Ben Williamson's ascent to the major league roster of the Seattle Mariners marks him as a promising prospect, particularly for dynasty league fantasy owners. Known for his ability to avoid strikeouts, Williamson's performance during his fourth NCAA season and subsequent stint in the Cape Cod League showcased his potential as a reliable offensive asset.

Williamson's development includes notable improvements in his plate discipline and overall hitting ability. His ability to maintain a high batting average while reducing strikeouts makes him a candidate for a significant role in the Mariners' lineup. However, fantasy players should consider his projected power output and performance against left-handed pitchers, as these areas require improvement.
