The Seattle Mariners (35-32) look for a third straight win over the Baltimore Orioles (31-36) tonight, as the two teams continue their series at Oriole Park at Camden Yards. First pitch is scheduled for 6:35 pm ET, with Seattle listed as short road favorites in the MLB odds. As of early Wednesday afternoon the MLB weather data looks dicey, with the possibility of thunderstorms in the forecast.

In their last game, the Mariners earned a tight 6-5 win over Baltimore. Seattle produced a strong offensive showing with 11 hits, powered by home runs from Mitch Garver and Randy Arozarena. Baltimore tried to answer with a late homer from Coby Mayo, but ultimately fell short on the scoreboard.

For this matchup, I am looking for value in all sports betting markets. Below, you’ll find my favorite player prop picks and predictions for the Mariners vs Orioles on June 10th.

Before we dive into a prediction for a side or total, let’s first examine the MLB props market. Seattle starter George Kirby averages exactly 6.0 innings per start, but he is not an overpowering strikeout pitcher. He produces just 7.39 strikeouts per nine innings. In a standard six-inning outing, that rate translates to roughly 4.9 strikeouts. With his K prop set at 5.5, the under provides a solid edge.

At the dish, Julio Rodríguez enters this matchup with a .761 OPS and 13 home runs per the MLB batter vs pitcher stats. I trust his ability to find extra-base damage and clear 1.5 total bases as a central piece of Seattle’s offense in this game.

On the Orioles side, Pete Alonso leads Baltimore with 41 RBIs and 13 home runs this season. Despite Seattle’s strong pitching, backing the home team’s top run producer at +135 to record an RBI offers good value in the heart of the order.

To find value in this matchup, I am focusing heavily on the pitching. Although Baltimore starter Brandon Young owns a respectable 3.47 ERA, the overall pitching edge in the MLB starting lineups leans strongly toward the visitors. Seattle’s pitching staff has posted an excellent 3.48 ERA, well ahead of the Orioles’ inflated 4.62 mark.

That gap becomes even more obvious in the late innings. Seattle’s bullpen has been reliable, carrying a 3.20 ERA and a 1.31 WHIP. By contrast, Baltimore’s relievers have consistently struggled to close games, recording a 4.65 ERA. Because of that major advantage in run prevention, my favorite pick is the Mariners moneyline.

George Kirby vs Brandon Young Stats

StatisticGeorge Kirby (SEA)Brandon Young (BAL)
W-L Record5-54-1
ERA4.043.47
WHIP1.281.34
FIP3.404.28
K/97.396.75
BB/92.083.10
Opponent AVG.272.257
IP/Start6.005.48

Kirby’s surface-level 4.04 ERA is somewhat misleading. His 3.40 FIP indicates he has pitched better than his ERA suggests, with some bad luck on balls in play (.323 BABIP). Kirby does an excellent job limiting walks with a 2.08 BB/9 rate, though he has allowed more contact over his last 10 starts.

Young, meanwhile, has been a pleasant surprise with a 4-1 record. However, his 4.28 FIP is nearly a full run higher than his ERA, suggesting possible regression. He relies more on generating contact than overpowering hitters, posting just 6.75 K/9 along with an elevated 3.10 BB/9.

Team ERA3.48 [5th]4.62 [25th]
Team WHIP1.18 [4th]1.41 [25th]

The Mariners are an elite run-prevention team, ranking in the top five in both ERA and WHIP across the league. That stands in stark contrast to Baltimore’s pitching staff, which ranks 25th in both metrics.

Baltimore partially offsets that weakness with its explosive home offense. The Orioles become a top-five attack in front of their fans, averaging 4.97 runs per game. They make consistent hard contact, with an average exit velocity of 88.9 mph, which supports confidence in power bats such as Alonso.
