The Washington Nationals are in a critical phase of their roster development, aiming to identify the future cornerstones among their talented young players. The front office faces the challenge of assessing which prospects will contribute significantly and which may become expendable.

Recent decisions reflect this strategy, particularly regarding pitcher Joan Adon. After going unclaimed upon being designated for assignment, Adon will remain with the Nationals, transitioning to their Triple-A affiliate. Initially signed in 2016, he reached notable heights within their prospect rankings but has struggled at the Major League level.

The Washington Nationals have signed infielder Amed Rosario to a one-year contract worth $2 million. The 29-year-old Rosario had a productive season, batting .280 with 18 doubles, three triples, three home runs, 32 RBIs, and 13 stolen bases in 103 games, playing for Tampa Bay, Cincinnati, and the Los Angeles Dodgers.

This move comes after the Nationals acquired first baseman Nathaniel Lowe from Texas and signed Josh Bell as a free agent. To make room for Rosario on the roster, Washington designated right-hander Joan Adon for assignment.

Entering his 10th year in Major League Baseball, Rosario boasts a career batting average of .273. His versatility is notable, having primarily played as a shortstop but also appearing at second base, third base, and all three outfield positions throughout his career with the New York Mets, Cleveland, Dodgers, Rays, and Reds.
