Hard-throwing reliever Shae Simmons could be ready to provide a boost to the Mariners’ bullpen shortly after the All-Star break.
Simmons, 26, began a rehab assignment Thursday by pitching one scoreless inning for Peoria in the Arizona Rookie League. He faced three batters and struck out two.
"He threw great," general manager Jerry Dipoto said. "Average velocity was 96 (mph). He felt good coming off the mound. Had good break on his breaking ball in a 14-pitch inning.
"He has a throwing progression that takes him through July 17. On July 17, if everything holds as planned, he should be ready (for the Mariners) to make a decision on whether we add him here or continue on at the minor-league level.
