Dave Parker’s WAR7 shows he had a good peak in his career
WAR7 is more favorable for Dave Parker, as his WAR7 (his WAR in his best seven seasons) is 37.3, or 31st among primary right fielders. Modern Hall of Famers Dave Winfield and Enos Slaughter are just ahead of Parker at 37.9 and 37.4. But the only modern HOF right fielder below him? Harold Baines.
With JAWS (which balances WAR and WAR7), Parker is at 38.7. That is 40th all-time. The only modern HOF right fielder below Parker? You guessed it: Harold Baines.
So why the discrepancy between the old school and new school? In a word: defense.
Prior to his injuries and most of his drug use in the 1980s, Parker was an excellent defender. When you look at Total Zone Runs (TZ or Rtot), which is the predecessor to Defensive Runs Saved (DRS), Parker was a great outfielder. From the start of his career through 1979, Parker had 42 TZ, or an average of 6 TZ per season.
But after that, he had -63 TZ, or an average of just under -6 TZ per season. That’s why, in 1986, he has such a big contrast. He came in 5th in NL MVP voting … but he had an rWAR of 0.3. It’s because he had -17 TZ.
