The Mariners could be adding a power arm to their bullpen in the weeks after the All-Star break, and it won’t come via trade. Hard-throwing right-hander Shae Simmons made a strong initial appearance in his rehab assignment with the Arizona League Mariners on Thursday night.
Simmons tossed one inning (14 pitches), allowing one hit and striking out two batters.
“He threw great,” said general manager Jerry Dipoto. “He was 95-97 mph and his average velocity was 96 mph. He felt good coming off the mound with good break on his breaking ball. Most importantly, he came out feeling good.
