Gavin Williams has emerged as a fantasy baseball trade target in Week 9 due to mixed performance this season. After a strong spring training, where he recorded a 2.08 ERA over 17.1 innings, his regular season began poorly, showcasing a 5.14 ERA and a concerning number of walks. However, his recent outings show improvement with a 2.25 ERA over four starts in May, attributed to a revitalized cutter. Despite this, his high walk rate (12.4%) remains a significant concern. It's recommended to trade him while his value is inflated due to his recent success.
