I agree that Byrd will likely be moved during the season. However, I think that how soon depends as much on how Brett Jackson does in Iowa than Byrd himself. Of course, if someone were to come to us with an offer, he'd probably be moved either way, and even if Jackson is struggling the Sappelt enthusiasts can get to see him in action. Teams looking for a mid season replacement or spare bat are a lot more likely to come inquiring about Byrd than Upton, Jones, or Ethier. This regime isn't the same as the old one. Service time and potential cutoff dates for Super 2 status are likely to play a more significant role for callups than the old Hendry standby "he's earned it." Unless his performance is just otherworldly, Brett Jackson is likely to spend most of the season marinating in AAA to minimize his future cost. There's no real reason to call him up early in a rebuilding season... just so long as he gets a couple months worth of at bats later in the season he'll be fine.
