Heyman On Rockies, Wedge, Strasburg

The latest from SI.com's Jon Heyman…

• Heyman says Rockies manager Clint Hurdle "appears to be on the firing line" after the team's 12-18 start.  GM Dan O'Dowd called the speculation "unfair at this time," talking to Troy E. Renck of the Denver Post.  O'Dowd's job seems safe and he could direct a "July tradeoff."  Heyman speculates on Garrett Atkins and Huston Street as candidates.  Heyman doesn't mention them, but Brad Hawpe and Jason Marquis seem like other possibilities. 
• Indians manager Eric Wedge, on the other hand, does not appear likely to be fired.
• Heyman says Stephen Strasburg is still expected to aim for $50MM after the Nationals select him first overall in June.
