Braves vs Mariners MLB Betting Preview
Atlanta Braves Betting Preview: Lineup Hides the Flaws
Following Tommy John surgery in 2023, former first-round selection JR Ritchie surged through the Braves system in 2024 and 2025. After starting the season with a 0.99 ERA across 27 and 1/3 innings in Triple-A, Ritchie earned his first big league start on April 23rd.
Ritchie's big-league career has started in excellent fashion, as after his initial two starts he holds an ERA of 2.92, and the Braves have won both outings. While he's been fantastic where it counts, Ritchie's underlying profile is much less convincing, and achieving a comparable level of success could be more difficult as the league becomes more familiar with his arsenal.
Ritchie holds a strikeout-minus-walk rate of 9.8, a whiff rate of 19.5%, and a chase rate of 25.5%. He's been hard-hit 41.2% of the time and generated ground balls just 35.3% of the time, yet currently holds a BABIP below the marks he achieved in Triple-A this season and in 2024.
The Braves will be without Ronald Acuña Jr. in this matchup, but the depth of their lineup has been excellent thus far, and with an OPS of .740, Acuña is far from the reason for their offensive dominance.
Atlanta currently ranks first in baseball with a wRC+ of 124, first in slugging rate by a considerable margin, and third in expected slugging rate. They have struck out just 19.6% of the time and rank behind only the Dodgers in hard-hit rate.
Seattle Mariners Betting Preview: Better Than It Looks logo1url=
The Mariners have dropped off offensively relative to last season thus far, as after finishing third in wRC+ in 2025, Seattle currently ranks ninth with a wRC+ of 101. It holds the eighth-lowest BABIP and ranks 21st in expected batting average.
Seattle hit righties more effectively last season with a wRC+ of 114 and holds significantly better splits versus RHP this season, with a wRC+ of 110. It also ranks fifth in hard-hit rate versus RHP.
After four straight high-quality seasons, Gilbert, seemingly out of the blue, had a fairly average start to the year. He's pitched to an ERA of 4.03, and while his xERA of 3.76 and xFIP of 3.57 suggest he is due for improved results, they also suggest he has not been as dominant as we have typically seen.
Gilbert has not been overly efficient of late and, over his last three outings, has recorded an average of 14.3 outs. His K-rate is down to 24.4% this season, and he has had issues throwing competitive pitches in put-away counts of late.
Braves vs Mariners Pick, Betting Analysis
While the Mariners do strike out at a fairly high rate, they have hit right-handed pitching quite effectively once again this season and seem likely to have a solid day at the plate versus Ritchie.
Ritchie has struck out 8.03 batters per nine throughout his first two big-league starts, has generated little swing-and-miss, and is not forcing batters to chase very often. His walk rate and hard-hit rates are also concerning, and things may not get any easier as teams become more familiar with his stuff.
So, while the Mariners are an appealing candidate for any starter to rack up strikeouts, Ritchie's chances of exposing the Mariners in that regard seem overvalued given his overall profile at the big-league level thus far.
At a price of +102, there looks to be strong value in backing Ritchie to record fewer than 4.5 strikeouts in this matchup.
Pick: JR Ritchie Under 4.5 Strikeouts (+102) (FanDuel, Play to -110)
