As the MLB season unfolds, it's crucial to keep an eye on lesser-known pitching prospects, especially those who may have been overshadowed by more prominent names. AJ Smith-Shawver of the Atlanta Braves is a rising star worth watching after demonstrating solid command in spring training. Despite a rocky 2023, his 4.26 ERA in the majors at just 20 years old signals potential upside, especially with recent injuries to the Braves' rotation.

Jack Leiter, a former second overall pick for the Texas Rangers, has shown improvement, especially in command, reducing his walk rate significantly this spring. With injuries in the Rangers' rotation, he could emerge as a potential fantasy asset. Will Warren from the Yankees also presents a watchful opportunity following a disastrous previous season, showcasing excellent spring stats despite recent struggles.

Lastly, Richard Fitts of the Boston Red Sox, acquired in a trade with the Yankees, has demonstrated effective command and could become a reliable back-of-the-rotation arm. Keep an eye on these prospects, as they may provide value in fantasy leagues as the season progresses.
