Fantasy Baseball 2026 Week 10 Winners and Losers
Some weeks the baseball makes sense. This was not one of those weeks. The Giants hit six grand slams in 18 days, a future Hall of Famer struck out in 40 percent of his plate appearances, and a third base coach decided the rules of where he can stand were more of a suggestion. Pour yourself something and let's sort the heroes from the wreckage.
Winners
Pete Crow-Armstrong, CF, Chicago Cubs
The Cubs lost nineteen of twenty-five games and got beaten 18-3 in their own ballpark on Friday afternoon, and as he has most of the season, PCA zigged when his team zagged. PCA hit .458 with four home runs and a 306 wRC+, which means he was roughly three times better than a league-average hitter over six games while the rest of his lineup was setting itself on fire around him. His .500 isolated power was not a typo and his .429 xwOBA says the contact was real. We know PCA is a streaky hitter and if you've owned him all season, you are more than entitled to this hot stretch, and more.
Yordan Alvarez and Isaac Paredes, Houston Astros
I am cheating and giving you two, because they basically twinned this week. Alvarez hit .429 with a .551 wOBA and looked once again like the best pure hitter on the planet, posting a 260 wRC+ over six games. Paredes matched him beat for beat, going deep three times with a .550 isolated power and a 234 wRC+ of his own.
Not only that, but the teammates had identical walk rates - 15.4 percent - which was identical to their K rate of … 15.4 percent.
They drove in eighteen runs between them and dragged a team that spent May seven games under .500 back into the AL West race. If you held Alvarez through his slow stretch, this is your reward.
Matt Chapman and Willy Adames, San Francisco Giants
The Giants spent the week treating opposing pitching like a tee-ball stand. Chapman had the single best game by any hitter this season, a two-homer, eight-RBI afternoon at Wrigley that included a grand slam and put him in a club of only 121 players to ever drive in eight in a game. For the week he posted a 191 wRC+ with a .446 wOBA. Adames was even better in the aggregate, four homers and a 253 wRC+. Chapman opened the season with one homer in his first 58 games, so this is a bounce-back worth believing in. Buy the surge. Just do not pay full freight for eight RBI a day.
Losers
Juan Soto, RF, New York Mets
Here is a number that should not be possible: 18. That is Juan Soto's wRC+ for the week, meaning one of the three best hitters alive was eighty-two percent below league average over six games. He hit .120 with one RBI, zero walks, and a .190 wOBA. Soto not walking is the part that should worry you most, because the walks are the floor under everything he does. The good news is a .315 xwOBA saying the contact was not as bad as the results. This is noise, not signal. These aren't quite the dog days of summer yet, but this week for Soto was just a dog.
Mike Trout, DH, Los Angeles Angels
The strikeouts are the story. Trout punched out in forty percent of his plate appearances this week on his way to a .143 average, zero homers, zero RBI, and a 33 wRC+. A forty percent strikeout rate from a player you are starting every day is the kind of thing that quietly torches your batting average while you are not looking. His .428 xwOBA suggests the underlying contact, when he made it, was excellent, which is the only thing keeping this from being a five-alarm fire. Trout remains Trout. This week he just could not find the ball. If he gets hot this week, maybe sell high on his season-long output.
Vladimir Guerrero Jr., 1B, Toronto
Vlad's bad week was the opposite flavor of Trout's, and somehow more frustrating. He struck out only 3.8 percent of the time, so he was putting the bat on the ball constantly. He just was not doing anything with it, hitting .087 with zero homers, one RBI, and a 35 wRC+. A .221 wOBA from a first baseman you drafted for thump and average is a special kind of empty. The .280 xwOBA says weak contact, not bad luck, which is the slightly more concerning read. He is too good for this to last. He is also too expensive to bench, so grit your teeth and ride it out.
One More Thing
In the category of things I did not know were legal, we turn to Fenway Park. On June 3, during the first inning against the Orioles, Red Sox interim third base coach Chad Epperson lost sight of a Willson Contreras double down the left-field line, which is a genuine blind spot from the coach's box. Rather than guess, he simply jogged out onto the infield grass, in fair territory, to get a better look, and stood there waving Wilyer Abreu home while parked next to Baltimore third baseman Coby Mayo. Abreu was called safe, then thrown out on replay review, which means the whole adventure was for nothing.
The kicker: it was completely legal. There is no rule against a base coach wandering into the field of play like a man looking for his car in a parking lot. There should be. Until there is, expect every third base coach to start treating the infield as a suggestion.
Every season, there are days in which you see something you've never seen before in the game of baseball. This was one of those days, and if you haven't seen the play, this is now one of those days for you also:
"I don't even know if you can do that."
