The 2003 Season as seen through the Prism of Player Won-Lost Records



Next in my continuing series of looking at individual seasons through the prism of Player won-lost records is the 2003 season.

The Best of 2003

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.

Barry Bonds
The best player in major-league baseball in 2003 was also the best player in major-league baseball in 2001, 2002, and 2004, as well as several seasons in the late 20th century. Barry Bonds's 2001 - 2004 run was certainly one of the best statistical four-year runs in baseball history. It was not, however, the best such run, as measured by Player won-lost records.

The next table shows the top 5 4-year totals for pWins over replacement level.

Mark Prior
The best pitcher in major-league baseball in 2003, as measured by pWins over positional average and either pWins or eWins over replacement level, was Mark Prior. In 2003, Mark Prior pitched 211.1 innings with 245 strikeouts (2nd in the NL), against only 50 walks, with a 2.43 ERA (3rd in the NL), and a traditional won-lost record of 18-6. He was only 22 years old. The future looked limitless. Alas, Mark Prior would only win 18 more games in the rest of his career.

I actually wrote about the player most similar to Mark Prior through age 22 in my article about the 1976 season. As I said in that article, it's always a little bit depressing to do a comp list of young pitchers: the fact is, what happened to Mark Prior is, in many ways, the norm, not the exception, throughout baseball history.

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

2003 Postseason

I live 3 - 4 blocks from Wrigley Field. In about the fifth inning of Game 6 of the 2003 NLCS, my wife turned to me and said, "We should try to go to a World Series game." That opportunity has still not presented itself to us yet. That's all I'll say about the 2003 postseason, which was perhaps the most bittersweet postseason of my baseball fandom. I'll just let the Player won-lost records for the 2003 postseason speak for themselves.

Best of 2003 by Factor and Position

Next, let's look at the top players in (context-neutral, teammate-adjusted) eWins over Positional Average 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 2003 in eWOPA by factor were as follows.

Ichiro Suzuki7.24.42.8


Ichiro Suzuki's 2003 season was arguably the best fielding season for any season for which I have calculated Player won-lost records. The next table shows the top 10 seasons in fielding wins over replacement level.

Eddie R. Miller19439.17.11.6


Because I tie replacement level to positional average, replacement level has a built-in positional adjustment, so that fielding wins over replacement level should control for defensive position and these numbers should be (roughly) comparable across positions. Even so, comparing fielding numbers across positions is, at best, highly speculative.

That said, Ichiro's 2003 season is at the top of the list, which is pretty damn impressive.

Best by Position
Next, we look at 2003 Major-League leaders in eWOPA by position. The figures shown here only include Player decisions earned while playing this particular position, and include no contextual adjustments (expected or actual).

Relief Pitcher
eWins eLosses eWOPA
Eric Gagne5.22.31.3


For relief pitchers, context-neutral records may not be the best measure of how good they are, as context can matter a great deal, depending on how a pitcher is used. Here are the top relief pitchers of 2003 in context, in terms of pWins and pWOPA.

Top Relief Pitchers of 2003, based on pWORL

Brendan Donnelly6.72.80.7051.82.5
Tim Worrell8.14.80.6281.52.4


The way that I calculate pWins, the players on a team earn 2 pWins in every team win and 1 pWin in every team loss, so that, in some sense one-third of Player decisions are what I sometimes call "background wins" and one-third of Player decisions are "background losses". If one subtracts out "background wins" and "background losses", player pWins would sum to team wins and player pLosses sum to team losses. If I did not include these background wins and losses, then, anybody with a pWin winning percentage over 0.667 (two-thirds) would break the system: subtracting out "background losses" leaves Gagne, Foulke, Rivera, and Donnelly contributing negative losses. That's an extraordinary collection of high-quality pitching.

Noteworthy Players of 2003

Finally, let's take a look at some players who had noteworthy 2003 seasons.

Notable Debuts
Based on their careers to date, the two best players who made their major-league debuts in 2003 were Miguel Cabrera and Chase Utley. Their careers, as measured by Player won-lost records, are compared in the next table.

Cabrera's and Utley's careers are an interesting contrast. From 2005 - 2009, Utley was clearly better. But then, Utley, who is four years older than Cabrera, started to show his age, while Miguel Cabrera took his game to another level, so that Cabrera was clearly the better player from 2010 - 2013.

Last Hurrahs
Finally, 2003 was the final season for one of the most colorful - and greatest - players in major-league history, Rickey Henderson. The final table of this article presents Rickey Henderson's career, as measured by Player won-lost records.

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.
