The Astros cut ties with Lucas Harrell on Monday, six days after he had been outrighted. The perplexing right-hander was traded to the Diamondbacks for cash considerations or a player to be named later.

Harrell, 28, put together a strong 2012 in Houston, but never returned to that form. After three terrible starts this season, the Astros decided it was time to move on.

General manager Jeff Luhnow said that Harrell wanted a trade, but did not demand one.

“Lucas expressed an interest in a major league opportunity, and he should have that available to him, that he would want us to look for other opportunities out there,” Luhnow said. “I don’t know what exactly Arizona has in mind, but I do think he’s got a better chance of getting back to the big leagues with Arizona at this point than he would have had with us.”

While Luhnow said he got the sense that Harrell did want to leave, he also believed Harrell would have been content to stay with the organization.

“I think he would have been perfectly fine had we not made a trade and tried to work his way back here,” Luhnow said. “Obviously, it was a shock getting designated and then taken off the roster, waivers and all that. I think he was just going through the normal reaction process.
