Giants vs. Orioles: Under 8.5 Is the Play as Roupp and Baz Take Center Stage on Friday
Two struggling offenses square off at Camden Yards on Friday with a pair of steady starters on the mound. Here is why the under 8.5 makes all the sense in the world in this Giants-Orioles series opener.
Friday night’s series opener between the San Francisco Giants and Baltimore Orioles at Camden Yards checks just about every box for an under. You have two pitchers who have been keeping runs off the board, two offenses that rank among the most anemic in baseball, and a game environment that should keep things quiet from the opening pitch. The total is set at 8.5 with the under priced at -105, and the case for it starts on the mound.
Landen Roupp: The Groundball Machine San Francisco Needs
Landen Roupp takes the ball for San Francisco in one of the most important roles on this Giants pitching staff. Through two starts in 2026, he carries a 4.22 ERA across 10.2 innings, though the surface number is a bit misleading. His April 4 start against the Mets was undone more by bad luck and shaky Giants defense than by bad pitching — he struck out seven in 4.2 innings and surrendered only one walk while maintaining a 1.13 WHIP on the season. Five days earlier in San Diego, he threw six shutout innings on just two hits.
What makes Roupp so well-suited for this environment is his pitch mix and overall profile. He is a groundball-heavy sinker pitcher who generates weak contact and keeps the ball in the ballpark. Over the last two seasons, he has maintained a groundball rate above 46 percent, and in 2026 he has yet to allow a home run across 10.2 innings. His sinker, which averaged 92.8 mph last year, reportedly jumped to 94.6 mph this spring — a notable velocity uptick that should make it even harder to elevate against him. He pairs it with a sharp curveball that generates swings and misses and a changeup he can use to neutralize both sides of the plate.
Roupp’s career ERA of 3.76 undersells how dominant he can be when in form. During a strong stretch last summer, he posted a 1.15 ERA over the better part of a month and ranked third in baseball among qualified starters. A pitcher who generates this many grounders at Camden Yards — which plays neutral early in the season before the heat sets in — is exactly the type you want anchoring an under bet.
Shane Baz Settling In Nicely for the Orioles
Shane Baz came to Baltimore this offseason after four seasons in Tampa Bay, arriving with a career 4.25 ERA and a reputation as a high-strikeout right-hander still working toward his ceiling. His 4.87 ERA in 2025 with the Rays was not pretty, but it masked a 9.5 strikeout rate per nine innings and a 2.8 strikeout-to-walk ratio that shows the stuff is still legitimate. His best stretch — a 3.06 ERA across 14 starts in 2024 — offered a glimpse of what he can look like when it is all clicking.
Through two starts in Baltimore, Baz has been more than serviceable. He gave up four runs in 5.1 innings against Minnesota in his debut, then bounced back with a quality start in Pittsburgh on April 4, allowing just one run over 5.2 innings with five strikeouts. His ERA sits at 3.27 with a 1.18 WHIP across 11 innings, and he has yet to surrender a home run. The fly-ball tendency that has haunted him at times in his career is worth monitoring, but Camden Yards in early April is not the same park it becomes in July, and his ability to rack up strikeouts means he can get through lineups without leaning too heavily on his defense.
One small flag: Baz has been vulnerable against left-handed batters early this season, who are hitting .391 against him in the limited sample. The Giants do carry some left-handed bats, but the San Francisco lineup as a whole has been too cold to capitalize on any individual weakness.
Two of Baseball’s Worst Offenses Set Up the Under Perfectly
The pitching matchup alone makes a compelling case for the under, but the offensive context seals it. The San Francisco Giants currently rank dead last in baseball in batting ratios, hitting just .218 as a team with a .578 OPS through 11 games. They have scored only 30 runs across those 11 contests — fewer than three runs per game — and they have done it despite carrying several high-profile bats who have yet to wake up. Harrison Bader is hitting .114, Jung Hoo Lee is at .143, Patrick Bailey is at .129, and Rafael Devers has managed just a .220 average with an ugly strikeout-to-walk ratio. The Giants have racked up 90 strikeouts against only 27 walks in the early going, a sign that opposing pitchers are attacking this lineup with confidence and getting results.
The Baltimore Orioles are not much better. Sitting at a .242 team batting average with a .692 OPS — 26th in baseball — Baltimore has scored 45 runs across 12 games, roughly 3.7 per game. The Orioles have punched out 116 times while drawing 48 walks, a ratio that signals a lineup pressing for production it has not yet found. Taylor Ward is the one legitimate bright spot at .383 with a 1.038 OPS, and Gunnar Henderson has four home runs. But Pete Alonso is hitting .188, Samuel Basallo is at .167, and Coby Mayo is at .133. This is not a lineup positioned to hang a crooked number against a sinker-heavy groundball pitcher.
Baltimore’s recent scoring history reinforces the trend further. In their last five games the scores have been 2-1, 4-2, 5-3, 2-8, and 2-3 — only one of those five games came anywhere near the 8.5 threshold, and that was a loss. The Giants just threw a 6-0 shutout against Philadelphia on April 8. Quiet baseball is the pattern, not the exception, for both of these clubs right now.
Best Bet: Under 8.5 (-105) (Fanatics)
Every component of this matchup is pointing the same direction. Roupp’s groundball-heavy sinker profile suppresses hard contact and limits big innings. Baz has been steady in his first two outings and has kept the ball in the park entirely. The Giants rank last in the majors offensively and have been held to three runs or fewer in game after game. The Orioles are not far behind them in their offensive struggles, and their recent scoring patterns mirror what the total is projecting for Friday night.
Neither bullpen projects as a wildcard either, with both clubs relatively fresh heading into this one. There is no obvious reason to expect the late innings to suddenly blow the game open. At -105, you are getting the under at essentially even money in a matchup where the starters, the offenses, and the recent scoring trends are all aligned. Take the under 8.5 in Baltimore on Friday.
