The Seattle Mariners continue to surprise and will seek yet another upset win when they clash with the Boston Red Sox in the third of a four-game series Saturday afternoon from Fenway Park. The Mariners have Chris Flexen on the hill and the Red Sox will send Nathan Eovaldi to the mound. The Mariners tallied a 7-3 win in Thursday’s series opener, and the Red Sox answered with a 6-5 win on Friday.

Flexen Squanders 10 hits, Mariners Pitching Thrives

The Mariners will give Chris Flexen the nod on Saturday. Flexen evaded danger in his latest effort, conceding just one run on a whopping 10 hits in six innings against the Astros in a tough 1-0 loss. The young right-hander has fared well in two of his three performances this season and has registered a 3.38 ERA and a 1.63 WHIP accompanied by a 1-1 record in 16 innings. This will mark his first career meeting against the Red Sox.

Seattle has to be pleased with its results thus far. They have been competitive against strong opponents and held the potent Dodgers' offense to only a total of four runs in two games earlier this week before limiting Boston to just three runs in Thursday’s series opener.

The Mariners are glad to welcome Kyle Lewis back from the IL. The 25-year old right fielder made his season debut earlier this week after winning the 2020 AL Rookie of the Year. Lewis launched 11 home runs along with 28 RBI’s and a .801 OPS in 2020 and is 0 for 7 at the plate in his first two games of this season.

Seattle is averaging 4.26 runs per game, ranking them 16th in the big leagues. They own a solid 3.80 team ERA, good for 11th overall.

Eovaldi Registers Win, Red Sox Cool Down

Red Sox ace Nathan Eovaldi will start this one. Eovaldi wasn’t at his best last time out, squandering four runs on nine hits in 6.1 innings against a good White Sox lineup, resulting in an 11-4 win. The veteran right-hander is having a terrific season, posting a 3.04 ERA and a 1.06 WHIP complimented with a 3-1 record in 23.2 innings of work. Eovaldi has yielded decent results in his four career meetings against the Mariners, filing a 4.09 ERA in 22 innings.

Boston has cooled down after their big winning streak earlier in the month, especially from an offensive standpoint however they remain in the top spot in the AL East and it’s safe to say this team is going to score a ton of runs. They tallied one win in two games against Toronto this week, and have lost two straight bouts heading into Friday night.

Xander Bogaerts continues to come up huge at the dish, launching two big flys along with four RBI's in his last three clashes entering Friday night. The 28-year old slugger is flaunting a dazzling .371 average along with eight RBI’s and a .970 OPS. Bogaerts went 1 for 5 in the series opener.

The Red Sox rank second overall with an average of 5.30 runs per game on the season. They feature a 3.83 team ERA, good for 12th in the big leagues.

Best Bets for this Game

Full-Game Side Bet

Insiders Status:


This particular matchup comes down to the starting pitching. Seattle has Chris Flexen on the mound and the right-hander was lucky to only allow one run after squandering 10 hits against the Astros last time out. He has not been able to have consistent success as he owns a terrible 7.18 career ERA in over 80 career innings.

Furthermore, Nathan Eovaldi has been reliable through four starts, holding his foe to two or fewer runs in three of his four performances. Seattle’s offense has cooled down as well. They rank last in team batting average and 27th in OPS.

Prediction: Boston Red Sox -1.5

Full-Game Total Pick

Insiders Status:


The Red Sox offense should bring this total over. Boston continues to lead the way in average and is second in the Majors in OPS. This Red Sox team is feasting on right-handed pitching this season. Flexen was good in his first start but has since given up 18 runs in his last 11 innings. The over is a perfect 8-0 in the last 8 meetings between these foes entering Friday.

In addition, while I expect Eovaldi to neutralize Seattle, they should be good for a few runs. Eovaldi has recorded a 4.09 ERA in 22 innings against this Mariners team. The over is 8-2 in the Red Sox’ last 10 games as a favorite.

Prediction: Over 9

Full-Game Prop Bet

Insiders Status:


The Red Sox offense should have another big game. Boston features a stellar .862 OPS along with a .299 average against right-handed starters this season. Flexen has not been as sharp as the right-hander's ERA indicates plus he gave up six runs in his only road start of the season.

Prediction: Red Sox Team Total Over 4.5

First Five Innings Prop Prediction

Insiders Status:


I am taking the Red Sox to score first. Seattle has only scored a combined nine runs in the first two innings in their 19 games on the season. The Red Sox should get to Flexen for early offense. Also, Eovaldi has only conceded one run in the first two innings this season.
