The Mariners (64-74) are sinking fast, losers of five in a row, and they are now 10 games below .500. Their playoff hopes are fading, as they are now in third place in the AL West, six games out of the top spot and 5.5 games out of the last AL Wild Card.
The Red Sox had lost two in a row before winning the opener of this series 9-8. While 7.5 games out of first place in the AL East, they own the second Wild Card.
Hard Rock Bet Sportsbook has the Red Sox as the slight Game 2 favorites, posted at -115, with the Mariners at +110 and a total of 7.5 runs.
Much Better than a Near No-Hitter, but 8 Runs Still Not Enough
In the opener of this series, the Mariners’ lineup was solid, but their pitching was not, as they fell 9-8 in 10 innings; in the previous game, they were shut out and had only one hit. In the loss in Game 1, Randy Arozarena had a big game, going 4-for-5 with a home run and four RBIs; Cal Raleigh hit a solo home run, and Dominic Canzone had two RBIs.
This season, Seattle ranks dead last in baseball in runs scored and 18th in team ERA. The Mariners have given up an average of 6.8 runs per game in their five-game skid.
Arozarena (.274, 21 home runs, 62 RBIs) leads the club in batting average, RBI, and home runs, and he had been in a slump with three hits and no RBIs in six games before the last one. Canzone (.255, 20 home runs, 61 RBIs) ranks second in RBIs and tied for second in home runs, and while he only batted .232 last month, he has five RBIs over the last five games.
While the M’s have four players with at least 20 home runs, they not only rank last in runs scored but also in team batting average (.227) as well.
Seattle's Starter for Game 2
Bryan Woo (9-9, 4.36 ERA, 1.10 WHIP) gets the call for the Mariners and was tagged for six runs in four innings in his last start in a 6-0 loss to the Philadelphia Phillies. He has been streaky as of late, giving up six runs in his last outing, only two in three starts before that, and then five in each of his previous two starts before that. This season, Woo has pitched 142 1/3 innings, struck out 142 batters, and walked 30.
Boston Lineup Wakes Up
After only totaling three runs in two losses, the Red Sox lineup woke up in the opener of this series. Trevor Story played the hero with a walk-off game-winning single in the 10th inning; he and Ceddanne Rafaela each had three RBIs, and Jarren Duran and Mickey Gasper each had home runs.
Boston ranks a solid fourth in the Majors in team ERA, but 17th in runs scored. In their four losses in their last six games, they only totaled three runs, while totaling 15 runs in the two wins.
Willson Contreras (.274, 26 home runs, 79 RBIs) leads the Sox in home runs and RBIs and is out for this game on the 10-day IL.
Rafaela (.284, 16 home runs, 70 RBIs) is the clubhouse leader in batting average, is tied for second in RBIs, and had slumped at the end of last month before a solid Game 1 of this series.
The Red Sox have taken three of four games against the Mariners this season.
Boston's Starter for Game 2
As of Tuesday morning, the Red Sox have not named a starter for this game.
Mariners vs. Red Sox Prediction
Red Sox Moneyline Hard Rock Bet, -115
The Red Sox have good home value in this game as a slight favorite, even though they have not named a starter as of Tuesday morning. They won the opener of this series against a slumping Mariners’ team that has lost five in a row, where they gave up an average of 6.8 runs per game. On top of that, Seattle starter Woo has been inconsistent in his last few starts and gave up six in his last one.
Boston will get the W in the second game of this series and go for the sweep tomorrow.
