The Dodgers signed Sequera out of Venezuela for just $10,000 in 2014, a bonus that now looks like a steal given the raw stuff he has shown on backfields this spring. He spent most of 2017 in the Rookie Pioneer League after appearing in a handful of games for Class A Great Lakes early in the season. With frequent bouts of wildness and the typical probability questions that accompany most 20-year-old flamethrowers, Sequera falls into the “extreme risk” category. That said, his physicality and power stuff should put him on the radar of deep-dive prospect watchers.
Just 6’1’’ and 165 pounds when he signed, Sequera has filled out into a powerful frame that coaches estimate now stands closer to 6’3’’ and 195 pounds. He’s broad through the shoulders and waist, with an extremely fast arm that generates plus fastball velocity and hard curveball spin. There is noise in the finish of an upbeat semi-windup, and his issues repeating his delivery and finishing off-line are why the strike zone eludes him at times. His heavy fastball sits at 94-to-95 mph, scraping 97 mph frequently in my viewing. A hard, sharp-biting curveball at 78-to-80 mph got lots of swings and misses from right-handed bats. His changeup might be a tick overthrown at 86-to-88 mph, but he flashes encouraging late arm-side dive on his best ones.
