Expert Picks, Predictions & Splits for Cubs vs Giants on Jun 13

• I am backing the Cubs on the moneyline (-127) since they have the advantage in the Cubs vs Giants pitching matchup
• The Under (8, -115) offers the best value given Cubs vs Giants‘ recent offensive metrics
• Target Ben Brown over 4.5 strikeouts (-145) against a struggling San Francisco lineup

---

The Chicago Cubs (36-34) continue their series against the San Francisco Giants (28-42) as road favorites in this late-night matchup at Oracle Park. First pitch is scheduled for 10:05 PM EST on June 13. In the previous game between these two squads, the Cubs handled business with a 5-1 victory on Friday.

The Cubs capitalized on a Michael Busch home run and a strong start from Javier Assad. The Giants’ lone bright spot was a home run from Bryce Eldridge in an otherwise quiet four-hit offensive showing.

With the Giants stepping up as the home underdog, bettors will be closely watching how elite talents like Matt Chapman, Luis Arraez, and Rafael Devers try to spark the lineup. I am looking to find an edge in the betting markets as the Cubs attempt to build momentum and push further above the .500 mark.

Cubs vs Giants Picks & Predictions

With the Cubs sending a highly effective arm to the mound against a struggling Giants lineup, the pitching matchup offers my clearest path to finding an edge. I am targeting the visitors on the moneyline. The Cubs hold a distinct advantage on the mound with right-hander Ben Brown.

Through 57.0 innings of work this season, Brown boasts a 1.74 ERA and a 0.88 WHIP. Opposing batters are hitting just .147 against him. On the other side, the Giants counter with Trevor McDonald. He has been serviceable, posting a 4.15 ERA and a 1.18 WHIP over his starts. Given the disparity in starting pitching quality, backing the Cubs to win straight up is my most logical play.

I also recommend the Under in this matchup. The Cubs feature a bullpen that has pitched to a solid 3.55 ERA this season. Combining that backend stability with Brown’s run suppression sets the stage for a quiet night from the Giants offense. The Giants hit .246 at home, and they face a starter who consistently limits hard contact.

For player props, Brown’s swing-and-miss stuff makes his strikeout prop an attractive target. I am backing Brown Over 4.5 Pitcher Strikeouts at -145 on DraftKings. He averages 9.2 strikeouts per nine innings. A baseline of 4.5 strikeouts is well within reach. If you want to back a Giants bat, Luis Arraez Over 1.5 Total Bases (+115 on FanDuel) is my preferred alternative look.

Cubs vs Giants Pitching Matchup: Ben Brown vs Trevor McDonald

The Cubs hold a distinct pitching advantage thanks to a strong season from Brown. What is most impressive about the right-hander is his ability to limit opposing lineups. His 2.24 FIP suggests his surface metrics are legitimate.

Countering for the Giants is McDonald, who has put together a respectable campaign. His 3.51 FIP indicates he has pitched better than his traditional runs allowed would imply. McDonald averages 5.57 innings per start over his last 10 outings, providing stable innings, but matching Brown’s current form will be difficult.

Cubs vs Giants: Head-to-Head Batter Matchups

Giants vs Ben Brown

Elite hitters like Chapman and Jung-Hoo Lee have yet to record a hit against Brown. The few bright spots for the Giants have come from veterans Rafael Devers and Willy Adames, who have both managed a pair of hits.

Cubs vs Trevor McDonald

Conversely, the Cubs have seen limited action against McDonald. Moises Ballesteros and Ian Happ have found success, with Happ ripping a triple in his brief history against the righty.

Cubs vs Giants: Team Stats & Betting Trends

The most glaring mismatch in this contest is the difference in run production. Despite playing on the road, the Cubs operate as a top-tier away offense, plating 4.77 runs per game. Conversely, the Giants struggle to generate offense in their own ballpark, ranking near the bottom of the league with just 3.84 runs per game.

The Cubs hold a significant edge in power and speed. The roster averages 1.17 home runs and 0.74 stolen bases per game on the road. The Giants average a sluggish 0.28 stolen bases per game at Oracle Park. Both squads share an identical 88.2 mph average exit velocity, yet the Cubs are far more efficient at translating contact into actual runs.

• The Cubs are 3-6 (33.3%) as favorites over their last 10 games.
• The Cubs are 1-0 (100.0%) as underdogs over their last 10 games.
• The Giants are 1-2 (33.3%) as favorites over their last 10 games.

Cubs vs Giants: Odds & Public Betting Splits

Odds as of June 13, 2026, at 1:00 AM ET from BetMGM.

The Cubs sit as clear road favorites on the moneyline at -127. The line is backed heavily by the betting public, who have placed 70.4% of the moneyline tickets in their favor. However, sharp money appears to be siding with the Giants at +107. Despite garnering only 29.6% of the bets, the home squad is drawing a majority 55.0% of the total moneyline stake.

Since the lines opened, the most significant movement has occurred on the game total. The run total originally opened at 7.5 but has since been bumped up to a flat 8 runs. This line movement is tied to massive betting volume on the Over, which commands an overwhelming 89.2% of the tickets and 84.6% of the betting handle.

While this ticket-to-money discrepancy on the moneyline indicates larger wagers backing the Giants, it falls just short of a definitive sharp vs public situation, according to our MLB public betting data, as the money percentage has not crossed the 60% threshold. My official prediction aligns with the majority of ticket holders in backing the Cubs. In the totals market, I am fading the heavy public action and playing the Under.

Cubs vs Giants: Injury Report

Injuries are playing a significant role in shaping the rosters and game plans as we head into this matchup. The Cubs’ injury report is heavily skewed toward the starting rotation. With established starters like Justin Steele, Jameson Taillon, and Matthew Boyd sidelined, the rotation leans on unproven talent. Any early exit from Brown would expose an overworked middle relief corps.

On the other side, the Giants are navigating a wave of injuries to their outfield. The simultaneous absences of Harrison Bader and Heliot Ramos represent a massive hit to both run prevention and run creation. Oracle Park features an expansive outfield, making Bader’s defensive absence highly impactful for a team already struggling to score runs.
