I have not been one clamoring for Elko immediately, but Dalbec over Elko is an interesting one. Neither really cover anything but 1B/DH. Both hit RH. I guess Dalbec could stand at 3B, but he's not going to over the other incumbent 3B options. Dalbec has been solid so far, but he's nearly 30. I guess perhaps Sox feel his 40 man spot will be easier to clear than Elko? That's about the only reason I can see for this decision. Unless Lee is really close and we will start seeing Quero at DH most days he's not catching, then there really aren't At bats for Elko at the moment.
