<h2>Getting to know Dahian Santos….</h2>
Position: Pitcher
Throws: Right
Born: February 26, 2003
Acquired: 2019 International Free Agency
Previous ranking: 24
The Blue Jays signed Santos during the 2019 International Free Agency period, with the Venezuelan native making his professional debut in 2021. That season, he had a 5.58 ERA and a 4.50 FIP in 40.1 innings pitched between the Florida Complex League and Single-A. The following season, he had a 3.44 ERA and a 3.51 FIP in 73.1 innings pitched in Single-A with a 39.3 K% and an 11.5 BB% but struggled in his four starts at the High-A level.
Santos pitched the entirety of the 2023 season with the High-A Vancouver Canadians, where he had a 3.54 ERA and a 4.78 FIP in 48.1 innings pitched with a  27.2 K% and a 13.1 BB%. However, his final outing was on Jul. 1, 2023, before spending the rest of the season injured.
Which brings us to last season. Santos didn’t make his season debut until mid-June and finished the season with a 5.55 ERA and a 5.17 FIP between the Florida Complex League, Single-A, and Double-A. The majority of his season was pitched in the latter, where he had a 6 ERA and a 5.08 FIP in 27 innings pitched, with a 25.8 K% and a 16.7 BB%.
Santos only made three starts all season, one on a rehab assignment and two in Double-A to end his season. The most innings he pitched in a single game was three, done in one of those starts on Sep. 4 as well as one in relief. It’ll be interesting to see whether the Blue Jays see him as a starter or a bulk reliever moving forward.
In <a href="https://www.mlb.com/milb/prospects/2024/bluejays/dahian-santos-692479">MLB Pipeline’s</a><a href="https://www.mlb.com/milb/prospects/2024/bluejays/dahian-santos-692479"> mid-season update</a>, Santos ranked as their 20th-best Blue Jays prospect. Without question, his best pitch is his slider as it’s a potential “out pitch” in the big leagues according to his scouting report. Moreover, Santos’ fastball sits in the low-90s with an average changeup. The 21-year-old’s command is still a concern which gives him more of a reliever profile.
