Red Sox LHP prospect Zach Penrod struck out three across four scoreless innings in a start on Saturday in the AFL.
After signing with the Red Sox in August of this year out of the independent Pioneer League and posting a 2.18 ERA for High-A Greenville, Boston sent the 26-year-old to the Arizona Fall League. The left-hander has a five-pitch repertoire, but none are considered a wipeout offering. With his excellent three innings on Saturday, he lowered his ERA to 1.29, which is the best ERA for qualified starters in the Arizona Fall League. Penrod will have to be added to the Red Sox’ 40-man roster to protect him from the Rule 5 draft, and with these results, he is likely to be added.
