Multiple sources confirmed to Pinstriped Prospects on Wednesday evening that right-handed pitcher Jonathan Loaisiga has been promoted to Double-A Trenton. He is expected to start for the Thunder when they welcome in the Harrisburg Senators to ARM & HAMMER Park on Thursday night.
In four starts for the Tampa Tarpons, Loaisiga has gone 3-0 with a 1.35 ERA while striking out 26 and walking just one in 20 innings of work in the Florida State League. Loaisiga was the FSL Pitcher of the Week in early April.
The journey for the 23-year old Loaisiga to reach this point is not one that came without obstacles. The Nicaraguan-native was originally signed as a free-agent by the San Francisco Giants in 2012. He played just one season in 2013 due to injuries before the Giants opted to release him in 2015.
The Yankees inked Loaisiga to a minor league deal in 2016 shortly after he had agreed to play in the Italian league. Shortly thereafter, the righty was forced to undergo Tommy John surgery which cut his campaign short.
In 2017, Loaisiga worked his way back and managed to pitch 32 2/3 innings between the Gulf Coast League and the New York Penn League. His mid-90’s velocity had returned and he featured good command of his curveball and changeup. In 11 starts, Loaisiga fanned 33 batters and walked just three while holding the opposition to a .148 average against. Read our full scouting report and breakdown of the right-handed here.
Loaisiga was added to the 40-man roster over the winter in order to protect him from selection in the Rule 5 Draft.
