| Big, strong frame; listed 6'2"-210 is accurate; major-league body; 3/4 slot; arm works well; arm strength is apparent; delivery isn't difficult, but is often rushed leading to command issues; some cause for injury concern if he consistently gets into bad habits; whips head noticeably after release. |

Fringe fastball in this outing; worked it 89-90 early in the start and bumped it up to 91-92 when he needed it; solid arm-side run; command was fringy; missed up and in the middle of the plate often but pitched out of jams; command will need to take a step forward to be effective against stiffer competition. |

Plus-plus offering; outstanding arm-speed creates lots of deception; ball dies getting to the plate; big time vertical drop; velocity is often 10-15 mph off the fastball; command was average; left it up on occasion; best when it starts at the thigh it drops to the dirt or around the ankles; very confident with the pitch. |

Fringy pitch; has good shape, but lacks big bite; can come and go; can drop it for strikes; inconsistent command/control; will flash one inning then lose it for two consecutive innings; gets on the side of it at times and turns into a slurve; playable pitch at the highest level, I think it'll get better. |

Guillon had a solid outing, giving up three runs on five hits in a nice six inning start, with three K's and three walks. He pitched out of a couple jams, going with his plus-plus changeup in big spots to limit the damage. Unfortunately, he wasn't quite right in his last handful of outings in August and was placed on the 7-day DL. Guillon had a ton of upside even up until this season, but the fastball that was up to 97 mph hasn't resurfaced and settled more in the low 90's. With that speed, the command needs to be that much better and it simply wasn't in this start. The body, changeup, and left-handedness all scream to give him more time to develop, but lots of questions loom. Can he remain healthy with Tommy John surgery already on his resume? Can he regain his fastball velocity? Will his command take a big step forward? I'm pessimistic that any of these come to fruition, but I still think he can progress enough to reach the big leagues as a reliever with that changeup and two other solid offerings. If it all clicks, the ceiling is a back-end starter that can eat some innings.
