Red Sox promoted LHP Eduardo Rivera to Triple-A Worcester.

The 22-year-old looked great in two starts at Double-A this season, allowing one run on six hits in 10 innings with a 16/3 K/BB ratio. However, this says more about the Red Sox’s lack of starting pitching depth. With Sonny Gray (hamstring) on the injured list, and all of Kutter Crawford, Johan Oviedo, Tanner Houck, and Patrick Sandoval on the injured list, the Red Sox don’t have many starting pitching options at Triple-A. Payton Tolle is likely being called up to the big leagues to take Gray’s spot in the rotation, which leaves Jake Bennett and Tyler Uberstine as the only true starting-pitcher options at Worcester. The Red Sox will hope not to have to turn to Rivera as an option this season, but he’s now one step closer.
