Track Record: Loaisiga is one of the better gems unearthed by the Yankees’ pro scouting staff. The Giants released Loaisiga after shoulder injuries sidelined him for two seasons. The Yankees liked what they saw in a tryout camp, but soon after they signed him he needed Tommy John surgery. The Yankees were rewarded with a pitcher with electric stuff. He made his big league debut in 2018 but also missed a month with a sore shoulder.
Scouting Report: Loaisiga missed enough time with injuries throughout his career that he needed to be added to the 40-man roster after the 2017 season even though he had barely pitched in full-season ball. But he jumped from Class A to the major leagues in just two months thanks to three pitches that grade as above-average or better. He throws a plus fastball that sits 95-96 mph and touches 98, though it is straight enough that it doesn’t miss a lot of bats. His fastball sets up a hard changeup that grades as plus. His mid-80s curveball is more of an above-average offering, but on his best days, it is a plus pitch that gets swings and misses. Nothing in Loaisiga’s delivery precludes him from throwing strikes.
The Future: Loaisiga could be a mid-rotation starter if he can stay healthy, but that’s a big concern.
Loaisiga originally signed with the Giants in 2012, but he was released after missing the 2014 and 2015 seasons with recurring injuries. The Yankees signed him out of a tryout camp in 2016. He pitched just 2.1 innings with low Class A Charleston before landing on the disabled list again with Tommy John surgery. This year, however, the Yankees finally saw the pitcher they signed when he blew away the competition at short-season Staten Island. He consistently sat in the mid-90s and touched as high as 98 mph with his fastball. He paired the pitch with an 11-to-5 curveball in the low-80s that showed plenty of depth and helped Loaisiga whiff 33 in 33.2 innings this year. He also throws an 87-88 mph changeup with sink, though he could stand to drive the pitch down in the zone better. If Loaisiga can stay healthy, his fastball and curveball combination give him a chance to pitch in the back of a big league bullpen. If he can show improvement with his changeup, however, he has an outside chance at a long-term spot in a rotation.
Scouting Reports
After signing the former Giants farmhand out of a tryout camp and waiting while he came back from Tommy John surgery, Loaisiga has rocketed through the system. He was placed on the 40-man roster in the offseason, which made his callup in June more convenient. His three-pitch mix allowed him to flash mid-rotation potential over his first few big league starts, but he’s landed on the disabled list with shoulder soreness.
