The Giants have designated lefty Williams Jerez, per a club announcement. That opens a roster space for the return of veteran hurler Johnny Cueto, who’ll start tonight after working back from Tommy John surgery.
The San Francisco organization carried Jerez on the 40-man all year long after picking him up in a late-spring trade. The 27-year-old permitted only a pair of earned runs in his six MLB innings, but allowed six free passes while striking out four.
Otherwise, Jerez turned in solid numbers at Triple-A this year, working to a 3.86 ERA with 9.8 K/9 against 2.6 BB/9 over 56 frames. He was especially effective against opposing lefties, holding them to a .574 OPS.
