The New York Yankees will look to stay hot when they host the Seattle Mariners at 1:05 pm ET Saturday in the middle game of a three-game series at Yankee Stadium.
The Yankees (60-49) are on a four-game winning streak and have won seven of their last eight games and nine of their past 11. New York’s 18-8 record since July 6 is the best in MLB and the Yankees are big favorites Saturday.
The Mariners (58-53) have lost three games in a row and seven of 10.

New York Yankees | -210 | -1.5 (-115) | Under 10 (-110) |
Odds as of Aug. 6th at DraftKings.
The Yankees opened at -180 on the moneyline and those odds quickly went up. The weather forecast calls for partly sunny with a high of 87 degrees and winds south from 6-13 mph.
Probable Pitchers
The Mariners will give the ball to Chris Flexen (10-5, 3.75) while recently acquired Andrew Heaney (6-8, 5.42) will start for the Yankees.
Flexen ended a two-start losing streak Monday by beating the Tampa Bay Rays on the road. He went 6.2 innings and scattered seven hits while allowing two runs, striking out six and walking two.
Flexen vs Heaney
10-5 | Record | 6-8 |
3.75 | ERA | 5.42 |
4.16 | xERA | 4.40 |
1.25 | WHIP | 1.31 |
3.13 | SO/W | 3.77 |
Flexen is 5-2 with a 2.92 ERA in his last 10 starts after spending last season in the Korean Baseball Organization. He has recorded quality starts in 10 of his 20 outings and the Mariners are 14-6 when he pitches.
Flexen their muscle. 💪

On the road, Flexen has a 4-1 record but a 5.44 ERA. He is 2-0 with a 3.50 ERA in three starts in day games.
Despite spending parts of three seasons with the Mets from 2017-19, Flexen will be making his first career appearance against the Yankees.
Heaney had a rough debut with the Yankees on Monday at home against the Baltimore Orioles after being acquired from the Los Angeles Angels in a trade. He gave up four runs and six hits in four innings while striking out four and walking none.
The Yankees went out and got Andrew Heaney at the deadline and nobody is talking about it. Big boost. https://t.co/36J127USBV

Heaney is 2-5 with a 6.92 ERA in his last eight starts. He has had quality starts in just seven of 19 rotation turns.
Oddly, Heaney has started only one day game all season, getting a win against the Boston Red Sox when he allowed three runs in 5.1 innings.
Heaney has struggled against the Mariners this season, losing both starts and getting tagged for eight runs in 7.1 inning. In his career against Seattle, Heaney is 3-6 with a 4.28 ERA in 14 starts.
Haniger Hits Heaney
Mariners right fielder Mitch Haniger has had success against Heaney, going 8 for 20 (.400) with one double, one triple and three home runs. Utility player Dylan Moore is 5 for 11 (.455) with two doubles and one homer.
Yankees left fielder Joey Gallo has struggled against Flexen as he is 1 for 11 (.091) with five strikeouts.

Many scouts have long felt Heaney’s lackluster results have not matched up with his above average talent. Perhaps that will start to change now that he is with the Yankees.
Heaney seems like a worthwhile play against Flexen, who struggles away from Seattle.
Pick: Yankees -210
