Astros Notes: Norris, Appel, Boras, Luhnow

Astros hurler Bud Norris continues to have a strong season and he figures to be one of the most sought-after trade pieces this summer, tweets Buster Olney of ESPN.com.  Norris, who was taken in the sixth round of the 2006 draft, currently has a career-best 3.39 ERA with 5.7 K/9 and 3.4 BB/9 through 12 starts.  How will this year's draft shake out for the Astros?  Here's the latest..

• Agent Scott Boras' history of being a tough negotiator has led many to theorize that the Astros will pass on Mark Appel in an effort to spread their bonus pool money and avoid drawn-out post-draft talks.  For what it's worth, Boras told Brian T. Smith of the Houston Chronicle that he has no intention of overvaluing client Mark Appel and backing the Astros into a corner if they take him. 
• Boras said he's had a couple of recent pre-draft conversations with Astros General Manager Jeff Luhnow and believes that he'll select the best available player on the board, not the player with the best monetary value.  He also believes that the Astros have yet to make up their mind on the No. 1 pick.
• Appel, Jonathan Gray, Kris Bryant, and Colin Moran are the Astros' top possibilities, with high school outfielder Clint Frazier a distant fifth, Smith writes.
