Stammen was sent down to Double-A Akron on Thursday.

EDGE Analysis

Stammen pitched in three games with Triple-A Columbus over the past two weeks, allowing two earned runs and four hits while striking out eight batters over three innings of work. The 32-year-old missed most of the 2015 season with a torn right flexor tendon and could potentially make it back to the big league time by the time the second half of the season starts July 15.
