Miami Marlins vs San Francisco Giants Prediction, Odds and Picks for Today, 04/25/26

The Miami Marlins and San Francisco Giants will continue a 3-game series when they meet again in San Francisco on Saturday. Miami took the opener 9-4, but a much lower-scoring affair can be expected today. My Marlins vs Giants pick is Under 7.5. Quite simply, the Giants’ offense stinks. They are dead last in all of Major League Baseball in runs scored (85) with room to spare (no other club has fewer than 91). San Francisco had gone 4 straight games without crossing the plate more than 3 times before they did so 4 times on Friday. The home side will have a tough time generating much of anything on Saturday against Miami starter Eury Perez, who fired 6.0 innings of shutout baseball with 7 strikeouts and just 1 run during his most recent appearance against Milwaukee. The Giants have little familiarity in this matchup, which should give Perez an advantage. The Giants’ current lineup is a combined 3-for-8 all time against Perez with 1 extra-base hit (a double by Matt Chapman).

Fortunately for San Francisco, it should also be able to subdue Miami’s bats. Robbie Ray (2.86 ERA, 1.09 WHIP) is taking the mound and has not delivered a single poor start in 2026. His worst stat line is 6.0 innings with 3 runs allowed. The southpaw’s most recent home start saw him work 6.0 innings without giving up a single run to the Phillies. Ray has absolutely owned this Marlins lineup, which is a combined 2-for-17 lifetime against him with zero extra-base hits and 9 strikeouts. All things considered, give me the under.
