I am in a 12 team keeper league...
We each keep 6 players.
Please ignore this if it does not apply, but in many leagues (ESPN keepers, for example) it is possible to keep fewer than the standard number of players and have "pre-round" picks before the main draft starts. Many GMs seem to be unaware of this. At any rate, I would throw back the 6th keeper in favor of a "pre-draft" pick if that is an option.
If it's not an option, I vote for Pence. V-Mart is dead to me.
The hitting categories are:
H/AB, R, HR, RBI, SB, BB, K, TB, and AVG
I am somewhat confused about something - isn't hits/at-bats the same as batting average? You seem to have this category listed twice. Ignoring that, you're in a total bases league, which somewhat favors (relative to "normal" fantasy rankings) speedy doubles hitters over lumbering home run hitters, both because the double (or triple) is counted as more than merely "a hit" and because more offensive categories make the homerun correspondingly less important. All of which should be taken into account...
Which is a long-winded way of saying I like Granderson here, or Votto if you're feeling punchy. In fact, I think Votto may be your best bet here, assuming you have a CI slot to fill. You're going to end up filling that CI slot with a 1B if you've got any sense, anyway, so there's no reason to shy away from making that 1B your first pick if he's the best guy on the board.
PS: every time you create a league with walks as its own category (not in a points format), Alfonso Soriano clubs a baby seal.
