Lucas Harrell is no longer and Astro.

The Astros traded the starting pitcher on Monday afternoon to the Arizona Diamondbacks for a player to be named later or cash considerations.

The trade ends Harrell's up-and-down stay in Houston.

In 2012, Harrell led the Astros with 11 wins (he went 11-11 with a 3.76 ERA). He was responsible for 11 of the Astros' 55 wins.

But Harrell struggled mightily in 2013, going 6-17 with a 5.86 ERA. Those struggles continued into this season. He started the season with an 0-3 record with a 9.49 ERA in three starts.

Harrell was designated for assignment on April 15.
