Washington Nationals right-handed pitching prospect Jarlin Susana is a name to monitor in spring training. The right-hander is currently considered the No. 87 overall prospect on MLB.com and the No. 4-ranked prospect in the Washington system. He began the 2025 campaign with High-A but needed only nine innings to prove he was ready to join Double-A Harrisburg. With the Senators, Susana flashed immense strikeout upside, tallying 79 across 47 1/3 innings of work. In this stint, the 21-year-old posted a solid 3.61 ERA with a 1.39 WHIP. However, Susana underwent right lat surgery late in the second half, which could potentially limit him in spring training. While Susana was not in the mix to debut in Washington in the first half of 2026, if he continues this high-end production, he could make a strong case to debut later in the year.

Pittsburgh Pirates left-handed prospect pitcher Hunter Barco is expected to compete for a role in the starting rotation during spring training. Last season, the southpaw was promoted in September for his MLB debut. Across three innings of work (all out of the bullpen), the lefty did not allow a run and struck out three hitters. He began 2025 with Double-A but needed only 25 2/3 innings to prove he was ready to join Triple-A. During this brief stint at Double-A, the left-hander did not allow a run and held a dominant 0.70 WHIP. At Triple-A Indianapolis, Barco logged 73 2/3 innings with a 3.79 ERA and a 1.37 WHIP. He tallied 82 strikeouts and 42 walks. Managers in deeper leagues should keep an eye on his progress in camp, as he will likely be competing for a starting role alongside Thomas Harrington. If he can crack the rotation, he would have sleeper appeal in deeper 12+ team formats, given his strikeout potential.

Milwaukee Brewers right-handed pitching prospect Logan Henderson looked quite comfortable in his first taste of the majors last season and appears primed to take on a large role in 2026. Through his first 25 1/3 innings with the Brewers (five starts), the former fourth-round pick posted an elite 1.78 ERA with a 0.99 WHIP. Henderson struck out 33 batters and allowed free passes at an 8.1% rate. He generated a strong 32.8% hard-hit rate and a 32.6% chase rate, suggesting his strikeout totals should remain high over a full season. However, the right-hander saw his workload closely monitored and dealt with injuries and was eventually shut down with a flexor strain in the second half. Fortunately, he is not expected to face any limitations in spring training. With Freddy Peralta's name in many trade discussions, Henderson appears poised not only for a spot in the rotation but also to take on a significant role in the pitching staff in the upcoming season.

According to Derrick Goold of The St. Louis Post-Dispatch, the Cardinals plan to give top infield prospect J.J. Wetherholt a chance to make the Opening Day roster. Goold noted that the team will give him "every opportunity" to be in the team's Opening Day lineup. Wetherholt, who is viewed as St. Louis' top prospect and the No. 5 overall prospect in the sport on MLB.com, was in strong contention to debut in the second half of 2025. The former seventh overall pick from the 2024 MLB Draft opened the season with Double-A but needed just 62 games to reach Triple-A Memphis. Through his first 47 games with Triple-A, Wetherholt held a stellar .314/.416/.562 line with 14 doubles, 10 home runs, and nine stolen bases. With third baseman Nolan Areando now in Arizona, Wetherholt faces even less competition to earn a key role. Managers should closely monitor his status in camp as he would become a must-draft player in all formats once named to the final roster.
