Wright made eight starts and was 0-2 with a 4.29 ERA with Azucareros de Este. In 35 2/3 innings, he allowed 34 hits, 20 runs (17 earned), walked 22 and struck out 40.
"We thought he did fine," general manager Ed Wade said. "We thought it was well worth the environment for him to go down there and get stretched out and be prepared to compete for a spot in the rotation and see where it goes.
"It certainly gives us another option from a starting point and broadens Wesley's horizons with regards to the different things he can do for the club."
Wright, 24, was a starting pitcher in high school in Alabama, but he was moved to the bullpen after the Dodgers drafted him in the seventh round in 2003. Houston got him from Los Angeles in the Rule 5 Draft in 2007.
"For me, I just want to be as versatile as possible," Wright said. "Versatility is the key to being able to stick around. The fact that I have been in the bullpen in the past and knowing I could go back, that's a good thing. Whatever to help the team win is a good thing. We'll see once Spring Training gets here."
Wright went at least five innings in his first five starts in the Dominican and threw as many as 90 pitches and as many as 5 2/3 innings.
"The main thing for me was learning how to face the lineup the second time around, just being able to make the adjustments to keep the guys off balance," Wright said. "The first time guys are trying to get a feel for you, and the second time they have a feel for what you have and you make the adjustments you need to make."
Wright was named the Astros' Rookie of the Year in 2008, when he made 71 appearances in his Major League debut and went 4-3 with a 5.01 ERA. Last year, he split time between the Astros and Triple-A Round Rock, struggling to find consistency.
He was 3-4 with a 5.44 ERA in 49 games during four different stints on the Major League roster and 2-1 with a 3.32 ERA in 13 games at Round Rock. He suffered from arm fatigue near the end of the season and was on the disabled list from Aug. 12-Sept. 1 with a left shoulder strain.
Wright has been used primarily as a left-handed specialist, but lefties hit .359 against him last season (righties hit .265).
"All avenues are open for him," Wade said. "Being left-handed, he brings significant value to the club. We're pretty confident that Tim Byrdak assumes a role as one of the lefties in the bullpen. If we were to decide to go with a second one, Wesley at this point in time has a great chance to stick in that role. But again, we'll go into Spring Training with an open mind."
