10:36pm: Jonathan Mayo of MLB.com provides us with a look at the newest Cubs, Ronny Morla and Matt Spencer.
Mayo characterizes Morla as a "solid mid-range" prospect and notes that he has been able to maintain a 93-94 MPH fastball as a starter. He also speculates that he could increase his velocity into the mid-90s if he is moved to the bullpen.
Spencer, meanwhile, is a solid athlete, especially when considering he is 6'4, 225 lbs. He has the versatility to play first base but his strong arm makes him more intriguing as an outfielder. In fact, there was once talk of him being drafted as a pitcher during his time at Arizona State.
5:51pm: Oakland will receive $1MM from the Cubs to help offset Aaron Miles' $2.7MM contract, according to Gordon Wittenmyer of the Chicago Sun Times (via Twitter).
5:35pm: The other two players in the deal are Ronny Morla and Matt Spencer, tweets Brent S. Gambill of Sirius XM. The Cubs will also give the Athletics cash considerations as part of the deal.
5:18pm: The Cubs have traded Jake Fox and Aaron Miles to the A's for Jeff Gray and two minor-leaguers, according to ESPNChicago.com.
Fox is the more attractive of the two for Oakland, as he has performed quite well in the Cubs' minor league system over the last three years. The 27-year-old took it to another level in '09 when he posted a remarkable slash line of .409/.495/.841 in 45 games for Chicago's Triple-A affiliate. This led to a promotion in late May in which he recorded a .779 OPS with 11 HRs in 241 plate appearances.
Miles disappointed the Cubs with his 2009 performance after receiving a two-year deal worth $4.9MM. The second baseman recorded an atrocious .466 OPS in 74 games.
One wonders if the addition of Fox could mean that Jack Cust's time in Oakland is through, as he may not be tendered an offer.
