Lyles' promotion is his second of the season. In his two stints with the RedHawks, Lyles is 5-0 with a 3.49 ERA.
To make room for Lyles, relief pitcher David Carpenter was optioned to the RedHawks.
Carpenter had spent the entire season with the Astros, going 0-2 with a 4.02 ERA.
Lyles replaces Kyle Weiland in the Astros rotation. Weiland was placed on the disabled list in late April with bursitis in his right shoulder.
BROADCASTER WRITES BOOK ON TEAM NAMES
Tucson broadcaster Tim Hagerty recently released a book on minor league team names and their origins.
The book “Root For The Home Team, Minor League Baseball's Most Off-the-Wall Team Names,” covers teams in 49 states (all but Alaska) and Canada.
Hagerty came up with the idea in 2004, when he broadcast games for the Idaho Falls Chukars.
“People were constantly coming up to me and asking me where the name came from,” Hagerty said.
Entries include the Lawton Medicine Men, Ilion (N.Y.) Typewriters and Kalamazoo (Mich.) Celery Pickers. Each entry includes the origin of the name as well as on-the-field fact about each team.
The book is available at bookstores and online at Amazon.com and BarnesandNoble.com.
