned one point) and a
countdown clock that stopped during
dead plays. The top four teams from each conference qualified for the playoffs, which were organized into three rounds and played primarily in October. MLS Cup 1998 was contested by two-time defending champions
D.C. United of the
Eastern Conference and the
Chicago Fire, an
expansion team that finished second in the
Western Conference. Chicago was led by
Bob Bradley, former assistant to D.C. United head coach
Bruce Arena. The two teams met twice during the regular season, resulting in 3–1 and 4–1 victories for D.C. United.
Chicago Fire was hired as the first head coach of the Chicago Fire The Chicago Fire and
Miami Fusion were the first
expansion teams in MLS history, entering during the 1998 season and split between the Western and Eastern conferences, respectively. The two teams participated in the
expansion draft, where Chicago selected two players from the
Los Angeles Galaxy who were later traded back in exchange for goalkeeper
Jorge Campos and midfielder
Chris Armas. The league allocated several international players to the Fire, including the Polish trio of midfielder
Peter Nowak, striker
Jerzy Podbrożny, and forward
Roman Kosecki, who formed the "Eastern Bloc" alongside Czech midfielder
Luboš Kubík. The team won their first two games, against the Miami Fusion and
Tampa Bay Mutiny, but fell into a five-match losing streak that lasted until early May. The losing streak was worsened by a scoring drought, as the Fire went 272 minutes without a goal until scoring four during a match against the
Colorado Rapids that ended in a shootout defeat. Chicago's offensive pair of Nowak and Kosecki were also frequent targets of fouls, picking up injuries and suspensions during a loss to D.C. United in early May that elicited complaints from manager Bob Bradley over missed calls from the referee. The Fire broke their losing streak with a victory over the Tampa Bay Mutiny, which marked the beginning of an 11-match winning streak that set a new MLS record. The streak included consistent scoring from Nowak, who was named Player of the Month in May, and several shutouts from goalkeeper
Zach Thornton, who would be competing for the starting position with Campos. By the end of May, the team had risen to second place in the Western Conference standings behind the Los Angeles Galaxy, who they defeated twice. Chicago were unable to surpass the Galaxy in the standings, but were able to open a 18-point lead over the third-place
Dallas Burn by defeating them three times in a three-week period by early July. The winning streak ended with a loss to the
Columbus Crew in July, which was followed by five consecutive defeats that were mostly played away from home. Chicago were without several key players who picked up injuries, including Nowak with a sprained knee that sidelined him for seven matches. Chicago ultimately finished the regular season in second place with a 20–12 record, behind league-leading Los Angeles. For the team's performance in the regular season, four players were named to the
MLS Best XI, Bob Bradley earned
Coach of the Year, Thornton won
Goalkeeper of the Year, and Kubík was named
Defender of the Year. Chicago entered the playoffs without goalkeeper Jorge Campos, who had returned to
UNAM Pumas in Mexico, and faced Colorado in the Conference Semifinals. The first leg, played at
Soldier Field, was tied 1–1 at the end of regulation time with a penalty kick from Kubík in the 50th minute and a Rapids equalizer by
Waldir Sáenz in the 79th minute. The match was decided in a shootout that was won 3–2 by the Fire after a conversion by
Jesse Marsch in the sixth round. Chicago finished a two-game sweep of the series with a 1–0 victory at
Mile High Stadium in Denver during the second leg, taking the lead with another Kubík penalty kick and several saves by Thornton to keep the shutout. The Fire then played against the Galaxy in the Western Conference Final, which began with a 1–0 Chicago victory at the Rose Bowl that was decided by a late
header scored by Jesse Marsch off a free kick. The second leg was played in front of 32,744 fans at Chicago's
Soldier Field, setting a new league playoff record, and resulted in another series sweep as the Fire advanced to the MLS Cup final. The team took the lead in the 31st minute through a goal by Nowak, who finished a rebound off goalkeeper
Kevin Hartman, but
Danny Pena equalized six minutes later for the Galaxy.
D.C. United was named the league's
most valuable player for his 19 assists and 10 goals for D.C. United D.C. lost six members of their cup-winning roster in the 1997–98 offseason, including striker
Raúl Díaz Arce and midfielder
Ben Iroha to comply with
salary cap limitations and three players picked by Miami in the expansion draft. The team responded by signing college players
Carey Talley and
Ben Olsen, as well as veteran defender
Geoff Aunger and forward
A. J. Wood. Defender
Eddie Pope was also absent for the first weeks of the season after undergoing surgery to remove a
cyst in his foot. United later acquired forward
Roy Lassiter, a former
Golden Boot winner, in a trade with Tampa Bay for
Roy Wegerle. United opened their third season on the road to Miami, winning 2–0 but losing
Jaime Moreno to a red card suspension. The team won their next two matches to extend a winning streak that began in the 1997 playoffs, but lost in their fourth match against the
Columbus Crew. D.C. would then lose only two of their next nine matches as they took first place in the Eastern Conference, despite losing several starting players to injuries and suspensions for yellow card accumulation. Starting defender Eddie Pope, who had recovered from his injury, and midfielder
Jeff Agoos were called up to the
U.S. national team for the
1998 World Cup, departing from the team in mid-May and missing six matches. Without Pope and Agoos, manager Bruce Arena used several lineups with reserve players and different formations, but the team ended their home winning streak in June by losing to the Dallas Burn in a shootout after a 4–4 draw. During a three-match stretch in June, D.C. conceded 10 goals in the shootout loss against Dallas, a 4–3 shootout win against Columbus and a 3–1 loss to Colorado. and regained Agoos and Pope in July at the start of a nine-match winning streak that lasted two months. The team also hosted the
1998 CONCACAF Champions' Cup and became the first U.S. team to win the continental tournament. D.C. provided eight players and Arena for the
1998 MLS All-Star Game, which was contested by teams of American and international players from MLS. United also became the earliest team in MLS history to clinch a playoff berth, doing so on August 7 by winning 1–0 in Dallas. Following the end of the streak, the team lost Agoos, Pope, and playmaker
Marco Etcheverry to injuries but won three of its remaining four matches. United finished the regular season with a 24–8 record and 58 points, 13 ahead of the second-place Columbus. D.C. and Los Angeles set a league record with their 24 wins, but the Galaxy's fewer shootouts allowed them to clinch first in the overall standings. Etcheverry earned the league's
Most Valuable Player Award for his 19
assists and 10 goals, while Ben Olsen was named
Rookie of the Year. United faced the Miami Fusion in the Eastern Conference Semifinals but remained without Agoos, Pope, Etcheverry, and forward
Tony Sanneh, who was injured in the regular season finale. Arena also swapped out starting goalkeeper and league shutout leader
Scott Garlick for backup
Tom Presthus, who had a stronger record in shootouts. D.C. won 2–1 at home in the first leg of the series with a pair of goals in the first half from Roy Lassiter and Jamie Moreno while successfully suppressing the Miami offense. The second leg in Miami ended scoreless in regulation time after Lassiter was ejected in the third minute and several shots hit the crossbar. United won 2–2 in the shootout to advance, with two saves from Presthus to allow Agoos to score the winning penalty in the fifth round. The Eastern Conference Final paired D.C. United against the Columbus Crew, who had defeated the
MetroStars to set up a rematch of the previous year's conference final. United hosted the Crew in the first leg and won 2–0 with a pair of second-half goals from Sanneh and Etcheverry to complement a strong defensive performance that shut out league scoring leaders
Stern John and
Brian McBride. The second leg marked the end of D.C.'s 13-match playoff winning streak after the team lost 4–2 to the home side on the narrow pitch at
Ohio Stadium in Columbus. The result was blamed on a poor defending that allowed the Crew to build a 3–0 lead in under 50 minutes that was later cut to one goal by Sanneh and Lassiter before a final goal for Columbus in the 81st minute. United clinched its third consecutive MLS Cup appearance through a 3–0 in the third leg, played again at home in Washington, D.C. The home team dominated possession and struck first with an Agoos goal in the 11th minute and followed up with a brace by Lassiter that culminated in converting an intercepted
backpass in the 79th minute.
