Most of the international signees who make headlines are 16 years old and sign for large bonuses. When the Twins signed Colina, he was already 18 and received just $8,000. After a summer in the Dominican Summer League and one in the Appalachian League, the right-hander advanced to full-season ball for the first time in 2018, but really jumped onto the radar a year later by starting in the Florida State League and finishing it in Triple-A.
While he is undersized at 5-foot-11, Colina is stocky and strong and comes at hitters with a power repertoire. He’ll touch 98 mph with his fastball regularly and has hit triple digits in the past with good life to it. His slider is his go-to, a power breaking ball that misses a ton of bats. He does have a changeup, but it’s below average and he doesn’t throw it much.
The development of that pitch, along with continued refinement of his command, will be the keys to whether Colina can remain in a starting role. Some of it might depend on big league need, but he could end up being an impact reliever that comes in late in games with a nasty fastball-slider combination.
Scouting grades: Fastball: 65 | Slider: 55 | Changeup: 40 | Control: 45 | Overall: 45
Not every successful international signee was a big-bonus sign on top prospect lists. Colina signed for just $8,000 back in September 2015 and didn't make his full-season debut until 2018. He continued to fly under the radar until 2019, when he pitched his way from the Class A Advanced Florida State League up to Triple-A at the end of the year despite missing the first month of the season with a back strain.
At 5-foot-11, 240-pounds, Colina is the quintessential undersized, stocky and strong power right-hander. He's hit triple digits in the past and touches 98 mph on a consistent basis. He has a slider that flashes plus and generated the fifth-best swing-and-miss rate among all sliders in High-A/Double-A in 2019. He has a changeup, but it's far behind the other two offerings and needs work if he wants to remain a starter.
With an up-tempo delivery, Colina has struggled with command for much of his career, though he took a big step forward in terms of strike-throwing in 2019. Even so, he could be destined for a bullpen role, where that fastball-slider combination could be very effective late in games.
