The Astros have traded reliever Wilton Lopez and a player to be named to the Colorado Rockies for Alex White and minor league pitcher Alex Gillingham.
White, a pitcher, was the 15th overall pick by the Cleveland Indians in 2009. Last season, the 24-year-old went 2-9 with a 5.51 ERA in 23 apperances with the Rockies.
Gillingham, 22, was an 11th-round pick in 2011. He spent last season at Single-A Asheville, where he went 6-8 with a 3.66 ERA.
"Wilton Lopez has been a big part of our organization for the last few years and it's definitely a loss for us in that perspective," Astros GM Jeff Luhnow said to CSN Houston's Marius Payton. "He was our closer at the end of the year. He's been a very effective reliever."
White has been added to the Astros' 40-man roster, which stands at 37 after the move.
"But when we look at where we are as an organization and what we have to accomplish," Luhnow said, "to be able to bring in a starting pitcher like Alex White, who is at the beginning of his major league career with a lot of upside, guy I spent some time scouting as an amatuer. And we followed him. He pitched against us this year in COlorado. ... We felt like this was an opportunity we had to take advantage of."
The Astros were reportedly close to trading Lopez to the Phillies last week but that deal fell through after Lopez took a physical for the Phillies. It was unclear, however, if health concerns were the reason for the deal falling through.
The 29-year-old Lopez had been with the Astros for four seasons. Last year, he had a 6-3 record with a 2.17 ERA in 64 games with Houston. He had 10 saves.
Over the last three seasons, Lopez has a 13-11 record with a 2.64 ERA with 160 strikeouts and 31 walks.
