MLB Predictions and Picks: Our 3 Best Bets for September 1, 2026

Get today's top MLB best bets and predictions for Tuesday, Sept 1 — three picks covering a total, a moneyline, and a run line across the slate. Get today's top MLB best bets and predictions for Tuesday, Sept 1 — three picks covering a total, a moneyline, and a run line across the slate.

The best record in the National League walks into Wrigley Field tonight, as Milwaukee visits a Cubs club that just hung 17 runs on them in the series opener. That headliner anchors a full Tuesday board built almost entirely around pitching. A veteran ace makes a West Coast start against a last-place lineup, a rookie makes his debut in a bandbox, and a division race simmers in Chicago. The market has already told a story on several of these games, with one total sliding a run and a half before first pitch. The playoff races are tightening across both leagues as the stretch run heats up. Below are three plays worth a look: an early-window total that the books have hammered down, a primetime moneyline on a road favorite priced like a dog, and a late West Coast run line behind an ace. We break down each one before revealing the side.

Early Game — Seattle Mariners at Boston Red Sox

This one opened with a total near nine runs and has since been slashed to seven. That kind of move gets attention. Seattle sends Bryan Woo to the mound, and the right-hander carries a 9-9 record with a 4.36 ERA and 142 strikeouts. He is the reason the number dropped. Boston counters with rookie Jedixson Paez, a 22-year-old making his Red Sox debut after a brief earlier cameo with the White Sox as a Rule 5 pick.

Paez arrives with strong minor league marks, including a 4.11 ERA across Double-A and Triple-A and a 74-to-7 strikeout-to-walk ratio. At Triple-A Worcester he posted a 2.92 ERA. Still, a debut start in a hitter’s park brings real variance. The context also cuts against the low number. These teams combined for 17 runs in Monday’s 9-8, extra-inning opener. Seattle sits at 64-74 and closed August with five straight losses, while Boston is 75-63 and fighting for a Wild Card spot.

The Pick: Under 7.0 Runs (+105)

The case for the under starts with Woo and price. He owns a mid-4.00s ERA but misses bats, and Seattle’s offense is ice cold. A frigid road lineup facing a quality arm should not push many runs across. Getting plus money on the under after the number already fell is the value here. The case against is straightforward. Fenway is a hitter’s park, Boston’s bats are rolling, and a debuting rookie can unravel quickly. If Paez labors early, seven runs disappears fast. For our full Mariners-Red Sox breakdown, we still lean to the quieter script and take the under.

Mid-Day Game — Milwaukee Brewers at Chicago Cubs

This is the marquee matchup of the night. Milwaukee owns the best record in the National League at 85-53 and leads the NL Central. Chicago sits second at 78-60 and remains firmly in the playoff picture. The Cubs also sent a message in Monday’s opener, rolling to a 17-3 win that snapped Milwaukee’s momentum. The Brewers had won seven of ten entering the series.

The pitching edge, on paper, belongs to Chicago. Cubs lefty Matthew Boyd brings an 8-3 record and a 3.99 ERA. Milwaukee counters with lefty Robert Gasser, who sits at 4-5 with a 4.59 ERA. That gap is why the home side is favored. Even so, the Brewers have been the more complete team all season, and their lineup and bullpen depth travel well on the road.

The Pick: Milwaukee Brewers Moneyline (+111)

Getting the league’s best team at plus money is the draw. Milwaukee has outperformed its rotation names all year through defense, baserunning, and relief work. A road dog price on the NL’s top club invites value, especially after a lopsided loss that may have inflated the market’s read on Chicago. The case against is the arm gap. Boyd has been the steadier starter, and a lefty who limits damage can neutralize a deep lineup. Milwaukee also just absorbed a 17-3 beating, so a flat night is possible. We accept the risk and back the Brewers to win outright.

Late Game — New York Yankees at Los Angeles Angels

New York Yankees vs. Los Angeles Angels — Time & How to Watch

WhereAngel Stadium, Anaheim CA
WhenTuesday, September 1 – 9:38 PM ET
TVYES Network / KCOP 13

The pitching mismatch here is the story. New York hands the ball to Gerrit Cole, who owns a 3.19 ERA with 105 strikeouts and a 7-7 record that undersells his season. The Angels send Grayson Rodriguez, who has struggled to a 6.03 ERA and a 4-5 mark. New York enters at 78-60 and chasing in the AL East. Los Angeles sits at 53-85 and long out of the race.

The talent gap is stark, and the market knows it. New York’s moneyline has climbed as money poured in on the road favorite. The upside for the Angels is Mike Trout, who remains healthy and has 20 home runs. One swing can flip a low-scoring game. Still, Cole against a bottom-tier lineup, opposite a starter allowing six runs per nine, is exactly the profile bettors chase in September.

The Pick: New York Yankees Run Line -1.5 (-110)

Laying the run and a half makes sense with Cole on the mound against a poor offense and a struggling starter. New York should generate early scoring off Rodriguez, and a multi-run cushion is the likely path. The plus-money moneyline juice at -195 also makes the run line a better value on price. The case against is baseball’s coin-flip nature. Even lopsided matchups produce one-run games, and Trout can single-handedly keep it close. A late Angels rally or a quiet Yankees night against a shaky bullpen would sting. For more, see our Yankees-Angels preview. We still lay the run line.

Today’s MLB Best Bets Recap

Three plays, three bet types. We take the under seven runs in Seattle at Boston, back the Brewers moneyline on the road in Chicago, and lay the Yankees run line against the Angels in Anaheim. Each carries clear two-way risk, so shop the price and bet responsibly.
