The Mariners' Gregory Santos gamble was not a dramatic failure as much as an unfinished bullpen bet disrupted by injuries and poor timing.

Right-hander Gregory Santos will join San Francisco Giants' pitching staff, while Blade Tidwell was optioned to Triple-A.

The Giants swap out a talented starter-turned-temporary reliever for a perma-reliever who might be ready to contribute.

The San Francisco Giants were an out away from a perfect game and a strike away from a no-hitter before they were broken up by the Milwaukee Brewers on Sunday in a spring training game. Giants reliever Gregory Santos walked Cooper Pratt with two outs in the ninth. The next batter, Blake Burke, delivered a run-scoring double with two strikes.

The San Francisco Giants did not end up getting their spring training perfect game, or even a no-hitter, against the Milwaukee Brewers on Sunday.

Left-handed pitcher Tayler Saucedo and right-handed pitchers Gregory Santos and Trent Thornton will all hit free agency after being non-tendered by the Mariners
