The Giants have played 38 games. If you take the current roster, and project WAR to 162 games, you get the following:
Name WAR/162 PA/162 Melky Cabrera 5.12 699 Gregor Blanco 3.84 320 Buster Posey 3.84 563 Pablo Sandoval 3.41 443 Angel Pagan 2.98 674 Brett Pill 1.28 252 Nate Schierholtz 1.28 367 Brandon Belt 0.85 341 Hector Sanchez 0.43 264 Brandon Crawford 0.43 486 Joaquin Arias 0.00 264 Aubrey Huff -0.43 196 Ryan Theriot -1.28 260 Manny Burriss -1.71 337
Yah, I know. it surprised me, too. If I had told you before the season started that the Giants would have 5 players on pace for 3 WAR seasons, you would have laughed at me, and then asked whether they had any top10 prospects left.
The good news is that both the Blanco and Sandoval projections are low because they've only played part-time so far. Sandoval, once he's back will be full time, and Blanco is full time going forward right now.
The bad news is that Pablo will probably come back and won't produce at the same level, Melky's due for regression, and Blanco is probably playing way over his head.
The good news is that Belt will probably improve. He's currently on pace for only .85 wins and 341 PA.
The bad news is he probably won't get playing time.
The good news is that Pill is taking his playing time and Pill is on pace for 1.3 WAR over 251 PA!
The bad news is that he's due for major regression.
The worse news is that Huff is on pace for -0.43 WAR and 200 PA.
The good news is that Huff isn't starting anymore.
The bad news is that probably won't prevent Bochy from making sure he reaches his 200 PA.
The worse news is that Manny is on pace for -1.7 WAR and 336 PA.
The good news is that Theriot will be back soon to take his PA.
The bad news is the Riot is on pace for -1.3 WAR and 260 PA.
The good news is that Crawford is better than both of them and above replacement level.
The bad news is Crawford is only barely above replacement: 0.43 WAR and 486 PA.
The good news is that his wOBA jumped from .229 in March to .281 in May.
The bad news is that probably isn't sustainable.
The good news is that we have Arias to replace him, if necessary.
The bad news is Arias is on pace for exactly 0 WAR.
PS> All WAR projections for the season should always be taken with a grain of salt. Nothing stays the same.
