Blake Beavan has "signed" with Navarro College, according to the DMN blog...I assume they mean, signed a letter of intent, or whatever it is you do to commit to a juco in college baseball.
This is likely a negotiating tactic, although if the Rangers and Beavan can't work out their differences, it means Beavan will be draft-eligible in 2008 after pitching for a season for Navarro.
I can't see Beavan improving his stock enough in a season at Navarro to significantly improve his signing bonus.
