Over/Under Betting Trend Could Affect Cubs vs Mariners Prediction

The Seattle Mariners will square off against Chicago Cubs' lefty Jon Lester on Wednesday night. While Lester has been dominant this season, to the tune of a 2.37 ERA and 19 Ks in 19 innings, one early-season Mariners' trend indicates that it could be a higher-scoring affair than expected.

Typically, when two teams send starting pitchers to the mound with sub-3.00 ERAs – Mariners' starter Marco Gonzalez has a 5-0 record and 2.80 ERA – you get a close, low-scoring contest. But when the Mariners face a left-handed pitcher this season, the over has hit a perfect six out of six times.

The over has been a good bet, in general, for those handicapping Mariners' games this season, as it has hit in 22 of their 29 contests. But for the total to hit the over in every game that Seattle faced a lefty during a calendar month, that's a trend worth keeping an eye on. And the over/under total for tonight's game is at nine runs, according to FanDuel Sportsbook.

Seattle's tendency to play in these high-scoring games may be a surprise to those who haven't followed the team closely this season, but the Mariners are ranked No. 2 in MLB in runs scored per game (5.91). They also give up almost that many runs per contest to their opponents, at 5.50 runs per game. And nine of the last 10 Mariners' games have seen at least nine runs scored.

With two potent offenses – the Cubs rank No. 3 in the Majors at 5.52 runs per game – and a betting trend pointing you toward the over, it wouldn't be out of the question for at least 10 runs to hit the board on Wednesday night in Seattle.
