The Mariners head to Houston for the last time this season.

MLB: Houston Astros at San Diego Padres Orlando Ramirez-USA TODAY Sports

It wasn’t comfortable by any means, but the Mariners sweep of the Diamondbacks was pure Chaos Ball. It took two extra-innings victories and a pair of three-run bombs from Kyle Seager, but they took care of business in the desert. They’ve pushed ahead of Oakland in the standings and are actually just 4.5 games behind Houston. Taking the division is a pipe dream of course, but Seattle now has the ninth best record in the major leagues and a better record than the Braves and Padres, two teams in the National League currently holding playoff spots.

The Mariners have 75 wins in the bank and trail the Red Sox by three games. Let’s assume Boston goes 12-11 over their remaining 23 games — not a ridiculous assumption based on their schedule and the COVID issues wreaking havoc on their roster. That means the Mariners need to win 16 of their remaining 25 games to tie the Red Sox for the second Wild Card spot. Essentially that means they can afford just a single series loss for the rest of the season. That gives them a tiny bit of wiggle room as they head into what’s probably their hardest series of their remaining schedule.

If there’s one thing that should give the Mariners a bit of hope, it’s that the Astros have continued to struggle a bit during the stretch run. After getting shut out twice in Seattle, they traveled to San Diego over the weekend and lost two of three, including a walk-off loss on Sunday afternoon. They scored a total of eleven runs in three games as their offensive struggles continued in Southern California. Of course, they also have the fifth best home record in baseball and crushed the Mariners the last time they visited Houston.

Jake Meyers CF R 91 0.436 129 1.2
Martín Maldonado C R 361 0.228 70 -4.7

The Astros got Chas McCormick back from the Injured List last week and they’ve decided to platoon him and Jake Meyers in center field. They’re both right-handed so it won’t follow a traditional split of playing time. McCormick is probably the better hitter but Meyers is the more dynamic fielder and runner. They also signed Marwin Gonzalez after Boston cut him loose a week ago and called up old friend Jose Siri when rosters expanded. Yordan Alvarez tweaked his knee on Saturday while playing the outfield in San Diego; x-rays came back negative and he made a pinch-hit appearance on Sunday, but it’s possible he won’t be swinging at 100% during this series.

From a previous series preview:

Remember a few years ago when Lance McCullers’s success was built on throwing his curveball nearly half the time? After missing the entire 2019 because of Tommy John surgery, his pitch mix has changed drastically. He’s throwing his curveball just 20% of the time now and he’s introduced a slider to his repertoire to give him another breaking ball to keep batters off balance. His strikeout rate is as good as ever because all four of his pitches are running whiff rates north of 30%. That’s just around league average or slightly above for his three secondary offerings but a 30% whiff rate on his sinker is elite. He’s struggled a bit with his command this season, but all those strikeouts and an above average groundball rate have helped him mitigate all those extra base runners.

This will be McCullers fourth start against the Mariners this season. He’s allowed six runs across 17 innings in those three starts. His last time out in Seattle, he went five scoreless innings, though he wasn’t that sharp. He allowed four hits and walked three while only striking out three.


RHP Jake Odorizzi

From a previous series preview:

After signing with Houston in late March and getting off to a delayed start to the season, Jake Odorizzi hasn’t found the success he enjoyed in his breakout 2019 season in Minnesota. He looks a lot like the mid-rotation starter from his days with the Rays earlier in his career. His strikeout rate has fallen to its lowest point since an abbreviated cup of coffee back in 2013. And with a batted ball profile that skews heavily towards fly ball contact, a significant home run problem has resurfaced after he was able to get it under control as a Twin. The biggest issue in his pitch mix is a splitter that just isn’t running the same kinds of whiff rates he saw with it earlier in his career.

Odorizzi was the tough luck loser in his last outing in Seattle. He pitched into the sixth inning, leaving the game with two runners on. The winning run came around to score later on that inning and Odorizzi was saddled with the loss.


RHP José Urquidy

IP K% BB% HR/FB% GB% ERA FIP
IP K% BB% HR/FB% GB% ERA FIP
81 2/3 21.8% 4.4% 11.3% 31.2% 3.42 3.91

Four-seam 54.7% 92.5 2205 112 92 92

Curveball 6.0% 76.7 2546 109
Slider 21.3% 79.3 2472 91 87 89

José Urquidy had been sidelined with a shoulder injury since late June before making his return from the Injured List against the Padres over the weekend. He threw 71 pitches and pitched into the fifth inning, allowing just two runs. Prior to his injury, he had been in the middle of a solid bounce back season after some COVID issues had derailed his sophomore campaign in 2020. An elite walk rate and a flyball-heavy batted ball profile has helped him post an ERA a half run below his FIP. His strikeout rate sits below average despite a good riding fastball and a trio of solid secondary offerings. This season, he’s dropped the usage of his curveball down to just 6% while bumping up the number of sliders in his pitch mix. That slurvy offering has produced better results than his slower curveball so optimizing its usage gives him a higher ceiling.

The A’s really fell apart against the Blue Jays over the weekend. On Friday, Marcus Semien blasted a three-run, walk-off home run against his former team. The next day, a five run ninth inning made the 10-8 final score a lot closer than it should have been. They were shutout 8-0 in the final game of the series on Sunday. They’ve won just six of their last 20 games and have finally fallen behind the Mariners in the standings. They return home on Tuesday to face the White Sox while the Blue Jays travel to New York to face the Yankees four times this week. New York lost their second series in a row to the Orioles over the weekend. The Red Sox won twice against Cleveland, with a walk-off win on Saturday securing the series; they host the Rays for three games to start the week.
