Wade LeBlanc has been brought up from Oklahoma City, and Marc Krauss has been optioned back to OKC.
LeBlanc had a pretty terrible first stint with the Astros, allowing 4H/5R (4ER), 1K:3BB in 3.2IP from June 10-23. In 14 games for OKC since getting sent down, he has allowed 46H/21ER, 42K:14BB in 45IP, with a .721 OPS allowed on a .336 BABIP. And that's skewed from a July 9 outing where he gave up 11H/9ER in 3.1IP. Since that game, he's allowed 32H/11ER, 34K:9BB in 37IP.
Krauss was hitting .169/.207/.325 for Houston this season, but had played sparingly in August after the acquisition of LJ Hoes.
