Now that Wandy is gone, Dallas Keuchel is the only starting left-hander for Houston.
The 24-year-old has looked brilliant at times, but has also had his share of struggles.
In just his second start in the majors, the Tulsa, Oklahoma native tossed a complete game, allowing just one run and keeping his pitch count at 108 over nine innings of work.
However, since then, he has been sent down and brought back up, seeing his share of success and hardship on the hill.
Recently, he experienced the polar opposite of his complete game, allowing seven runs in 3.1 innings, throwing 79 pitches.
The big difference between his poor performances and his successful outings has been his command.
In his complete-game victory over the Indians, he walked only one batter and hardly wasted a single pitch, but in his four other starts, he has walked 18 and struggled to keep his pitch count down.
Keuchel must continue to work on his command, because when he's on, he has all of the qualities of a top-of-the-rotation starter.
