However, I should note that his PrOPS is based on his limited play in the majors, just 102 PA, not on his minor league stats.  

I don't really understand the math of MLEs, just that Bill James uses them and many other do too, and I was only familiar with this site's MLEs.  Here is a link to his methodology, perhaps you can tell me since you seem to be more familiar with them:  http://www.minorleaguesplits.com/mle.html

But let's put it this way, Sackmann is one of the analysts used to write in Graphical Player, he writes for The Hardball Times regularly (which is associated with Bill James), and runs a sabermetric site called BeyondTheBoxscore.com, which is affiliated with McCovey Chronicles via SB Nation, the link is to the right.  So I think the pedigree looks pretty good.

About your MLB 2B average, that includes all 2B, bad and good.  If you take all the qualifiers for the batting title, i.e. only starting 2Bmen, these regularly starting 2B have a collective batting line of .285/.340/.434/.764, which is 40-50 points higher than even the estimated OPS that you provided.  That would put his OPS+ at 93-94.  

Now lets take the ranks, to show how bad that really is.  If he was 724 OPS, he would rank 20th out of 24.  If he was 709 OPS, he would rank 22nd out of 24.  If he was the 694 OPS, he would be 23rd out of 24.  So even optimistically, using your numbers, he's a borderline replacement player, which is all that I and others are saying, that there is still doubt that he's a regular 2B.  

I am not saying that he won't make it but that there are plenty of evidence out there that says there are question marks about his ability to make it in the majors.  I'm encouraged that he has hit at every level plus he started taking walks, but as any of the MLEs show, what he has hit is not that big an accomplishment, as nice as it has been, the leap in talent from the minors to the majors is that large a chasm.

All I'm saying is that he needs to develop more if he wants to be a starting 2B in the MLB, because there are question marks about his abilities, question marks about his performance.  It is not just sabermetrics, but scouts have been saying this for a while as well.  

He has some encouraging signs, though, now he has to deliver and continue to improve. I'm rooting for him, but I think that realistically, he's not there yet.  I hope that he improves himself and prove to be worthy of becoming a major league starter.

Also, my usage of Feliz was only intended to show how much stats can fall when a player can move from AAA to the majors.  A .300 hitting AAA player can suddenly find himself hitting .250-.270 in the majors, and that takes up to 100 points off your OPS just from that, plus the reduction in SLG that will occur as well.  

Also, it doesn't help that for AA, AAA, and MLB, Frandsen's BB/SO ratio is 21/63, which is only 33%, which is even worse than Travis Ishikawa, who right now profiles as a low average hitter.  Hitters who have a better chance of hitting in the majors tend to have a minimum of 50% and ideally 100% if you want to be a good hitter.  Not that you can't do it with 33% but it is that much harder to do it, historically.  Who knows, maybe Frandsen is the exception to the rule.

I mean, he saved the world more than once, and none of us would have given the stupid animal talking jerk a second thought in hell if we even wanted just to save an otter.

But, more importantly, never underestimate FIRE. I'd take fire over heart any day. Seriously.

However, I think that if Klesko is truly back to his old self of 2-3 years ago as Bochy thinks he is, that is too good to keep on the bench.  Then he would start platooning at 1B with Aurilia, and when Aurilia is not playing 1B, he and Feliz will be battling for 3B against RHP (except on the days Bonds rest and Klesko plays LF).  Also, if Bonds is resting and Klesko hitting, we might see situations where Bochy is choosing between Frandsen, Linden and Feliz, because Klesko can play LF/1B and Aurilia can play 1B/3B.

I expect to see Vizquel to get more rest this year from Bochy, with Frandsen getting to start in his place, plus you know Durham's going to miss a bunch of games (that's partly why that simulation has the Giants winning the NL West, it had Durham getting 700 PA!), at least 20, so that's probably about 30 starts Frandsen gets plus he see some time pinch hitting.  So about 150-175 total PA.  More if Bochy decides to let Frandsen play 3B instead of Feliz (which will happen often if Feliz hit .202/.248/.348/.596 like he did in the second half of 2006).

Bench right now looks like Sweeney as Go-To PH, Klesko/Aurilia/Feliz (whoever sits), Alfonzo, Frandsen, Linden, assuming the Giants go with 13 position players and 12 pitchers.  Obviously, though, whoever is hitting is going to be getting the starts, so Feliz better not have another bad streak like that or he'll be sitting the pine for a long time.
