Dave Cameron brought up this subject at FanGraphs, and I've been wondering about it quite a bit. If anyone has a clue, please let me know.
↵He already has a great breakdown on the subject, so click the link. What I have felt the Giants will probably do is upgrade their outfield defense with Nate Schierholtz and put Pat Burrell at DH. That's probably the best option for them, but I didn't know Burrell doesn't like DHing. Frankly, if that's the best option, I hope that's true and Burrell stays in the field. On top of that, Cameron suggests it might be Aaron Rowand instead of Schierholtz.
↵Cameron points out the Pablo Sandoval situation might not be a good one as the Rangers could pitch three lefties in Arlington. I doubt that will be the case, but they may still see lefties half the time in those games, and the right side is Sandoval's week side.
↵The third option of putting Travis Ishikawa at first and DHing Aubrey Huff may well hurt the Giants. Huff's no fancy fielder, but putting Ishikawa's week bat in the lineup almost certainly does not make it worth it.
↵In any case, the Giants have difficulties with every DH move, and this is part of why the AL dominates interleague: NL teams don't spend money on a ninth guy paid to hit every day. The Giants do have lots of options, but two don't pose significant gains compared to the Rangers getting to play David Murphy and Jeff Francoeur while keeping Vladimir Guerrero out of the field. The one that does pose a good advantage, meanwhile, apparently runs the risk of upsetting a key player.
↵I just want to know what's going to happen, though, so I can know what to expect. My hunch is we won't know until the NL games are over, and it may well be a different guy at DH all three games.
