It's still possible to trade for relief help in August, as we've seen Matt Lindstrom, Jose Mijares, Pat Neshek, and Mike Gonzalez moved in the last few years. Some trade candidates to consider this month, listed by team:
- Blue Jays: Darren Oliver (L)
- Twins: Brian Duensing (L)
- White Sox: Matt Lindstrom (R)
- Mariners: Oliver Perez (L)
- Angels: Joe Blanton (R)
- Astros: Wesley Wright (L), Travis Blackley (L)
- Phillies: Jonathan Papelbon (R)
- Mets: David Aardsma (R), Scott Atchison (R), Pedro Feliciano (L), LaTroy Hawkins (R)
- Marlins: Chad Qualls (R), Ryan Webb (R)
- Cubs: Kevin Gregg (R), Matt Guerrier (R), James Russell (L)
- Brewers: John Axford (R), Burke Badenhop (R), Mike Gonzalez (L)
- Padres: Huston Street (R), Tim Stauffer (R)
- Rockies: Matt Belisle (R), Manny Corpas (R), Wilton Lopez (R), Josh Outman (L), Rafael Betancourt (R)
- Giants: Javier Lopez (L)
Keep in mind that availability varies by player – the Padres may not be open to moving Street, even though he could clear waivers. Relievers who are under control cheaply beyond this year stand a good chance of being pulled back if claimed. Papelbon, the biggest name here, would clear waivers but would prove difficult to trade. I haven't listed relievers from the Yankees or Nationals in this post, but if those teams slip further, they could be willing to make a few deals later this month.
