Fernando Martinez called up

So Fernando Martinez is on his way to Houston, and will be in uniform tonight.

Seconds after this tweet, the Astros official Twitter account tweeted that Juan Abreu (acquired in the Bourn trade), who was DFA'ed, has been claimed by the Blue Jays.

Schafer to DL, Juan Abreu DFA'd

It's a bad day for Ed Wade's Michael Bourn trade. To make room on the active roster for Brandon Barnes, Jordan Schafer has been put on the 15-day DL with shoulder separation, and to make room on the 40-man roster, Juan Abreu has been designated for assignment.

Abreu, of course, came to the Astros along with Schafer, Paul Clemens, and Brett Oberholtzer in exchange for Bourn last season. He pitched in 7 games for Houston last season, posting a 2.70 ERA over 6.2 IP. But he never made it back to the bigs this season, putting up an ugly 7.09 ERA in 45.2 IP (38 games) with Oklahoma City.

Barnes, meanwhile, is in Houston and will make his ML debut tonight.

Escalona out, Abreu up

The Astros have placed Sergio Escalona on the DL with elbow tendinitis and called up Juan Abreu from OKC.

So of the four players the Braves traded for Michael Bourn, Abreu is the second to see time with the ML team. And he's the third player from the spate of deadline trades to see the majors (Sosa, Schafer, Abreu).

Updated rosters

In light of the recent influx of prospects, here's a rundown of where they went on Eddie's Farm:

Keppinger trade

Henry Sosa - Corpus
Jason Stoffel - Corpus

Pence trade

Jarrod Cosart - Corpus
Jonathan Singleton - Lancaster
Josh Zeid - Corpus

Bourn trade

Juan Abreu - Oklahoma City
Paul Clemens - Corpus
Brett Oberholtzer - Corpus
Jordan Schafer - DL

Who are these former Braves?

Let's take a look at the players the Astros received from the Braves, shall we?

Jordan Schafer

6'1" 200lb, 24-year old lefty CF from Hammond Indiana - 3rd Round pick by the Braves in 2005.

Schafer is the best-known quantity in the deal, hitting a homer in his first career AB off of - yes - Brett Myers. In 2009, Schafer hit .204/.313/.287 for the Braves, in 50 games, and was packed back to Triple-A Gwinnett. He did come back to the Braves, hitting .240/.307/.316 in 52 games in 2011. He's currently on the DL thanks to a fractured left middle finger.

Brett Oberholtzer

6'2" 230lb LHP, 22-year old 8th Round pick in the 2008 draft by Atlanta.

Oberholtzer carries a career 25-20 record, with a 3.35 ERA / 1.16 WHIP, and a 3.79 K:BB ratio in the minors. He split time between Single-A Rome and High-A Myrtle Beach in 2010, going a combined 6-8 with a 3.78 ERA / 1.17 WHIP in 2010, and moved up to Double-A Mississippi in 2011, where he has thrown 127.2IP (still 8IP under his 2010 total), allowing 119H/53ER, 93K:42BB.

Paul Clemens

6'4" 180lb 23-year old RHP from Columbia, South Carolina, drafted in the 7th Round of the 2008 draft by Atlanta.

Clemens is also at Double-A Mississippi in 2011, where he has thrown 108.2IP, 103H/45ER, 93K:44BB for a 3.73 ERA / 1.35 WHIP. In 2010, he followed Oberholtzer's path (Rome/Myrtle Beach), and went a combined 2-4, with a 3.23 ERA / 1.37 WHIP, and a 2.25 K:BB ratio.

Juan Abreu

6'0" 180lb, 26-year old RHP from the Dominican Republic.

For Triple-A Gwinnett, Abreu has appeared solely in relief, posting a 2.25 ERA / 1.27 WHIP in 41 games. In 48IP, he has allowed 34H/12ER, 68K:27BB, and 5HR allowed. He missed all of 2007, but has the best numbers in his career coming out of Triple-A.

Astros on verge of trading Bourn

Rosenthal just announced the Braves are getting Michael Bourn for "four minor leaguers," as yet unnamed. Watch this space.

Names coming out, none of The Four Untouchables:
Jordan Schafer, CF
Brett Oberholtzer, LHP
Juan Abreu, RHP
Paul Clemens, RHP

We'll have full reaction once church is over, but right now it looks as though the edge goes to the Braves, who got what they needed without giving up any of their top four prospects.
