Kenny Ducey’s Mariners vs Athletics Preview
Seattle Mariners Betting Preview
Bryan Woo has delivered the goods once again in his third big-league season. He's running another incredibly low walk rate at 4.8% while maintaining a strong 24.3% strikeout rate, and he's doing what every Mariners pitcher has been known to do in the last five or so years which is to induce a whole bunch of fly balls into that forgiving Seattle air.
The results have been good, and the .231 Expected Batting Average backs them up; it's incredibly hard to build a rally off of Woo. He's sporting a pretty high .390 Expected Slugging, which is considerably ahead of his career average, but that's going to happen when you do nothing but pitch to contact in the air.
It's somewhat terrifying to take that approach into what's essentially a Triple-A park in Sacramento, but the good news is that Woo has been nails since the start of June. He came home with a .223 xBA last month and owns a .206 xBA in July, and best of all the xSLG has come down to .309 this month.
Now, the schedule has been somewhat light, but Woo has still had to square up the Yankees and Astros in two of his four starts this month. He did allow seven runs (six earned) across those two meetings, surrendering two homers to Houston in Seattle, but the strikeout numbers remain solid and the metrics would back up that Woo's contact has been friendly overall.
Athletics Betting Preview
Jeffrey Springs, meanwhile, has been something of a mystery. He's more or less stabilized after a terrible start to the season, finishing April with a 6.04 ERA and bringing that back down under four runs briefly this month, but his xBA has spiked to .280 in July with a disastrous .503 xSLG representing by far his worst part of the year.
What we don't like to see is that Springs has yet to flash his high strikeout upside at any point this year. His whiff rate did briefly hit 28.7% in June — a fine mark — but his strikeout rate hasn't cracked 21% in any month and for the season, his 18.9% clip is six points under his career average.
We have an extreme fly ball pitcher here who's at the very least done a good job of throwing strikes, but his home park — and an unfortunate reduction in swings and misses — have made a once-promising left-hander into a liability.
Crucially, Springs owns a 4.27 ERA in nine home outings versus a 4.01 ERA in 13 away games, giving up 11 of his 20 homers in Sacramento. That illustrates just how dangerous he's been to the Athletics' success when pitching to fly balls in his home park.
Mariners vs Athletics Prediction, Betting Analysis
The Athletics are a team that is more or less built around driving the ball, so it's no surprise that they rank first in OPS against fly-ball pitchers as opposed to 14th in the reverse split. Seattle has traditionally been similarly constructed, but sits 17th against fly-ball arms as opposed to sixth when meeting a ground-baller.
That puts us in a very prickly position here. Springs isn't a guy I love to trust — particularly at home — but Seattle is ice cold at the moment with a 78 wRC+ to rank dead last in the game over the last two weeks, coming along with a poor .126 Isolated Power and a loud 25.7% strikeout rate.
The Athletics have hit for a ton of power with a .228 ISO, and rank top-10 in wRC+ over that same span with the fourth-best home run-to-fly ball ratio in the game during that span, and while Woo has been lights out, he does stand to be a bit liable to longballs here in a challenging park for pitchers like him. On top of that, it's not like the Athletics' strikeout rate has been dreadful, either, staying more or less steady at 23.1%.
I am a big believer in this offense, and I don't think either man is going to have a particularly rosy time out there in arduous conditions where the ball's going to fly. I'll stick with the red-hot Athletics to steal one at home.
