Cards Are Still Alive For A Playoff Berth
The Cardinals showed resilience in Monday’s 6–5 win, rallying from a two-run deficit with a four-run fifth inning that flipped the momentum. Iván Herrera’s two-run homer was the turning point, and Alec Burleson continued his strong September with another RBI single. José Fermín added a key run-scoring hit, and the bullpen held off a late Giants surge to seal the victory. It was a gritty performance from a team that’s been out of playoff contention for weeks but continues to play with pride and purpose down the stretch.
St. Louis has now won three of its last four and sits at 77–80, with a chance to finish the season above .500 if they can close strong. Offensively, the Cardinals have leaned on Burleson, Brendan Donovan, and Lars Nootbaar to generate consistent contact and situational hitting. Jordan Walker’s development has been a bright spot, and Nolan Arenado remains a steady presence despite a dip in power numbers. The lineup has done a better job of working counts and avoiding double plays, which plagued them earlier in the season.
On the mound Tuesday is Andre Pallante, who’s had an uneven season but still offers upside when his sinker is working. With a 5.17 ERA and 18 home runs allowed, Pallante will need to keep the ball down and avoid falling behind in counts against a Giants team that thrives on early aggression. The Cardinals’ bullpen has been stretched thin, and defensive lapses have cost them games, so a clean start from Pallante is critical. If the offense can replicate Monday’s timely hitting, St. Louis has a real shot to take control of the series.

Giants Suffer A Crushing Loss
The Giants dropped a tough one Monday night, falling 6–5 despite a three-run fourth inning and a late rally that came up short. Rafael Devers homered in the fifth to pull San Francisco within one, and Heliot Ramos and Patrick Bailey each drove in runs earlier in the game. Drew Gilbert added a double, but two defensive errors and missed opportunities with runners on base proved costly. The loss dropped the Giants to 77–80, matching the Cardinals’ record and further dimming their fading playoff hopes.
San Francisco has now lost four of its last five and is struggling to find consistency on both sides of the ball. The offense has shown flashes—Devers continues to mash, and Jung Hoo Lee has been a steady on-base threat—but the team ranks in the bottom third in clutch hitting and fielding percentage. The bullpen has been unreliable in high-leverage spots, and defensive miscues have compounded late-game pressure. With just five games left, the Giants need to tighten up execution if they hope to salvage a winning season.
Logan Webb takes the mound Tuesday, and he remains the Giants’ best chance at a bounce-back. With a 3.39 ERA and a reputation for inducing ground balls, Webb has the tools to neutralize a Cardinals lineup that’s been heating up. He’s gone at least six innings in 21 of his 30 starts and has held opponents to a .241 average. If Webb can get early run support and the defense holds, San Francisco has a strong shot to even the series. But given recent trends, they’ll need to play cleaner and more focused baseball to avoid another late collapse.
St Louis Cardinals vs San Francisco Giants Pick
Cardinals vs Giants Moneyline Pick
- San Francisco -1.5 (4 Units)
San Francisco -1.5 is a sharp play Tuesday night, especially with Logan Webb on the mound and the Giants looking to bounce back from a narrow 6–5 loss. Webb has been their most consistent starter all season, posting a 3.39 ERA with elite ground-ball rates and a WHIP under 1.20. He’s gone six-plus innings in 21 of 30 starts and faces a Cardinals lineup that ranks 28th in home runs and 19th in runs per game. St. Louis starter Andre Pallante has struggled with command and hard contact, allowing 18 homers and walking 47 across 134 innings. If Webb controls the tempo and the Giants avoid defensive miscues, they’re well-positioned to win by multiple runs.
Offensively, San Francisco has the tools to break this open early. Rafael Devers, Willy Adames, and Jung Hoo Lee give the Giants a balanced attack, and they’ve hit 164 homers this season—21 more than the Cardinals. St. Louis has been competitive lately, but their bullpen has blown 23 of 63 save opportunities and ranks middle-of-the-pack in inherited runner scoring rate. With playoff hopes fading, the Giants have urgency on their side and a clear edge in starting pitching, lineup depth, and late-game reliability. Laying the runline at plus money (+113) offers value in a spot where San Francisco should control both the mound and the scoreboard.
Cardinals vs Giants Over/Under Pick
- Under 7.5 (5 Units)
The Under 7.5 is a strong lean in Tuesday’s Giants–Cardinals matchup, especially with Logan Webb on the mound and both teams trending toward low-scoring outcomes. Webb has held opponents to two runs or fewer in five of his last seven starts, and the Cardinals rank bottom-five in MLB in home runs and slugging. Andre Pallante has struggled overall, but he’s capable of limiting damage when his sinker is working, and San Francisco’s offense has cooled, hitting just .234 over the past two weeks. With playoff pressure tightening execution and both bullpens showing signs of improvement, this game sets up well for a tight, low-run affair.
