Drafted in the 3rd round (83rd overall) by the Miami Marlins in 2008 (signed for $478,000).
View Draft Report
Tall and stringy with a basketball player's build at 6-foot-5, Olmos delivers his 87-89 mph fastball toward home plate with a sidearm, buggy-whip motion. His projectable frame and loose arm action suggest Olmos will significantly increase his velocity as he fills out, and he has already touched the low 90s several times. An Arizona recruit, Olmos exhibits a fine feel for his secondary pitches. His slow curve shows sweeping movement with a hint of wiffle-ball action. He also offers a changeup that has a bit of screwball rotation. Mechanically, Olmos does an excellent job of keeping his front side closed and showing the piping on his right pant leg to the hitter as long as possible. However, in his delivery he wraps his arm and needs to get fuller extension on his finish. Also, his arm slot varies from fastball to curve, and he tips his breaking ball by "screwing in a light bulb" as he grips the ball in his glove. All of these problems should be easily correctable.

Shoulder problems limited Olmos to four starts his first two seasons. The Marlins shifted him to the bullpen midway through the 2012. He made his big league debut last June, then struggled to repeat his delivery after returning to Double-A Jacksonville. Olmos' boring fastball picked up velocity in his new role and now runs in the mid-90s. His breaking ball is a hard, biting slider that can be an average pitch. His average changeup features a little fade and is a true third offering. Olmos struggles to maintain his timing because of his long stride and long arms. He also tends to finish too upright. Olmos could become a situational lefthander, though he was better against righties last year. A good spring could land him in Miami.
Shoulder problems limited Olmos to four starts in his first two seasons after he signed for $478,000 as a thirdround pick in 2008. Finally healthy last year, he made his full-season debut and got in 25 starts at Greensboro, though he averaged less than five innings per outing. A lean, projectable lefty with a loose arm, Olmos throws a lively 89-92 mph fastball. He has thrown two breaking balls in the past, but last year he scrapped his curveball and went with his slider, which can become average if he tightens it up. His changeup is another potential average offering. He relied on it too heavily early in 2010, which cost him some overall arm speed. Olmos' pitches can flatten out when his arm slot wanders, and that usually happens when he slows his tempo down. When he pitches more quickly, he's more likely to keep his arm and get a good downhill plane on his pitches. He must repeat his delivery more consistently, keeping his arm and body working together. Profiling as a No. 4 or 5 starter, Olmos will advance to high Class A this year and work on commanding his fastball so he can pitch deeper into starts.
If Olmos could just stay healthy, the Marlins believe he could really take off. After spurning Arizona to sign for $478,000 as a third-round pick out of high school, he was shut down with shoulder tendinitis after one start in his 2008 pro debut. His second was interrupted by shoulder surgery that was initially expected to be serious but turned out to be minor. Some fraying of his labrum was repaired, and Olmos was back pitching at the end of the season in the Rookie-level Gulf Coast League. His fastball sits at 89 mph and touches 92, and the Marlins believe he could add velocity because he has a live, loose arm and lean, projectable frame. He throws from a high three-quarters arm slot, and his changeup has shown screwball rotation when it's working. He features both a slow curveball at 70-72 mph and a slider at 73-76 mph. His work ethic is unquestioned, as his body got stronger during his rehab period. Olmos is highly motivated to get rolling now that his health issues have been cleared up. Florida may take things slow with him, so he could begin 2010 in extended spring training and head to short-season Jamestown in June.
The Marlins took high school lefthanders with their second- and third-round picks in the 2008 draft, with Olmos following Brad Hand. Olmos, who had committed to Arizona, signed for $478,000 in the third round. He carries tremendous projection with his live, loose arm and a tall, skinny frame. When he first showed up at Florida's training base in Jupiter, his arm slot was all over the place, depending on what type of pitch he was throwing. With the help of roving pitching coordinator Wayne Rosenthal, he settled on a high three-quarters delivery. Olmos had a bout of shoulder tendinitis that caused him to be shut down after one start in the Gulf Coast League, but his fastball was back up to 91 mph with tremendous life after he returned for a fall minicamp. His changeup needs significant improvement for him to take it from the bullpen to the game, but it has screwball action when it's on. His slow 70-72 mph curveball and his 73-76 mph slider are solid breaking pitches for which he has a good feel. His mechanics are sound and he does a nice job of keeping his front side closed. Olmos has a pleasant personality and a willingness to work. Because he has limited pro experience, he'll probably open 2009 in extended spring training before heading to Jamestown in June.
