The Giants signed righty Doug Mathis yesterday, according to the Pacific Coast League's transactions page. He's already made a start for the Fresno Grizzlies. The 27-year-old had been released by the Indians last week.
Mathis posted a 5.66 ERA, 5.5 K/9, 3.1 BB/9, and 0.7 HR/9 in 89 Triple-A innings last year, mostly as a starter. He was worse with the Rangers in 22 1/3 relief innings, allowing seven home runs and 30 hits.
