How Likely is Pence to Rangers?

The San Francisco Giants are listening to offers on Hunter Pence, according to Robert Murray of MLB Injury News (via Twitter). He also later tweeted that the Texas Rangers look like are making Pence their "number one hitting target."

From what I'm seeing, it looks like the #Rangers No. 1 hitting target is #SFGiants OF Hunter Pence. He is definitely possible right now.

With July 31 just four days away, how possible is this deal happening? The Rangers have many tradable prospects, and the Giants would like to fill some pitching holes (4.16 team ERA; 23rd in MLB). Luke Jackson and Connor Sadzeck seem like names to be watching in this trade, if the deal makes progress, and the Rangers are truly interested. 

Jackson is currently pitching in High-A, and has put up good numbers. He's 8-4 with a 2.39 ERA, and opponents only hit .211 against him. He's ranked ninth on the Rangers twenty top prospects. Sadzeck is currently pitching in A ball, and also has been very commanding. He's 9-3 with a 2.51 ERA, while opponents only hit .220 against him. He is ranked nineteenth. Both pitchers have a chance of flying through the Giants system, if traded. Although they are years away, the way they have been pitching almost makes it seem like they could be in the majors in 2-3 years. Exactly what the Giants would like. 

The deal is not even in an early stage, but could progress quite nicely if the Rangers and Giants find prospects that they'll agree on.

I believe that this deal could happen very, very quickly because the Giants have a hole in the pitching rotation, and the Rangers have some pretty nice pitching prospects. At this point and time, it's unknown exactly how far the Rangers are willing to go for Pence, and how much the Giants want in return. But, on paper, this seems like it could eventually happen.
