The Seattle Mariners and Baltimore Orioles close their four-game series Thursday night at Oriole Park at Camden Yards. First pitch is scheduled for 7:05 PM ET, with national coverage on ESPN and MLB.TV. Seattle enters at 36-33 and still holds first place in the AL West, while Baltimore is 32-37 and fourth in the AL East.
Seattle leads the series 2-1 after winning the first two games, but Baltimore answered with a 7-2 win Wednesday. Brandon Young threw seven scoreless innings, Pete Alonso homered, and Jackson Holliday broke the game open with a grand slam. The Mariners were held to four singles, while George Kirby struck out 10 but received little offensive support.
Bryan Woo starts for Seattle against Kyle Bradish. Woo is 5-4 with a 3.74 ERA, 1.00 WHIP, 75 strikeouts, and only 14 walks over 77 innings. Bradish is 3-7 with a 3.89 ERA, 1.51 WHIP, 68 strikeouts, and 36 walks across 69.1 innings. That command gap is the biggest separator in a matchup priced close to even.

Seattle Mariners vs Baltimore Orioles Odds
These are the current betting lines for Thursday’s series finale. With both teams sitting in a tight moneyline range and the total at 8.5, bettors should keep monitoring the latest MLB odds before first pitch.
| Team | Moneyline | Run Line | Total |
|---|---|---|---|
| Seattle Mariners | -116 | -1.5 (+141) | O 8.5 (-110) |
| Baltimore Orioles | -105 | +1.5 (-170) | U 8.5 (-110) |
Seattle Mariners Betting Form
Seattle had a flat offensive night Wednesday, but the larger form is still solid. The Mariners won Monday 6-3, won Tuesday 6-5 in 10 innings, and still have a chance to take three of four on the road. Wednesday’s loss was more about Brandon Young controlling contact than a complete collapse, although being held to four singles does highlight how much the lineup misses Cal Raleigh and J.P. Crawford.
The Mariners are not a high-average lineup, batting .237 as a team, but they have hit 87 home runs and own a .396 slugging percentage. Randy Arozarena is batting .294 with a .380 on-base percentage, while Luke Raley leads the club with 13 homers. Julio Rodríguez, Josh Naylor, Arozarena, Raley, Dominic Canzone, Mitch Garver, and Patrick Wisdom give Seattle enough power to respond quickly if Bradish falls behind in counts. Bettors comparing Seattle’s offense with the rest of Thursday’s slate can review the broader MLB game previews.
Woo gives Seattle the cleaner starting-pitcher profile. His 1.00 WHIP is excellent, and his 75-to-14 strikeout-to-walk ratio gives him a clear path to controlling Baltimore’s lineup without putting extra runners on base. The Orioles can hit for power, but Woo’s ability to limit free passes matters at Camden Yards, especially against a lineup that just showed how quickly one swing can change the game.
Seattle’s bullpen should also be in decent shape because Domingo González handled the final innings Wednesday after being recalled from Triple-A. That protected some of the higher-leverage arms after the game got away. The Mariners still need cleaner middle relief than they received Wednesday, but Woo’s workload profile gives them a reasonable chance to shorten the game.
Baltimore Orioles Betting Form
Baltimore finally stopped its four-game losing streak Wednesday and did it in a way that could carry over. The Orioles produced 11 hits, received two-hit games from Alonso, Leody Taveras, and Tyler O’Neill, and got a major swing from Holliday. It was not just the grand slam. Baltimore put pressure on Kirby for several innings before finally breaking through in the sixth.
The Orioles are hitting .241 with 80 home runs and a .400 slugging percentage. Alonso leads the club with 14 homers and 42 RBIs, while Taylor Ward owns a .406 on-base percentage. Gunnar Henderson, Jackson Holliday, Colton Cowser, Coby Mayo, Tyler O’Neill, and Blaze Alexander give Baltimore real upside, but the offense can still become too dependent on home runs and extra-base contact. The daily MLB picks and predictions board can help bettors compare Baltimore’s short home-underdog price with the rest of the card.
Bradish has the surface ERA to keep Baltimore in this game, but the WHIP is a problem. He has allowed 69 hits and 36 walks in 69.1 innings. That means traffic, and traffic against Seattle’s power profile can turn into crooked innings even if Bradish limits hard contact for stretches. His 68 strikeouts show the swing-and-miss is still there, but the command has not fully matched the raw stuff.
The Orioles also have lineup questions behind the plate. Adley Rutschman and Samuel Basallo are both listed day-to-day, and their availability matters against Woo. Baltimore already has enough inconsistency in the order, so missing one or both catchers would reduce the club’s depth and on-base quality.
Seattle Mariners vs Baltimore Orioles Matchup Breakdown
The starting-pitcher edge leans Seattle. Woo and Bradish have similar ERAs, but Woo’s WHIP, walk rate, and strikeout-to-walk profile are much cleaner. Bradish can miss bats, but he has allowed too many baserunners to be priced almost evenly against a Seattle team that can punish mistakes with one swing.
Seattle’s offensive profile is built for this matchup. The Mariners do not need 12 hits to win. They need Bradish to walk one hitter before Raley, Rodríguez, Arozarena, Naylor, Garver, or Wisdom gets a mistake in the zone. That is why Bradish’s 1.51 WHIP is so important. Baltimore can survive singles. It is harder to survive free passes in front of power.
Baltimore’s path is forcing Woo into the stretch early. Alonso, Henderson, O’Neill, Cowser, and Holliday can all elevate fastballs, and Camden Yards will play warm Thursday night. If the Orioles make Woo work and get into Seattle’s middle relief by the sixth, the underdog price becomes more attractive.
The bullpen comparison is close but slightly favors Seattle because of the way Wednesday unfolded. Baltimore used Yennier Cano for 1.1 innings to finish the win, while Seattle let González absorb the late damage. Young’s seven-inning start also protected most of Baltimore’s bullpen, so this is not a major fatigue spot either way.
Weather leans toward offense but carries delay risk. Baltimore is forecast around 88 degrees at first pitch, with thunderstorms possible near 7 PM and again around 9 PM. A delay after the game begins would raise bullpen exposure and make the full-game total more volatile. Without a delay, the heat helps the ball carry, but Woo’s command still gives Seattle the better pitching foundation.
This is the type of matchup where an MLB betting guide approach matters. The ERAs are close, but the underlying baserunner profile is not. Woo’s command gives Seattle more ways to control the first six innings, while Bradish has to pitch through more traffic against a lineup with real power.
Seattle Mariners vs Baltimore Orioles Predictions and Best Bets
I lean toward Seattle on the moneyline. My projection makes the Mariners closer to a -130 favorite, which leaves value at -116. Woo has the better WHIP, better walk profile, and more reliable path through the lineup. In a near coin-flip market, that matters.
Baltimore is live because Wednesday’s win was convincing. The Orioles got contributions from the bottom and middle of the order, and Bradish has enough swing-and-miss stuff to keep Seattle quiet if his slider is sharp. I still do not want to back a pitcher with a 1.51 WHIP at this price against a team with 87 home runs.
The total leans Over 8.5, but it is not my preferred bet. Baltimore’s lineup woke up Wednesday, Seattle’s power should match up well with Bradish’s traffic issues, and the warm weather helps. The concern is Woo. If he works six strong innings, the Orioles may need late runs to push the game over the number.
The run line is tempting at plus money, but this series has already produced two competitive games and Baltimore’s offense may have regained some confidence. The moneyline is the cleaner position because it targets the starting-pitching edge without needing Seattle to win by margin.
My projected score is Mariners 5, Orioles 4. Bettors comparing this matchup with other premium MLB picks should keep Seattle playable through about -130.
Best Bet: Mariners Moneyline -116.
