Forgot to update this...
Houston went 5.1 innings tonight, giving up 3 hits (2 in his final third of an inning), 2 runs (both scored after he was pulled and Ricky Ramierez walked the bases loaded, then allowed a sac fly and double), 1 walk and 6 strike outs.
He is currently 3-0 with 30 strike outs in 32 innings, with a 1.09 WHIP, with 11 walks. He does need to drop the walk rate, but he's been looking good this season except 1 game. The last two games, the runs have been scored against the reliever.
