The San Francisco Giants open a Monday night home series against the Toronto Blue Jays at Oracle Park, with first pitch set for 9:45 PM ET on July 6, 2026. Right-hander Landen Roupp gets the ball for San Francisco against a Toronto club sending none other than Kevin Gausman to the mound — the former Giants ace who spent four seasons in San Francisco before signing with the Blue Jays. The matchup carries genuine intrigue: a rising Giants arm squaring off against one of the more familiar names to the Oracle Park faithful. Catch it on NBCS BA or KNBR 680.

Pitching Matchup: Roupp vs. Gausman

Landen Roupp continues to carve out his role in the Giants rotation. The right-hander is a product of San Francisco's player development pipeline, and every start at this point in the season is a chance to sharpen his command and prove he belongs in the back of a big-league rotation. He'll need to be at his best against a Toronto lineup that knows how to work counts and put the ball in play.

On the other side, Kevin Gausman knows Oracle Park better than just about any visiting pitcher in baseball. He posted some of the best seasons of his career in San Francisco — his 2021 campaign, when he posted a 2.81 ERA and made the NL All-Star team, remains the gold standard for what he can do. Gausman still commands a deep arsenal headlined by a splitter that gives hitters fits. Giants hitters who faced him regularly during his time in San Francisco will have a mental database to draw from, but familiarity cuts both ways.

Giants Starting Lineup Keys to Watch

• Heliot Ramos (RF, leadoff): Ramos draws the top spot in the order, putting the emphasis on his ability to get on base and set the table against a quality arm in Gausman.
• Luis Arraez (2B, No. 2): One of the hardest men in baseball to strike out, Arraez batting second is a contact nightmare for any pitcher. Gausman's splitter will get tested early if Arraez works the count.
• Rafael Devers (DH, cleanup): Devers in the four-hole brings legitimate power to the heart of the San Francisco order. His at-bats against Gausman's splitter will be a central subplot of this game.
• Bryce Eldridge (1B, No. 7): The young first baseman continues to gain experience in the lineup. Any extra-base damage he can do against a veteran arm like Gausman is a bonus.
• Casey Schmitt (3B, No. 3): Schmitt batting third signals the trust the Giants are placing in him to produce in a run-scoring spot. His plate discipline against Gausman's off-speed will matter.

Key Storyline: The Gausman Homecoming

There is no getting around it — Kevin Gausman pitching at Oracle Park as a visiting starter is a storyline. Giants fans have complicated feelings about players who leave, but Gausman's tenure here was overwhelmingly positive. The reception will likely be warm, but the Giants' lineup will not be showing any sentiment once the first pitch is thrown. Willy Adames, Jung Hoo Lee, and Victor Bericoto round out the middle and lower portion of the order and will need to find ways to get something going against a pitcher who has seen plenty of big moments.

Prediction

This one hinges on whether Roupp can match Gausman's efficiency through the first few innings. If the Giants can make Gausman work deep into counts and leverage the middle of their order — particularly Devers and Arraez — they have a path to scoring first and putting pressure on a Toronto bullpen early. Gausman is the better-established pitcher in this matchup on paper, but Oracle Park and a loud home crowd are assets. Giants take a close one, 4-3, if Roupp keeps the game within reach through five innings.
