Díaz heads to San Francisco as extra organizational relief depth at Triple-A Sacramento after making one relief appearance last year for the Astros. The 30-year-old journeyman righty has logged 88 appearances (eight starts) between three different clubs at the big-league level dating back to 2017. He’ll presumably get a chance to compete in spring training for a spot in the Giants’ season-opening bullpen.

Diaz was released by the Astros on May 29 after posting an unsightly 9.64 ERA for Triple-A Sugar Land. The Tigers will give the 29-year-old a look regardless. If Diaz was to pitch well enough for a promotion, Detroit would have to add him to the 40-man roster.

The Astros removed the 29-year-old hurler from their 40-man roster earlier in the week, and after he went unclaimed on waivers he chose to explore the free agent market. After scouring the market for a day though, he decided his best landing spot would be returning to the Astros. He’ll continue to function as extra bullpen depth at Triple-A Sugar Land.

Díaz will search for a new opportunity elsewhere after going unclaimed on waivers after being removed from Houston’s 40-man roster. The 29-year-old righty made just one relief appearance for Houston prior to being designated for assignment.
