He also leads in most offensive categories - including nose hairs (couldn't resist).

Charlie Culberson is only 21 years old (DOB=4/10/89). The Giants saw enough progress in the 2B prospect that they decided to send him to the exclusive and prestigious AZ Fall League, along with Brandon Belt, Conor Gillaspie, and pitchers Jason Stoffel, Ryan Verdugo and Joe Paterson.  Culbie has surprised everybody by not only outperforming both of his older and higher-rated infield teammates (Belt and Gillaspie), but every other hitter in the league. He currently leads the league in:

batting average (.431), doubles (8), hits (25), Total Bases (43), SLG (.741), OPS (1.201), and Runs (15). 

He's also tied for 2nd in triples (2).

Despite being one of the younger players in the league, in 14 games and 58 AB he has hit:
.431/.459/.741/1.201 with ISO=.310, HR=2, TPL=2, DBL=8, K=16.1%, BB=4.8%, & SB=1/3

It's admittedly a very SSS, but at least it does provide some confrimation that the strides he made in SJ weren't totally just a "Cal League Effect" mirage. He's starting to create a buzz, and even national writers like Keith Law and Jason Grey have written about him in the past few days.  Everybody agrees he has a lot of work to do on his D, but the live bat could carry him a long way.

For those that aren't familiar with his back story, I'll summarize here.    He's a former 1S pick in the 2007 draft - out of high school in Calhoun, GA.  After back-to-back disappointing seasons in Augusta in 2008 & 09, this summer (his 3rd full season in the Giants farm system) he finally had a break-out offensive performance while playing for San Jose in the Cal League (A+).  He dramatically increased his power output and batting average, while also improving his K-rate significantly.  He ended up the season with a lingering thumb injury
that affected his power output over the last 6 weeks, but still was able to hit:
.290/.340/.457/.797 with HR=16, DBL=28, TPL=4, ISO=.167, K=18.3%, BB=6.1%, & SB=25/32
