One game in particular was cited for putting Sandberg (as well as the 1984 Cubs in general) "on the map", an NBC national telecast of a Cardinals–Cubs game on June 23, 1984. The Cubs had been playing well throughout the season's first few months, but as a team unaccustomed to winning, they had not yet become a serious contender in the eyes of most baseball fans. As for Sandberg, he had played two full seasons in the major leagues, and while he had shown himself to be a top-fielding second baseman and fast on the basepaths (over 30 stolen bases both seasons), his .260-ish batting average and single-digit home run production were respectable for his position but not especially noteworthy, and Sandberg was not talked about outside Chicago. The Game of the Week, however, put the sleeper Cubs on the national stage against their regional rival, the St. Louis Cardinals. Both teams were well-established franchises with strong fan bases outside the Chicago and St. Louis areas. In the ninth inning, the Cubs trailed 9–8, and faced the premier relief pitcher of the time, Bruce Sutter. Sutter was at the forefront of the emergence of the closer in the late 1970s and early 1980s and was especially dominant in 1984, saving 45 games. However, in the ninth inning, Sandberg, not yet known for his power, slugged a home run to left field against the Cardinals' ace closer. Despite this dramatic act, the Cardinals scored two runs in the top of the tenth. Sandberg came up again in the tenth inning, facing a determined Sutter with one man on base. As Cubs' radio announcer Harry Caray described it: "There's a drive, way back! Might be outta here! It is! It is! He did it again! He did it again! The game is tied! The game is tied! Holy Cow! Listen to this crowd, everybody's gone bananas! What would the odds be if I told you that twice Sandberg would hit home runs off Bruce Sutter?" The Cubs went on to win in the 11th inning. The Cardinals' Willie McGee, who hit for the cycle, h
Bob Dernier led off the game for the Cubs with a homer, and things went steadily downhill for the Padres as Chicago romped to a crushing 13–0 win in their first postseason game since 1945. Gary Matthews also homered in the first and added a three-run shot in Chicago's six-run fifth. Even starting pitcher Rick Sutcliffe went deep, while holding the hapless Padres to two hits over seven strong innings. The Cubs' overwhelming victory had Chicago's long-suffering fans dreaming of the franchise's first World Series championship since 1908.
Giving the Giants a dose of their own Game 1 medicine, the Cubs ended Game 2 early with a six-run first inning, five of the runs coming against Giants starter and loser Rick Reuschel. After Mike Bielecki picked Butler off first and retired the side, the Cubs went to work. Jerome Walton singled and scored on Ryne Sandberg's triple. After Dwight Smith lined out to first, Mark Grace doubled Sandberg home. Reuschel struck out Andre Dawson, but Luis Salazar singled to score Grace and moved to second on a single by Shawon Dunston. The Giants walked Joe Girardi to get to the pitcher's spot, and Bielecki responded with a single that scored Salazar and Dunston to make it 5–0. Walton again singled, scoring Girardi, and when Kelly Downs retired Sandberg on a pop-up, the Cubs went back into the field with a 6–0 lead. The game was essentially over after the first inning. The Giants cut the lead to 6–2 in the fourth when Will Clark singled and Kevin Mitchell homered for the second time in the series. But the Cubs got those runs plus another back in the sixth when Grace doubled with the bases loaded, scoring all three runners and giving the Cubs a 9–2 lead. The Giants got three cosmetic runs when Williams homered in the eighth and Robby Thompson homered in the ninth. But the Cubs' early scoring made it one game apiece as the series headed to San Francisco for Game 3.
Wood made his first appearance in the Major Leagues on April 12, 1998. In his fifth career start, on May 6, he threw a one-hit, no walk, 20-strikeout shutout against the Houston Astros in Wrigley Field, tying Roger Clemens' record for strikeouts in a nine-inning game and breaking Bill Gullickson's single-game rookie record of 18 strikeouts in 1980. Wood allowed only two baserunners: Ricky Gutiérrez on an infield single and Craig Biggio who was hit by a pitch with a count of two strikes and one ball. (Biggio had led the league in that category each of the previous three years.) Only seven balls reached fair territory. Five were grounders that never left the infield (including Gutierrez's hit), one was a short fly along the right field line, and another was a fly to center. A foul pop was caught by first baseman Mark Grace and the remaining twenty putouts were credited to catcher Sandy Martínez, who caught the entire game. Wood had no special advantages – the Astros went on to lead the league in on-base-percentage, and all of the regulars were in the lineup, including the four who finished the season batting over 300. Not surprisingly, the performance garnered a game score of 105 – the highest number ever calculated for a pitcher in a nine-inning game.
After years as a respected power/speed threat with a rocket arm in right field, he emerged during the 1998 season as one of baseball's greatest. It was in this season that both Sosa and Mark McGwire were involved in the "home run record chase", when both players' prowess for hitting home runs drew national attention as they attempted to pass Roger Maris' single season home run mark of 61 home runs that had stood since 1961. For the early months of the year, Sosa trailed McGwire significantly, being as many as 16 homers behind at one point in May. But as the chase progressed, Sosa would rally and eventually tie McGwire with 46 home runs each on August 10, after a couple months of straggling within a few homers for the lead. However, the moment was short lived as McGwire would pull away slightly and reach 62 home runs to break the record first on September 8, but once again Sosa would excitingly heat up the race by tying McGwire once again at 62 on September 13. Eleven days later, with two games left to play in the season, the two were tied at 66 home runs each. Sosa would end the season with 66 after playing both games without a home run(still a team record), just behind McGwire's 70 after hitting two home runs in each of the last two games. However, Sammy had become the first Major League batter ever to hit 66 home runs in a season. It was during that season, that Cubs announcer Chip Caray nicknamed him "Slammin' Sammy", a nickname that quickly spread. In addition, Sammy produced then career highs in batting average and slugging percentage, at .308 and .647 respectively. Sosa also led the league in RBIs and runs scored.
Maddux calmly overcame a shaky start to become the 22nd major league pitcher to reach 300 victories, leading the Chicago Cubs over the San Francisco Giants 8-4. Maddux relied on guts, guile and his bullpen to win his 300th game because he never quite found the pinpoint control that has so defined his stellar career. "Obviously, to win 300 games, you've got to have a lot of help. I've played on a lot of good teams, and a lot of times, you're only as good as the guys behind you. Today was a good example," Maddux said. He is the first National Leaguer to accomplish the feat since Philadelphia's Steve Carlton in 1983. Roger Clemens was the last to do it on his fourth attempt for the New York Yankees on June 13, 2003.
Lee was traded to the Cubs for Hee-seop Choi. He hit .278 with 32 home runs and 98 RBIs in his first year with the Cubs. In 2005, Lee had a career first half of the season, with a MLB-leading .376 batting average, 72 RBIs, and a tie for the major league lead in home runs with 27. The Cubs had traded superstar Sammy Sosa, who had previously been one of their best hitters, before the 2005 season. Lee showed early on that he could more than compensate for the loss, and while Sosa had a disappointing 2005 season with the Baltimore Orioles, Lee had a career year. By midseason, he was among MLB's leaders in each of the triple crown categories: batting average, home runs, and RBIs. Lee hit his 200th career home run on August 28, 2005, off Florida Marlins starter Josh Beckett. He finished the year with a career-best 46 HR. His .335 batting average was the highest by a Cub since Bill Madlock's .339 in 1976 and made him the first Cub since Bill Buckner in 1980 to win a National League batting title. He also won the Gold Glove at first base that year.
