Rockies vs Giants Prediction: San Francisco Aims to Close Series Strong at Oracle Park

Struggling Rockies Head Into Final Game of Oracle Park Series

The Colorado Rockies continue their disastrous start to the 2025 season as they prepare for the series finale against the San Francisco Giants on Sunday, May 4th. With an abysmal 6-27 record, Colorado has dropped two of the first three games in this four-game set at Oracle Park, where they’ve historically struggled to compete.

Saturday’s contest perfectly exemplified the Rockies’ season-long frustrations. Despite building a promising 3-1 lead through the top of the sixth inning, Colorado’s pitching collapsed in the bottom half of the frame, surrendering five runs en route to a deflating 6-3 defeat. The bullpen implosion spoiled a decent start from Blalock, who had limited the Giants to just two hits and one run through five innings.

This latest setback extends a troubling pattern for the Rockies, who have now lost 10 of their last 12 games and find themselves firmly entrenched at the bottom of the NL West standings. Their road performance has been particularly concerning, with a 2-16 record away from Coors Field highlighting their struggles to compete outside of Denver’s friendly confines.

San Francisco Giants Riding Momentum at Home

The Giants (21-13) enter Sunday’s matchup with considerable momentum, having captured two of the first three games in this series. Saturday’s come-from-behind victory showcased San Francisco’s resilience and offensive firepower, with Matt Chapman delivering the decisive blow via a grand slam during their five-run sixth inning explosion.

Behind strong starting pitching and timely hitting, the Giants have established themselves as legitimate contenders in the competitive NL West. Their 11-5 home record at Oracle Park demonstrates their comfort in the bay area, particularly against division opponents like Colorado.

San Francisco’s pitching staff has been exceptional this season, compiling a 3.45 ERA with a 1.22 WHIP and limiting opponents to a .231 batting average. Offensively, the Giants have generated consistent production with 155 runs scored, led by Wilmer Flores (7 HR, 29 RBI) and Matt Chapman (7 HR, 21 RBI).

Pitching Matchup: Webb vs. Marquez Creates Massive Advantage for Giants

Sunday’s pitching matchup heavily favors the home team, with San Francisco sending ace Logan Webb (3-2, 2.83 ERA, 1.21 WHIP) to the mound against Colorado’s struggling German Marquez (0-5, 9.82 ERA, 2.06 WHIP).

Webb has been exceptional at Oracle Park this season, particularly against division opponents with losing records. His ability to generate ground balls and limit hard contact makes him ideally suited for the spacious confines of his home ballpark. The right-hander has recorded six or more strikeouts in six of his last seven home starts as a favorite, demonstrating his dominance in these favorable situations.

Marquez, meanwhile, continues to search for answers during a nightmare start to his 2025 campaign. The veteran right-hander has surrendered at least five earned runs in four consecutive starts, pushing his ERA near double digits at 9.82. While he’s historically performed well in Sunday day games (recording 4+ strikeouts in 24 of his last 25 such appearances), the overall body of work suggests another difficult outing against a Giants lineup that’s connecting well at home.

Insights About This Matchup

Why has German Marquez struggled so much this season?

Marquez’s 9.82 ERA stems from mechanical issues affecting his control (26 hits and 9 walks in just 25.2 innings) and diminished velocity following his return from Tommy John surgery. His fastball velocity has dropped nearly 2 mph from his pre-injury levels, making his secondary pitches less effective and leaving him vulnerable against disciplined lineups like San Francisco’s.

Can the Rockies turn their season around anytime soon?

Colorado’s fundamental issues run deep, with the worst pitching staff in baseball (5.24 ERA) and an anemic offense batting just .207 as a team. Their road performance (2-16) suggests structural problems that won’t be quickly resolved. The organization appears headed for a midseason sell-off of veterans like Bryant and McMahon as they pivot toward rebuilding around younger talents like Jordan Beck and Hunter Goodman.

How important is this series for the Giants’ division aspirations?

Extremely important. With the Dodgers and Padres both fielding competitive rosters, the Giants must capitalize on matchups against struggling division opponents like Colorado. These “must-win” series against bottom-dwelling teams could ultimately determine playoff positioning in the competitive NL West. San Francisco’s 21-13 start places them firmly in contention, but maintaining dominance against weaker opponents remains crucial for their postseason hopes.
