Seattle Form & Recent Results

Seattle heads into this matchup trying to bounce back after a recent rough couple of games. The Mariners are currently on a one-game losing streak and had lost three of their last five games going into Friday’s game. Those defeats came in a few different spots, including a home loss to the Athletics, a road loss to the Red Sox in Boston, and another road defeat against the Blue Jays in Toronto. Their most recent setback came Thursday at home, when they fell 7-4 to the Athletics. Even in the loss, Julio Rodriguez still found a way to contribute for Seattle, finishing 1-for-4 with a double, a walk, a run scored, and two RBI. The Mariners’ pitching staff had some trouble staying fully in control in that game as well, issuing three walks, which gave the A's extra chances to put pressure on them.

This season, Randy Arozarena has been one of the biggest offensive pieces for Seattle. He leads the team with 22 home runs and also sits at the top of the Mariners’ RBI leaderboard with 66 runs driven in. Arozarena has also been Seattle’s most consistent hitter in terms of batting average, carrying a .273 mark so far this year. Dominic Canzone has provided additional power in the lineup as well, ranking second on the team with 21 home runs. As a group, though, the Mariners will need to tighten things up on the mound if they want to get back in the win column. Seattle has allowed an average of 6.4 runs per game in their last five, a number they will definitely want to bring down as they look to take advantage of a home matchup against a struggling Athletics club.

Athletics Form & Recent Results

The Athletics head into Saturday night's matchup against the Mariners riding a bit of momentum after stringing together back-to-back victories. However, that recent success only tells part of the story, as the team has actually stumbled in three of their last five games leading up to Friday's action. Those recent setbacks include a pair of tough road losses against the division-rival Rangers down in Arlington, alongside a frustrating home defeat at the hands of the Orioles. They managed to bounce back beautifully during Thursday's road trip, securing a hard-fought 7-4 victory over the Mariners. In that contest, left fielder Zack Gelof sparkled by going 2-for-5 at the plate, coming up huge with a single, a home run, two runs scored, and an RBI. On the mound, reliever Jack Perkins put together a wild but effective three-inning performance, where he surrendered four hits and three earned runs while racking up an impressive seven strikeouts, despite battling his control with five walks. As a whole, the A’s offense was absolutely firing on all cylinders, exploding for fourteen hits, including two home runs, to accumulate twenty-two total bases. Meanwhile, the pitching staff completely overpowered Seattle's hitters by racking up a staggering eighteen combined strikeouts and throwing one hundred nineteen strikes, while giving up nine hits along the way.

Looking at the bigger picture for this season, a couple of key power hitters have been carrying the offensive load for the A's. Catcher Shea Langeliers currently anchors the lineup as the team's top home run threat, having already blasted twenty-three long balls over the wall this year. Right behind him is rookie first baseman Nick Kurtz, who has provided incredible protection in the lineup by launching twenty-one home runs of his own so far. Kurtz has also proven to be the A’s most dependable run-producer, pacing the entire ballclub with sixty-nine RBIs on the season. They will need all the run support they can get right now, because the pitching staff has been going through an incredibly rough patch lately. Over their last five games alone, the Athletics' defense and pitching have surrendered an alarming average of six runs per game. As they prepare to take the field again in Seattle on Saturday night, the A's are desperately hoping their arms can find their rhythm, turn things around, and lock down a much-needed victory on the road.
