Seattle Mariners @ Baltimore Orioles Preview

The Seattle Mariners, currently holding a strong 66-53 record, arrive in Baltimore as one of the hottest teams in baseball, riding a seven-game winning streak and boasting a 9-1 record over their last ten outings. They are 29-28 on the road this season. The Mariners' offense has been potent, ranking third in the league with 171 home runs, led by Cal Raleigh's league-leading 45 blasts and Eugenio Suárez's 37. Their pitching staff has also been solid, with a 3.81 ERA, ranking tenth in MLB. Right-hander Logan Gilbert (3-4, 3.35 ERA) is slated to start for Seattle.

The Baltimore Orioles, with a 53-65 record, are looking to snap a two-game losing streak and improve their 28-29 home record. They sit fifth in the AL East. The Orioles' offense has struggled recently, accumulating only 12 hits in their last three-game series against the Athletics, a concerning trend for interim manager Tony Mansolino. Despite their power numbers (11th in HR with 144), key players like Gunnar Henderson, Jackson Holliday, and Jordan Westburg will need to step up. Left-hander Trevor Rogers (5-2, 1.44 ERA) will take the mound for Baltimore. The Orioles are also dealing with a significant injury list, including Zach Eflin, Félix Bautista, Grayson Rodriguez, Kyle Bradish, Tyler Wells, Albert Suárez, Maverick Handley, Gary Sánchez, Jorge Mateo, and Cody Poteet on the IL. Notably, Tyler O'Neill (right wrist inflammation) and Colton Cowser (concussion) are out.

Pick: Under 8.5 Total Runs

widget-odds-mlb-ou-11921-SEA-BAL

Despite Oriole Park at Camden Yards being slightly batter-friendly with a higher home run factor (108), the current form of both teams' offenses and the pitching matchup lean towards a lower-scoring game. The Baltimore Orioles' offense has been in a slump, managing only 12 hits in their last three games. While the Mariners' offense is strong, they face Trevor Rogers, who has been exceptional recently with a 1.44 ERA and a low 3.2% HR/FB% over 62.1 innings. Logan Gilbert, for the Mariners, also brings a solid 3.35 ERA to the mound. Both teams have shown a tendency for lower-scoring games, with the Orioles hitting the under in 39 of 65 home games this season, and the Mariners hitting the under in 24 of 57 away games. The previous game between these two teams on August 12 also went significantly under the total, ending 1-0. Given these factors, the Under 8.5 total runs is the favored pick.

Top Player Prop Picks

Randy Arozarena Over Total Bases

widget-props-mlb-11921-6242536

Mariners outfielder Randy Arozarena has an excellent historical matchup against Orioles pitcher Trevor Rogers. In 6 plate appearances against Rogers, Arozarena has recorded 3 hits, including 2 home runs, leading to a .500 batting average, a 1.500 slugging percentage, and a .807 wOBA. This indicates a strong comfort level and success against Rogers' pitching. Furthermore, Oriole Park at Camden Yards has a park factor of 108 for home runs, suggesting a favorable environment for power hitters. While Arozarena's season HR% is 4.5%, his specific history against Rogers makes him a prime candidate to exceed his total bases prop.

Ryan Noda Over Total Bases

Orioles first baseman Ryan Noda has demonstrated significant success in his limited appearances against Mariners pitcher Logan Gilbert. In 5 plate appearances, Noda has collected 2 hits, including a double, resulting in a .500 batting average, a .750 slugging percentage, and a .564 wOBA. These are very strong numbers, indicating Noda's ability to make solid contact against Gilbert. Given the Orioles' need for offensive production and Noda's favorable individual matchup, he is well-positioned to contribute with extra-base hits and go over his total bases prop.

Logan Gilbert Over Strikeouts

Mariners pitcher Logan Gilbert has a favorable strikeout matchup against the current Baltimore Orioles roster. In 27 plate appearances against Orioles hitters, Gilbert has recorded 9 strikeouts, translating to a 33.3% strikeout rate. Several Orioles players have struggled with strikeouts against Gilbert, including Gunnar Henderson (3 K in 6 PA, 50% K%), Ryan Noda (2 K in 5 PA, 40% K%), Jordan Westburg (2 K in 3 PA, 66.7% K%), and Greg Allen (1 K in 2 PA, 50% K%). Gilbert's season strikeout rate is 35.1%, and the Orioles as a team rank 21st in MLB in strikeout percentage (8.62%), indicating they are prone to striking out. This combination of individual matchups and team tendencies makes Gilbert a strong candidate to exceed his strikeout total.
