Drafted in the 15th round (471st overall) by the Chicago White Sox in 2012 (signed for $100,000).
View Draft Report
Guerrero was something of a pop-up name this spring after running his fastball up to 92-93 mph early in the season, but his stock cooled down the stretch, when he has pitched more in the 85-88 range. He has a short, quick arm stroke, which helps make up for a small 6-foot-3, 165-pound frame, and durability is a significant question at this stage. His No. 2 pitch is a changeup that projects as an average pitch, and his curveball is loopy. He throws it with a high arm slot and tends to get too much on top of it and bounce it. As a lefthander who has flashed decent stuff, Guerrero could sneak into the top 10 rounds, especially because he is considered signable.

When the White Sox drafted Guerrero in 2012, they saw a lefthander with present average fastball velocity as well as a feel for a pair of secondary pitches. His career stalled early after shoulder problems limited him to just 25 innings in 2012 and 2013. He was eased into the rotation toward the end of 2014 at low Class A Kannapolis, then became a full-time rotation piece upon his return there in 2015. Guerrero spent the last two seasons at Double-A Birmingham, where he's struggled to overcome command issues. Guerrero cut his walks roughly in half from 2016 to 2017, but the White Sox would like to see further improvement. That's particularly true when it comes to repeating his arm slot. He brings his fastball between 91-93 mph and has touched 94. He backs it with a plus changeup, but needs to continue to improve his fringy curveball and slider. The White Sox also noted an improved effort on Guerrero's part to be more physically prepared every time he took the mound. Guerrero was left off the 40-man roster and was not picked in the Rule 5 draft, an indicator of how he has further work to do to be big league ready. He'll turn 24 this year and will likely move up to Triple-A Charlotte.
As a lefthander with average velocity and feel for secondary pitches, Guerrero commanded $100,000 as a 15th-round pick out of high school in 2012. Shoulder issues stymied his first two pro seasons at Rookie-level Bristol, but he began to shine with a managed workload in 2014, recording 80 strikeouts in 78 innings and finishing the year in the rotation at low Class A Kannapolis. Guerrero backed up that performance in 2015 by going 13-4, 3.08 in 24 starts and leading the White Sox system with 148 strikeouts. He works fast and throws strikes with three pitches. His 90-91 mph fastball bumps 93 and plays up because of plus life and deception. Guerrero's plus, 76-80 mph changeup is his go-to secondary weapon with excellent fading action off the barrel of righthanded batters. He changed the way he threw his changeup in 2015, using more of a two-seam fastball release and mentality, rather than pronating his wrist in the traditional fashion. It now features more drop as a result, and he's unafraid to double-up on the pitch. Guerrero throws a slurvy slider that gained more consistent power in 2015 and now grades as at least average. The White Sox say that Guerrero grew up in 2015 and began to take instruction. As a three-pitch lefty who can miss bats and throw strikes with his entire arsenal, Guerrero has No. 4 starter potential as he advances to Double-A Birmingham in 2016.
