Martinez will start the Padres' Cactus League opener Friday, AJ Cassavell of MLB.com reports.
Martinez logged 10 starts and 37 relief appearances last season with San Diego, but he's expected to have more of a permanent rotation spot steering into 2023. The 32-year-old right-hander is coming off an overall 3.47 ERA and 95:41 K:BB across 106.1 innings, and he's probably worthy of a late-round dart throw in most standard fantasy formats.
