For the Astros, it's Jordan Lyles (2-5, 5.40) taking the mound. Lyles, who was once Houstons top pitching prospect, has not found much success to begin his career. The former #42 Baseball-America prospect made 20 appearances with 15 starts last season in his rookie year. He worked his way to a 5.36 ERA and a 4.53 FIP. He never put up big strikeout numbers in the upper levels of the minors, and his 6.4 K/9 in 2011 seemed about right. He also had slightly under 2.5 BB/9.
This year, Lyles stands at a 5.40 ERA and a 5.08 FIP. His K/9 has dipped to 5.89 while his BB/9 has risen to 3.27. He suffered through perhaps his worst outing of the season his last start, against the Pirates. He was only able to pitch four innings after giving up seven runs on nine hits. Prior to that he was on a nice streak. In his previous three games, he had a 3.06 ERA with a .623 opponent OPS. Still, the Astros have to be worrying that their former prize prospect might not develop the way they hoped he would.
Lyles throws three pitches predominately: A 91 MPH four seamer (54%), a 79 MPH curveball (20%) and an 86 MPH slider (16%). He has yet to face a Brewers batter at least ten time.
