Yeah. Jim's apparently developed a really good relationship with people at the Complex. I'll probably have to amend some signing dates - the formal mlb.com listings will show whatever dates the contracts became "official," which seems to require review and approval in New York. But Jim routinely has these names before the official announcements (sometimes weeks before!) - and the same is true of stateside transactions.
And there are other games the official sites play. Example: Chris Micheles is listed as having signed on 6/18 - but that listing was added to the mlb.com transactions page within the last day - it wasn't there on Monday. mlb.com didn't list the signing until the Phils assigned Micheles to a roster - which was yesterday - and then they went back and posted the signing in last month's transactions. Erik Miller, Marcus Lee Sang, Jadiel Sanchez, Thomas Little, and Cam Beauchamp are still not "officially" signed, in that the official transactions page does not list their signings - even though we have mlb writers (Callis/Mayo) confirmations on three of them, and eyewitness sightings/conversations with them on a couple. No way to run an airline, IMHO, but I'm just a fan...
