Back 21 years ago, the NL West won by the San Francisco Giants, who went 90-72 under the tutelage of fifth year manager Dusty Baker and the first year under who will eventually be a future Hall of Fame general manager, Brian Sabean.
However, that team had a run differential of -9.
For comparison, the Dodgers, who finished 2 games back of the Giants with a record of 88-74, had a run differential of +97 and the Rockies, who went 83-79, had a run differential of +15. The main reason behind this was their pitching. Shawn Estes was their ace and while he had a career year with a 19-5 record with a 3.18 ERA, the pitching staff as a whole gave up the third most runs in the National League.
The offense was not a problem as they had the likes of JT Snow, Jeff Kent, and Barry Bonds anchoring their offense, which was 4th in the NL in runs scored. The trio all had a minimum of 28 homers and 101 RBI a piece.
They bit the dust in the NLDS when they faced the then-named Florida Marlins, the Wild Card team, swept them en route to a World Series title in only their fifth year of existence.
