Latest news
Santos elected to become a free agent Wednesday, Susan Slusser of the San Francisco Chronicle reports.
Santos cleared waivers after being booted off the Giants' 40-man roster, but he's opted to test out free agency rather than accept an outright assignment. The 26-year-old reliever has allowed five runs (two earned) over five innings in the majors this season and holds a 6.89 ERA and 11:11 K:BB over 15.2 frames at Triple-A Sacramento.

The Giants outrighted Santos to Triple-A Sacramento on Monday.
The transaction will free up on a spot on the 40-man roster for right-hander Eric Cerantola, whom the Giants claimed off waivers from the Royals. Santos owns a 6.89 ERA and 1.84 WHIP with an 11:11 K:BB across 15.2 innings at the Triple-A level this season.

Santos (adductor) was reinstated from Triple-A Sacramento's 7-day injured list Wednesday, and he allowed three earned runs on two hits and three walks while striking out one over two-thirds of an inning in Friday's 13-6 win over Las Vegas.
Santos was placed on Sacramento's 7-day injured list May 26 due to a right adductor strain. He began a rehab assignment in the rookie-level Arizona Complex League on June 19 before returning to action with Sacramento and starting Friday's contest, during which he threw 16 of his 32 pitches for strikes. Over 13 appearances (one start) at Triple-A, the right-hander owns a 6.14 ERA, 1.83 WHIP and 11:10 K:BB across 14.2 innings.

Triple-A Sacramento placed Santos on its 7-day injured list May 26 with a right adductor strain, and he returned to action in Arizona. The 26-year-old right-hander gave up two singles while throwing 16 of his 20 pitches for strikes. He has spent most of the season at Triple-A, where he owns a 4.50 ERA, 1.50 WHIP and 10:7 K:BB across 14 innings in 12 appearances.

Triple-A Sacramento placed Santos on its 7-day injured list May 26 due to a right adductor strain, MLB.com reports.
Santos maintains a spot on the Giants' 40-man roster but has spent most of the season at Sacramento, with whom he's turned in a 4.50 ERA and 1.50 WHIP over 14 innings across 12 appearances. The righty reliever is projected to return to action for Sacramento in late June or early July.

The Giants optioned Santos to Triple-A Sacramento on Sunday.
The right-hander was called up by San Francisco in late April, but he'll return to Sacramento after giving up two earned runs with a 1:3 K:BB across three appearances (5.2 innings). Santos could rejoin the Giants later in the season when bullpen depth is needed.
