The team is obviously not performing up to anyone's expectations, least of all mine. In the spirit of transparency I decided to take a look at the last AL West prediction post that I did and see where I've been off as we hit the first post. All numbers presented below are valid at the start of play yesterday.
If I just went with the actual hitting and fielding totals for the year, this would be a pretty boring exercise. Everyone aside from Ichiro and Franklin is hitting too poorly (though Friday certainly helped) to be living up to their projections. As I have mentioned a few times though, a good chunk of that poor performance may be attributable to awful luck.
I decided then, first for my own visual aid and now reproduced for yours, to table out each position as in the prediction post linked above. I used FanGraphs to gauge the actual value to date from each position, grouping where needed (left field, DH, SS). I then took the runs above replacement for each player/grouping and added back the runs lost due to "luck" or what have you as outlined in the regressing wOBA posts.
| Pos | Pred. Starter | Actual Starter | Predicted | Actual | Luck-adj | Diff from Pred |
|---|---|---|---|---|---|---|
| C | Rob Johnson | Rob Johnson | 1.0 | 0.9 | 2.4 | +1.4 |
| 1B | Casey Kotchman | Casey Kotchman | 1.5 | -0.9 | 2.0 | +0.5 |
| 2B | Chone Figgins* | Chone Figgins | 3.0 | -1.2 | 0.9 | -2.1 |
| 3B | Jose Lopez* | Jose Lopez | 2.0 | 0.8 | 2.7 | +0.7 |
| SS | Jack Wilson | Jack Wilson | 2.0 | 1.2 | 0.1 | -1.9 |
| LF | Ryan Langerhans | Milton Bradley | 1.5 | 0.5 | 1.4 | -0.1 |
| CF | Franklin Gutierrez | Franklin Gutierrez | 4.0 | 5.9 | 4.5 | +0.5 |
| RF | Ichiro Suzuki | Ichiro Suzuki | 4.0 | 4.6 | 4.8 | +0.8 |
| DH | Milton Bradley | Ken Griffey Jr. | 2.0 | -1.2 | 0.7 | -1.3 |
| Bch | N/A | N/A | 1.0 | -2.0 | -1.4 | -2.4 |
*I had Lopez at 2B and Figgins at 3B originally in the predictions, but for sake of readability have simply switched them here. It would not have affected any predictions back in February.
Commentary below the fold.

The total is just about 4 wins below my predicted values with the main culprits being Chone Figgins at second base, Jack Wilson at short and the bench. Keep in mind that Jack Wilson's entire deficit is erased if you substitute in DRS (6 runs saved) for UZR (-1.7 runs). Figgins is also three runs (or a full win over 162 games) lower in UZR than DRS. I'm not saying DRS is better, but am pointing it out to illustrate how small some of these margins are.
Four wins is a lot, but I also pegged the Mariners, rather optimistically it seems, at 88.5 wins at the time of the predictions used. Granted, that was before the Cliff Lee injury, the Mike Sweeney decision and so forth. All of those would have had me downgrading those totals if I had bothered to run another prediction before the start of the season. Still, though this is only one half of the story (I will do pitchers at some point), I find it yet another example that while the 2010 Mariners have played nowhere near how we dreamed, they have not played as poorly as their record suggests.

While the M's haven't played as poorly as their record suggests...
Haven’t they also not played as well as some of their stats suggest? How many runs have been lost by poor decision making, especially on the base paths. There have been some absolutely atrocious plays that aren’t reflected in the stats; Junior trying to score from first, Johnson getting thrown out at third, every time Brumley has waived someone in only to get thrown out by a mile and a half.

I agree, sure seems like we could have won some of these 1 run games,
with better managerial decisions.

Rob Johnson's numbers are extremely hard to swallow.
Hard to equate with reality, that is. Is FanGraphs really unable to evaluate catcher defense to such a degree?

It only uses rSB, which is Fielding Bible's metric for stolen base runs saved.

Thank you

Rob Johnson's getting away with murder.
Most of his passed balls are being called wild pitches.

This team has certainly had awful luck
But it seems like this team is doing everything in its power to turn the law of averages into a theory.

Don't things have to remain relatively unchanged for things to "average out"?
At the risk of sounding overly snarky, if your lineup is changing and some guys are getting played in odd positions or at odd times or aren’t getting enough playing time, then their luck can’t average out – you have additional factors affecting the odds.
On a slightly more serious note, all statistics is based in theory. Even the “law” of averages doesn’t guarantee that you’ll have close to 50% heads after a million coin-flips! …Although I’m frustrated enough with Wak to begin referring to him as a “lawbreaker”.
