More on the possible destination change for Wandy Rodriguez in a minute, but first, an actual trade. Going to the Jays: Kelly Johnson. Going to the D'Backs: Aaron Hill and John McDonald (yes, as confirmed by the presence of McDonald, it's a blockbuster). I'd be surprised if this sparks a dramatic long-term turnaround for Johnson (who's hitting just .209/.287/.412 with 18 homers) or Hill (hitting .225 with six homers), but there is some potential for a change-of-scenery spike in production for both players. In other trade-related news, the Rockies successfully claimed Wandy Rodriguez from the Astros, giving them until Thursday at 1 p.m. ET to negotiate a deal. However, Troy Renck of the Denver Post reports that the Astros are looking for "significant pieces" in return for Rodriguez. Among the names that Renck discusses as possibilities to go to Houston are Christian Friedrich, Wilin Rosario and Hector Gomez. Rodriguez has a respectable 3.62 ERA, 1.33 WHIP and 27/8 K/BB ratio in six career starts (32 1/3 IP) at Coors Field, so there's hope that a deal to Colorado wouldn't affect him too adversely. Cole Hamels (shoulder) hit the DL on Tuesday, but the news is hardly grim on that front. Per beat writer Todd Zolecki, pitching coach Rich Dubee said that Hamels looked "absolutely fabulous" during a Tuesday bullpen, and the lefty is scheduled to return to the rotation on Monday. In less positive shoulder-related news, Tommy Hanson had his scheduled bullpen session canceled on Tuesday after throwing just nine pitches (and, according to the Braves TV crew, feeling pain) during his Monday session. The right-hander was scheduled to begin a rehab assignment on Saturday, but now that won't be happening. For the moment, it's unclear how significant of a setback this is.
