Latest Fantasy Rumors
MLB debut might come soon
Manager Alex Cora mentioned Uwasawa as a potential rotation option after Garrett Whitlock was placed on the injured list Wednesday with an oblique injury, reports Chris Cotillo of The Springfield Republican.
ANALYSIS
The skipper said in early April that Uwasawa needed to adjust to the pitch clock and work on his splitter at Triple-A Worcester, but since then Boston's rotation injuries have mounted. The Japanese right-hander has underwhelmed in his first two starts at Triple-A with seven runs allowed across 10 innings, but he's on the shortlist as a starting option since he's already on the 40-man roster.
