The Athletics promoted right-hander Trevor Cahill from High-A Stockton to Double-A Midland of the Texas League. Cahill, Oakland's second-best prospect according to Baseball America, had a 2.07 PERA and a 10.6 K/9 in 87.3 innings in the California League.


The Blue Jays signed first baseman David Cooper, Toronto's top pick in the 2008 First-Year Player Draft, to a contract and assigned him to Auburn of the New York-Penn League. Cooper, the 17th overall pick, got a $1.5 million bonus.


The Indians signed third baseman Lonnie Chisenhall, their top pick in the 2008 First-Year Player Draft, to a contract and assigned him to short-season Class A Mahoning Valley. Chisenhall, the 29th overall pick, got a signing bonus of $1.2 million.


Indians center field prospect Brad Snyder did not play last night after hitting his head on a concrete overhang in the Triple-A Buffalo Bison’s clubhouse tunnel. The Tribe’s 25th-best prospect according to Baseball America is having a disappointing year (.246 EqA in 195 AB). In the 2008 Rule 5 Draft, the Tribe protected Snyder rather than left fielder Brian Barton, who is now a fourth outfielder for the St. Louis Cardinals.
