...up until the Tigers demanded they pick up 3/4 of Lowe's contract. It may still happen, if the Tigers will pick up this year's tab for Lowe (giving them the payroll space to add Beltran without the Mets picking up any of his salary, so they won't have to send a good prospect to the Mets and play against him for years), with the Braves picking up a good chunk of next years salary(which they can). but the Mets are trying to get prospects for Beltran, so this isn't likely. It will becomeVERY likely if Beltran is still around after the deadline and clears waivers (but he probably won't). The only problem here is the Braves won't want to pick up a good chunk of next years salary for Lowe for a 2-month rental.
I just don't see them doing anything other than picking up a right-handed version ofHinske and a RH reliever.
Their other problem is they have 7 quality MLB starters for next year, but 2 of them are gone after 2012 (Hudson and Lowe) and 2 will never be signed to extensions (Hanson and JJ). So if they trade a starter to clear up space for Minor and Teheran next year, then they are simultaneously creating a hole for 2013.
Relatedly, i think the best package they can offer is Minor and Vizcaino. Minor gives you a MLB ready starter, albeit without an ace ceiling. Vizcaino is a potential ace, but is a year away and a much greater risk (extensive injury history at only 20 years old, delivery conducive to injury, is generally considered a Tommy John surgery waiting to happen). Those two complement each other pretty well, and doesn't affect the Braves plans at all at this point (their first round pick they just signed is a Minor-clone). They just haven't found an available player worth that that fits their needs. In the offseason, they probably will.
Picking up a LF instead of a CF isn't really a problem. Between Chipper, Prado, and Heyward all struggling with their health, there will be plenty of playing time available. Even if all are active, you can rest each one day a week (plus Uggla), and sit McLouth/Schafer against lefties, and get the new guy 6 or 7 games a week.
I don't see Bourn happening. He's a leftie that doesn't hit lefties well, so he's really not enough of an improvement over Schafer (especially considering he makes million$ more)to be worth what the Astros will want.
