After starting the 2024 season off well, today’s prospect suffered season-ending surgery.

This is Blue Jays Nation’s annual Pre-Season Prospect Countdown, this time looking at the top 40 prospects in the organization. We’ll look at the player’s stats, my observations, and other publications&#8217; scouting reports if available.
Let’s take a look at our 16th-best Toronto Blue Jays prospect, Landen Maroudis!

<h2>Getting to know Landen Maroudis…</h2>
Position: Starting pitcher
Throws: Right
Born: December 16, 2004
Acquired: 4th-round, 2023 draft
Previous ranking: 15th
Pitching for Calvary Christian High School in Clearwater, Florida, Maroudis was selected in the fourth round of the 2023 draft by the Blue Jays. He signed for a reported bonus of $1.5 million, well above the $547,100 slot value for this pick. Like many pitchers the Blue Jays select out of high school, Maroudis didn’t make his professional debut until the following season.
Although it was brief, it was a heck of a start to his professional career by the right-handed pitcher. Starting the season with the Single-A Dunedin Blue Jays, Maroudis threw four perfect innings in his professional debut, striking out five batters in the process. His second start saw him give up his first career earned run while walking and striking out four batters. Maroudis pitched 2.1 innings in his final start with three strikeouts but left that game early.
It turned out that the then-19-year-old needed surgery for his elbow like many Blue Jays’ minor league pitching prospects did in 2024. In late May, Maroudis underwent an operation that put a brace in his pitching elbow. Pitchers usually return quicker with this surgery rather than full Tommy John surgery, so he’ll likely be back at some point in 2025.
Despite the injury, Maroudis ranked as <a href="https://www.mlb.com/milb/prospects/2024/bluejays/landen-maroudis-805793">MLB Pipeline’s </a>14th-best Blue Jays prospect in their mid-season update. Standing at 6’3”, 190 lbs, Maroudis reached 93-95 mph with his fastball, showed an advanced changeup, and has two excellent breaking balls, a slider and a curveball. He&#8217;s still young and hopefully, the missed season doesn’t impact his development too much.
