Seattle enters this matchup analysis with a 3-2 mark over its last five, averaging 6.2 runs per game, while Cleveland has been held to just 1.4 per contest in that same span. This contrast in scoring patterns frames an MLB prediction where the Guardians’ pitching stability and situational edge at home outweigh their current offensive slump.

Team Analysis

Seattle Mariners

The Mariners sit at 72-62 with a 3-2 record in their last five games, scoring 6.2 runs per outing in that span. That production highlights occasional bursts, but their 4-6 mark across the last ten reflects inconsistency. Away from home, they carry a 31-35 record, underscoring the volatility of their offense when not in Seattle.

Cal Raleigh and Eugenio Suarez supply long-ball power, but the supporting lineup has not consistently elevated scoring in tighter contests. Julio Rodriguez adds balance yet the team’s road splits suggest diminished efficiency in run creation. With opponents containing their production in key spots, the Mariners lack the sustained rhythm to inspire confidence in this matchup.

  • WHIP: 1.26

Away Record: 31-35 • Home Record: 41-27
Last 5 Games: 3-2 (6.2 RPG)
Last 10 Games: 4-6 (5.0 RPG)


Cleveland Guardians

The Guardians are 66-66 and have gone 2-3 in their last five, producing only 1.4 runs per game. Over the last ten, they are 3-7 at 2.4 runs per game, signaling a slump at the plate. However, their home record of 33-32 indicates that despite offensive droughts, they manage to stay competitive at Progressive Field.

Jose Ramirez remains the centerpiece of Cleveland Guardians’ offense, capable of impacting games even in a low-scoring environment. Steven Kwan’s contact skills provide situational value, while Kyle Manzardo adds depth despite the team’s current cold streak. With pitching keeping them in range and a balanced home split, Cleveland is positioned to capitalize against a Mariners side that underperforms on the road.

  • Total Runs Scored: 508

Moneyline Betting Prediction

Cleveland Guardians’ season-long balance at home and ability to win tight contests offset their recent offensive slump, especially against a Mariners team that struggles away from Seattle. With Jose Ramirez anchoring the lineup and their pitching staff holding opponents in check, the Guardians are the sharper moneyline side to back here.

The Cleveland Guardians at +130 fit a live underdog profile on recent numbers.

Over/Under Prediction

In their last five, the Cleveland Guardians have produced 1.4 RPG and the Seattle Mariners 6.2. That output frames how this total sets up.

These teams are combining for 7.6 runs per game recently — below the posted total of 8.0. That points toward the Under 8.0.
