2016 Season

The 2016 Season as seen through the Prism of Player Won-Lost Records

As a resident of the North Side of Chicago for 27 years before moving to Maine two months ago (June 2019), the next season in my look through the seasons for which I have calculated Player won-lost records is especially memorable. This article takes a look at the 2016 season as measured by Player won-lost records.

The Best of 2016

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 2016 at the end of this article.

2016 Postseason


Books have been written about this postseason, so let's just jump right to the numbers. The top performers in the 2016 postseason, as measured by Player won-lost records, are shown in the table below.

Top postseason players by round were as follows.

2016 World Series
Player Team pWins pLosses Net Wins
Corey KluberCLE1.40.70.8
Jake ArrietaCHN0.90.40.5
Addison RussellCHN1.20.80.4
Anthony RizzoCHN1.00.50.4
Ben ZobristCHN1.20.80.4


Going into Game 7 of the World Series, the choice of who might be chosen as World Series MVP was an interesting contrast between the two teams. If the Indians won Game 7, that would have meant that the Indians won all three games started by Corey Kluber, who would have almost certainly been MVP barring something very strange - which then almost happened. In contrast, the Cubs seemed to have a dozen viable candidates and it seemed most likely to come down to who came up biggest in Game 7. And, indeed, the World Series MVP was given to the player who had the game-winning RBI in Game 7, Ben Zobrist. As measured by net Player won-lost records (pWins minus pLosses), Player won-lost records agrees that the most valuable player of Game 7 was Ben Zobrist, although the overall MVP of the World Series was Corey Kluber, in spite of his relatively poor Game 7 performance, and the top player for the Cubs was Jake Arrieta, who won Games 2 and 6.

Now, back to earlier playoff rounds.

Best of 2016 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 2016 in wins over positional average (WOPA) by factor were as follows.

Noteworthy Players of 2016

Mike Trout
The 2016 season was the fifth season in a row in which the pre-award discussion in the online sabermetric community focused in equal parts on how Mike Trout was clearly the best player in the American League and how Mike Trout was likely to be robbed of the American League MVP award. For the second time in those five seasons, these concerns were unfounded and Mike Trout won the MVP award. As the tables above show, Player won-lost records agreed with the MVP voters (and sabermetic fans): Mike Trout was clearly the best and most valuable player in the American League in 2016.

Just for fun, here's how Mike Trout compares to Mickey Mantle in context-neutral Player won-lost records (eWins) through age 24 (Trout's 2016 season).

Trout wasn't quite at Mantle's level but there's no shame in being "not quite Mickey Mantle". All Mantle did at age 24 was win a Triple Crown (.353/52/130).

Kris Bryant vs. Anthony Rizzo
The winner of the National League MVP in 2016 was Chicago Cubs third baseman Kris Bryant. Going back to the first four tables in this article, Bryant was the best player in the National League as measured by eWins over replacement level (eWORL) and the best NL non-pitcher as measured by eWins over positional average (eWOPA). Shifting to pWins, which tie to team wins, however, Bryant slips to second among NL non-pitchers in both pWOPA and pWORL. The player who beat him in both is his long-time teammate and good friend - and the man with whom Bryant teamed up to record the final out of the 2016 World Series - Cubs first baseman Anthony Rizzo.

The next table compares Bryant and Rizzo ("Bryzzo") both in and out of context.

Historic Relief Pitcher Seasons
Over the last five months of 2016, Zach Britton pitched in 58 games, of which he finished 54, winning 1 game and saving 41. Overall, over those five months, he pitched 57 innings and allowed ONE earned run, good for a 0.16 ERA. That translated into a pWin winning percentage of over 0.800 for the 2016 season.

As impressive as Britton was, Andrew Miller was almost as good: 10-1, 12 saves, 1.45 ERA in 74.1 IP.

It turns out that both Britton and Miller had historic 2016 seasons, as measured by Player won-lost records. The next table shows the top 10 seasons in pWin winning percentage for players with at least 2.0 pWins in a season for whom I have calculated Player won-lost records.

Zach Britton in 2016 was the first player with 2.0 or more pWins and a pWinning percentage over 0.800!

Noteworthy Retirements
Finally, the 2016 season was the final season in the careers of several noteworthy players. The two most significant players whose final season was 2016 were probably long-time AL East rivals Alex Rodriguez and David Ortiz. Several years ago, I wrote an article comparing Rodriguez's and Ortiz's 2005 seasons, when they finished first and second in American League MVP voting. Their careers, as measured by Player won-lost records, are compared in the next table.

In Memoriam: Jose Fernandez
Finally, one other noteworthy event of 2016 warrants mention. In addition to the retirements of several players at the end of long and illustrious careeers, 2016 was the final season for one player for a far more tragic reason. On September 25, 2016, Marlins pitcher Jose Fernandez died tragically at the age of 24. The next table presents Jose Fernandez's career as evaluated by Player won-lost records.

Pitcher careers are much harder to forecast than position player careers, especially very young pitchers. The next table shows the 10 players most similar to Jose Fernandez in career value through age 23 (2016 was Fernandez's "age-23" season even though he turned 24 shortly before his untimely death), as measured by Player won-lost records.

It's hard to say exactly what Jose Fernandez's career might have looked like had he lived longer. There are no Hall-of-Famers on that list (yet), but 5 of the 10 players won a combined 14 Cy Young awards. Of course, the greatest tragedy of Jose Fernandez's death was not what his major-league career might have looked like but what the rest of his life might have been.

Wins over positional average and replacement level are calculated using data only for the 2016 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.
