Draft and minor leagues Sandberg opted not to attend after being selected in the 20th round of the
1978 baseball amateur draft by the
Philadelphia Phillies. In 1978, at age 18, Sandberg began his professional career with the
Helena Phillies in the rookie-level
Pioneer League. In his first professional season, Sandberg played exclusively at shortstop and hit .311 with a .390 OBP, one home run, 15 stolen bases, and 23 runs batted in (RBIs) in 56 games. Among his teammates at Helena were
George Bell, a future MVP, and
Bob Dernier, who later formed the "Daily Double" with Sandberg in Chicago. The three advanced through the Phillies system as teammates. Playing shortstop in 1979, Sandberg played for the
Class A Spartanburg Phillies in the
Western Carolinas League. In 138 games, he hit .247 with seven triples, four home runs, 21 stolen bases, and 47 RBIs. The Phillies soon concluded that Sandberg was not a successor to Bowa at shortstop. While Sandberg had played both second and third base in the minor leagues, he was blocked from those positions by
Manny Trillo and
Mike Schmidt. He was traded along with Bowa to the Cubs for shortstop
Iván DeJesús prior to the season. The trade came about after negotiations for a new contract between Bowa and the Phillies broke down. Cubs general manager Dallas Green wanted a young prospect to go along with the aging Bowa. Green had been instrumental in the drafting of Sandberg in 1978, while working in the Phillies front office. The two remained close over the years. The trade is now considered one of the best (if not
the best) in recent Cubs history. At the same time, it is considered one of the worst trades in Phillies history.
Chicago Cubs (1982–1994, 1996–1997) 1982–1983 trophy, received by Sandberg The Cubs installed Sandberg as their third baseman, before shifting him to second base late in the season with the call-up of rookie third baseman
Pat Tabler. Despite never having played third base before, he made just 11 errors in 140 games, After the Cubs acquired veteran
Ron Cey following the 1982 season, they moved Sandberg to second base full-time.
1984 Sandberg emerged with a breakout season in , in which he batted .314 with 200 hits, 114 runs, 36 doubles, 19 triples, 19
home runs, and 84 RBIs. In 1984, Sandberg's runs and triples totals led the National League. The Cubs went on to lose in the
National League Championship Series, 3–2 to the
San Diego Padres. He was named the National League
Most Valuable Player after receiving 22 out of 24 first place votes, the first Cub to do so since
Ernie Banks' back-to-back honors in and , and the first for a second baseman since
Joe Morgan in .
The Sandberg Game In an
NBC national telecast of a
Cardinals–Cubs game on June 23, 1984, the Cubs trailed 9–8 in the ninth inning against future Hall of Fame closer
Bruce Sutter, who would save a league-leading 45 games that season. Sandberg slugged a solo home run to left field, tying the game. After the Cardinals scored two runs in the top of the 10th inning, Sandberg hit a two-run homer against Sutter in the 10th inning to again tie the game. Cubs radio announcer
Harry Caray described the home run: Following the home run, NBC play-by-play announcer

Dave Owen.
1985 In , Sandberg batted .305 with 26 home runs, 83 RBIs, 113 runs scored, and a career-high 54 stolen bases, joining the

1990 In , Sandberg led the National League in home runs with 40, becoming only the third second baseman to reach that mark;
Rogers Hornsby and
Davey Johnson hit 42, and no American League second baseman had reached 40 until

1990 MLB All-Star Game, which was held at
Wrigley Field, home of the Cubs. Sandberg won the
Home Run Derby with three home runs over the left-field bleachers. Not until the
Cincinnati Reds'
Todd Frazier in did another player win the Home Run Derby in his own home stadium.

Silver Slugger Award at second base with a .304 batting average, 26 home runs, 100 runs, and 87 RBIs.
1994 Sandberg, a notoriously slow early-season starter, found himself struggling even more so than usual early in the 1994 season. With his average at a career low .238 and having recorded only 53 hits in 57 games,
1996–1997 , 1996 Sandberg returned to the Chicago Cubs for the season, and re-signed with the Cubs for . In his final season on April 26, Sandberg hit his 267th home run to pass
Joe Morgan and set a new record for home runs by a second baseman. Sandberg's final game at Wrigley Field and final career hit were on September 21, 1997. Sandberg retired with a career batting average of .285, and a record 277 home runs as a second baseman; ==Post-playing career==
