By Career WAR as a Met, looking mostly at every day players:

Player   Career WAR    Best Season

Strawberry  37.7      6.7

Wright         30.4      7.8

Alfonzo        29.1      7.0

Beltran        26.8      8.0

Hernandez 26.5      6.5

HoJo           24.7      7.7

Piazza         24.6      5.5

Reyes         21.8      5.9

Mookie       19.4      3.2

Olerud        18.6     8.1

Stearns      18.5     5.5

Cleon         17.6     7.6

Note - Bernard Gilkey ties Olerud for the best single season in terms of WAR by an every day player with 8.1 though Gilkey had a total of 11.1 WAR in 3 seasons.

Pitchers:  Seaver 75.8 (9.5); Koosman 41.8 (6.8); Gooden 41.2 (11.7); Matlack 27.0 (8.6); Leiter 26.3 (6.5).  Gooden had 3 seasons in his career with better than a 3.8 WAR, all before he was 22.


My take-away from this is that Wright is likely to pass Strawberry, Gooden and Koosman by this time in 2012.
