The Red Sox have designated righty Zeke Spruill for assignment, Tim Britton of the Providence Journal reports on Twitter. His 40-man spot was needed for the promotion of Noe Ramirez.
The 25-year-old has worked exclusively at Triple-A this year for Boston, which acquired him from the Diamondbacks on the same day the Wade Miley deal went down. He owns a 5.40 ERA with 3.9 K/9 against 2.7 BB/9 over 53 1/3 innings for Pawtucket.
Spruill had spent time with the D’Backs in each of the last two seasons. In total, he’s thrown 34 big league frames, posting a 4.24 ERA and striking out 23 batters while issuing nine walks.
