It's never bad to add more good pitchers, but that is not really a high need area.
The Astros have Paredes (huge need) and two decent LH'd RP'ers (King & Sousa)- another high need area. Some think we need catcher depth, and the Astros have a great catcher, who they will not trade, but they have a good catcher prospect in Janek. They also have a RH'd RP'er in Abreu on his last arb year at $5.8M.
HOU may be looking to get under the tax line, so Paredes for Duran saves them $1.5M and Abreu makes it $7.3M saved. (King & Sousa are pre-arb.)
Duran for Paredes, Abreu and one from King, Sousa or Jankek? I think that gets HOU under the tax line and the star OF'er they seek.
We add some offense and fill our infield need. We lose a year, as Duran has 3, while Paredes 2, but add Abreu's one year and it's even before looking at the third piece. If HOU is interested, we could add DHam, Sogard, Eaton or maybe even Sandlin or Mullins types, but it looks like we are already overpaying, so maybe not.
