Oakland will be hoping to close the gap between itself and Houston in the American League West when it travels to Seattle on Thursday night. The Athletics are coming off a pair of wins over Los Angeles before having the day off on Wednesday. Seattle is wrapping up its series at Colorado on Wednesday—this story was published prior to the conclusion of that game.

Manaea continues consistent form

Oakland had five home games to open the second half of the season, going 3-2 in those five games. The Athletics dropped two out of three against Cleveland before winning both of their games against Los Angeles earlier this week. They blanked the Angels in a 6-0 final on Tuesday. Oakland is now embarking on a 10-game road trip that concludes in Anaheim next weekend. The Athletics are currently 3.5 games back of Houston in the AL West. They have not been great offensively, ranked No. 23 with a team batting average of .233.

First baseman Matt Olson leads the way with 96 hits and a .291 average. He has also hit a team-high 25 home runs and driven in 63 runs. Second baseman Jed Lowrie has 84 hits, while shortstop Elvis Andrus has 76 hits. They will be facing a Seattle pitching staff that is No. 19 with a team ERA of 4.43. Left-handed pitcher Sean Manaea will start for Oakland on Thursday. He allowed three runs on seven hits across 5.1 innings in his last start. Manaea has allowed three runs or less in 10 of his last 11 starts, tallying a solid 3.28 ERA this season.

Mariners coming off five-game road trip

Seattle has opened the second half of the year with five straight road games, so it will be happy to return home for this series. The Mariners took two out of three at Los Angeles last weekend before picking up a 6-4 win at Colorado on Tuesday. They went down by five runs early in Wednesday’s contest, but this story was published prior to the conclusion of that game. Seattle is 6.5 games back of Houston in the AL West, which puts them in third place. It is three games back of Oakland for the second wild-card spot. The Mariners are dead-last in the MLB with a team batting average of .220.

They are led by shortstop J.P. Crawford, who has 96 hits and a .275 average. Right fielder Mitch Haniger has 94 hits, including a team-high 22 home runs. Third baseman Ty France has 86 hits, while Kyle Seager has 75 hits. They will be facing an Oakland pitching staff that is No. 10 with a team ERA of 3.72. Right-handed pitcher Chris Flexen will start for Seattle on Thursday night. He allowed one earned run across seven innings against the Angels in his last start. Flexen has thrown at least five innings in his last seven starts, allowing no more than three earned runs in any of those outings. He has a 1.77 ERA in those 45.2 innings.

Best Bets for this Game

Full-Game Side Bet

Insiders Status:


This is a much more advantageous scheduling spot for the road team. Oakland should be well-rested after playing at home for five straight games and then having an off day on Wednesday. Seattle has played on the road for its first five games to open the second half of the season, so it will return home with some fatigue. Both of these starters have been solid, but Oakland has the more dangerous offense. The Athletics have the rest advantage and they have the better team, so this is a cheap price.

Prediction: Oakland -127

Full-Game Total Pick

Insiders Status:


These are probably two of the most consistent starters in the American League. Manaea has not allowed more than three runs in a start over the last few months and he has now gone under the total in his last four road starts. The Mariners have the worst offense in baseball, so it would be shocking if they tagged him for more than one or two runs on Thursday. They have gone under in their last five home games against a southpaw starter. Oakland has gone under in six of its last seven games against an AL West opponent.

Prediction: Under 8
