Cubs vs Mariners MLB Betting Preview
The Cubs (74-55) blew an early 3-0 lead in their loss in the series opener against the Mariners on Friday. Chicago has now lost four of its last six games.
They're sending out David Peterson to the mound today. The veteran lefty made a one-inning appearance on August 17th in an extra-inning game. Previously, he was being deployed as a regular starter.
This disruption in routine could negatively affect his performance today.
The Mariners (61-68) got a much-needed win in extra innings on Friday. Their playoff hopes are hanging by a thread, as they're currently three games back of the final AL Wild Card spot.
Tonight is an exciting game for Mariners fans. After a long wait, Kade Anderson is finally making his big-league debut.
This is the undisputed best pitching prospect in baseball. He's put up video game numbers in Double-A this season after coming into the year with high expectations.
There's a good chance he gets to dominate immediately.

Cubs vs Mariners Pick, Betting Analysis
I'm going with the Mariners moneyline here.
I'm betting Seattle bats can get to Peterson, who has a 5.29 ERA and a 1.53 WHIP on the season, fresh off a one-inning appearance, which could disrupt his routine and produce negative results for this outing.
But more importantly, this is a bet on Kade Anderson. He's been absolutely dominant this season, putting up an absurd 36.6 strikeout-to-walk percentage and a 2.59 xFIP at Double-A.
Anderson was touted as a polished prospect coming out of college, and he's proven that this season.
Look for at least five dominant innings from Anderson here, which should be enough to give the Mariners the edge in this matchup.
We're getting a cheap price on the home team, making it even more appealing.
