1991 Season

The 1991 Season as seen through the Prism of Player Won-Lost Records

This article takes a look at the 1991 season as measured by Player won-lost records.

The Best of 1991

I calculate Player won-lost records two ways: pWins, which tie to team wins and eWins, which control for context and the ability of one's teammates. For players with more pWins than eWins, their Player wins contributed to more team wins than one might expect; for players with more eWins than pWins, just the opposite is true: their Player wins translated into fewer team wins than expected. Or more briefly: a player with more pWins than eWins was better in context, a player with more eWins than pWins was worse in context.

The top 10 players in pWins above Positional Average and Replacement Level were as follows.

I take a look at some of the most interesting players of 1991 at the end of this article.

1991 Postseason

The 1991 postseason saw two teams go from worst to first: the Atlanta Braves and the Minnesota Twins, who ended up meeting in one of the greatest World Series of all time, with five of seven games decided by one run, one in 12 innings, one in 11 innings, and another in 10 innings, the last two being elimination games won by the Twins in Games 6 and 7 to win their second World Championship.

Best of 1991 by Factor and Position

Next, let's look at the top players in various aspects of the game.
Best by Factor: Batting, Baserunning, Pitching, Fielding
There are four basic factors for which players earn Player won-lost records: Batting, Baserunning, Pitching, and Fielding. The top players in 1991 in wins over positional average (WOPA) by factor were as follows.

Noteworthy Players of 1991

NL MVP Race
The vote for National League MVP in 1991 was extremely close. Atlanta Braves third baseman Terry Pendleton edged out Pittsburgh Pirates left fielder Barry Bonds by two first-place votes (12-10) and 15 total points (274-259). Player won-lost records suggest that the voters probably got this one wrong. Moreover, per Player won-lost records, the second-best non-pitcher in the National League was probably not Terry Pendleton, but rather Chicago Cubs second baseman Ryne Sandberg, who, based on Player won-lost records, was unfairly ignored by MVP voters (finishing a distant 17th in voting). The next table compares the 1991 seasons of Bonds, Pendleton, and Sandberg.

Looking at the three of them in a context-neutral setting, their performances were fairly similar in value with Bonds's superior offense being at least somewhat offset by Pendleton and Sandberg playing more valuable positions (with all three fielding their positions very well). The decomposition of eWins over replacement level for the three of them is shown in the next table.

Within context, shifting to pWins, Barry Bonds takes an even more clear and decisive lead over both Pendleton and Sandberg in pWins over either positional average or replacement level. Barry Bonds had an excellent season overall, batting .292/.410/.514, an OPS of .924. Breaking his batting down by leverage, however, shows why his performance looks so much better in context: in high/medium/low leverage situations Bonds's OPS's in 1991 were 1.086/.927/.825, respectively. In contrast, Pendleton and Sandberg performed about the same across all situations, regardless of the context.

Top NL Pitcher: Tom Glavine
According to Player won-lost records, the NL Cy Young voters got their vote right in 1991. The 1991 season saw Tom Glavine double his number of traditional pitcher wins, from 10 to 20, while lowering his ERA by more than 1.7 runs per 9 innings, from 4.28 to 2.55. It was the first of many great seasons of what would become a Hall-of-Fame career.

Tom Glavine's career record, as measured by Player won-lost records, is presented in the next table.

AL MVP: Cal Ripken
The top player in major-league baseball in 1991, as measured by eWins over either positional average or replacement level, won the 1991 AL MVP award, Baltimore Orioles shortstop Cal Ripken.

This was Ripken's second MVP award, his first coming eight years earlier. Ironically, Ripken's best season, as measured by Player won-lost records, was a season in which he finished 27th in MVP voting, 1984.

The next table compares Ripken's 1983, 1984, and 1991 seasons, as measured by Player won-lost records.

Last Hurrahs
The 1991 season was not the final season for any players who have been elected to the Baseball Hall of Fame yet. It was, however, the final season for two players who were elected to Baseball Think Factory's Hall of Merit, Dwight Evans and Rick Reuschel.

The final table of this article compares the career records of Dwight Evans and Rick Reuschel, as measured by Player won-lost records.

Article last updated: December 22, 2019

Wins over positional average and replacement level are calculated using data only for the 1991 season. Positional averages for starting pitching and relief pitching are calculated using single-year data for all starting pitchers and all relief pitchers.

All articles are written so that they pull data directly from the most recent version of the Player won-lost database. Hence, any numbers cited within these articles should automatically incorporate the most recent update to Player won-lost records. In some cases, however, the accompanying text may have been written based on previous versions of Player won-lost records. I apologize if this results in non-sensical text in any cases.
