Astros sent LHP Mark McLemore outright to Triple-A Round Rock.
Trying to turn McLemore into a starter this spring was misguided at best, but it did end up increasing Houston’s chances of keeping him. He always belonged in a relief role, but since he struggled in longer stints, the Astros had no problem getting him through waivers. The 27-year-old had a 12.91 ERA and a ridiculous 1/13 K/BB ratio in 7 2/3 innings this spring. He made 29 relief appearances for Housto last year and had a 3.86 ERA and a 35/18 K/BB ratio in 35 innings.
