I'm a Texas Rangers fan. This is a good year to be one. First place.
Interestingly enough, a lot of analysts think Oakland will pull away and win the division because of their starting pitching. There's only one problem with that: their bullpen stinks. Texas has a "servicible" rotation (translation: average, but not as stinky as years past) and a pretty good bullpen... and more offense than the A's. What this means is that Oakland will likely continue to build leads and then blow them in the late innings, meaning a 3-0 lead in the 7th inning will mean a 4-3 loss (the Octavio Dotel trade hasn't helped), while Texas will continue to keep the damage limited to 5 or 6 runs, and if they have a lead of, say, 8-6 in the 7th inning, it will generally hold up. I think Texas will hold on for the division title unless the wheels totally fall off.
I'm not too worried about the Angels as long as Bartolo Colon's ERA is almost as high as his weight. Vladimir Guerrero can only carry a team so far by himself.
