"It's exciting," Hoes said. "I'm happy to be here and contribute any way I can."
Hoes said the reason for his hot start was two-fold: he credited a Fresno lineup that includes Preston Tucker, Domingo Santana, Jon Singleton and Matt Duffy, as well as an adjustment he made.
"I went to winter ball this year and tried to get back to the approach I had in 2013 when I got traded here," he said. "Last year, I tried to pull the ball more and do things that are not my game. This year, I wanted to focus on using the whole field."
Wojciechowski began the year in the rotation and has gone 0-1 with a 7.31 ERA in four games (three starts). Astros manager A.J. Hinch said long reliever Sam Deduno could start Friday, as well as Triple-A arms Jake Buchanan or Dan Straily.
"We need to get Wojo back on track," he said. "His stuff wasn't as crisp as he was in Spring Training. He hasn't gone deep into any games. ... [The roster move] was a combination of wanting to get Wojo back to what made him successful in the spring, why he made our team to begin with, and L.J. was the hottest guy down there to come up and play off the bench for us."
As for left-hander Brett Oberholtzer, who's rehabbing from a blister in Kissimmee, Fla., Hinch said he would need to be built up to 90 pitches before being called up. He threw about 35 pitches in three innings recently and could be sent out to continue his rehab at a Minor League affiliate soon.
