2026 Fantasy Baseball Week 4 Buy Low, Sell High: Trade for Jac Caglianone, Flip Oneil Cruz, Andy Pages
Welcome to our weekly 2026 Fantasy Baseball Buy Low, Sell High column. We will help you identify the top 2026 fantasy baseball trades to make in any given week. We’re going to outline three buy-lows and three sell-highs for Fantasy Baseball Week 4.
The key here is that we’ve carefully selected these recommendations to make sure that they’re reasonable. I’m not going to suggest that you buy low on a superstar who is off to a slow start, because it’s highly unlikely your leaguemate will accept an offer like that. The same goes for sell-highs: they won’t be obvious regression candidates.
With that in mind, find out why I’m buying low on Michael Harris II, Jac Caglianone, and Jesus Sanchez, while selling high on Oneil Cruz, Andy Pages, and Brendan Donovan.

2026 FANTASY BASEBALL WEEK 4 BUY LOW TARGETS
Michael Harris II (OF – ATL)
Michael Harris II is off to an underwhelming start, slashing .235/.264/.373 with two home runs and one stolen base in 53 plate appearances.
But he’s showing excellent batted ball metrics so far, as highlighted by a 17.1% barrel rate, which ranks in the 91st percentile, per Baseball Savant. Harris has also displayed elite bat speed at 75.1 MPH (88th percentile). In other words, the power surge could be coming soon.
Given that Harris got off to an abysmal start last year and has gained a reputation as a super streaky player, you may be able to acquire him at a discount.
Jac Caglianone (1B, OF – KCR)
Jac Caglianone continues to struggle at the plate, slashing .229/.315/.313 with zero home runs in 54 plate appearances. But there are some encouraging signs with his batted ball metrics and bat speed.
I’m still a big believer in Caglianone due to his prospect pedigree. You also have to like that he’ll be hitting at Kauffman Stadium, where the fences have been moved in.
So far, that hasn’t translated into more home runs, but it’s only a matter of time before the ball starts flying out of that park. Buy Caglianone before that happens.
Jesús Sánchez (OF – TOR)
Jesús Sánchez hasn’t done anything notable so far this season, slashing .273/.327/.477 with two home runs in 49 plate appearances.
But the biggest key here is that since the Blue Jays are depleted with injuries, including George Springer, Addison Barger, and Alejandro Kirk, Sanchez has been bumped up to the cleanup role. Hitting behind an on-base machine like Vladimir Guerrero Jr. can do wonders for Sanchez’s RBI total.
There’s a chance that Sanchez is available on your waiver wire. If not, you can likely trade for him at a reasonable price. Do so before he gets hot.
2026 FANTASY BASEBALL WEEK 4 SELL HIGH PLAYERS
Oneil Cruz (OF – PIT)
Before diving into why I view Oneil Cruz as a sell-high, let me preface this by saying I’m still high on him for the entire year. This may just be the perfect moment to try to trade him for a more established star who is off to a slow start.
Perhaps you can package Cruz with a pitcher like Emerson Hancock and a closer like Jakob Junis to acquire someone like Ronald Acuña Jr. Coming off a game where he stole three bases and another where he homered, the time is right.
Cruz similarly got off to a hot start last year, putting up a 142 wRC+ in March/April. There’s a chance that this is merely a hot streak.
With that said, I would only move him for a premium bat.
Andy Pages (OF – LAD)
Andy Pages is currently slashing .429/.467/.714 with four home runs and two stolen bases in 60 plate appearances. The 25-year-old outfielder is likely to be a strong contributor all year long.
However, he’s more of a rock-solid bat than one with elite upside, as he’s showing now. The batted ball metrics are merely decent, including a 9.5% barrel rate and a 109.1 MPH maximum exit velocity.
This is a hitter who can provide 25 homers with 10 stolen bases, but now might be the time to cash in.
Brendan Donovan (2B, 3B, OF – SEA)
Brendan Donovan is slashing .293/.412/.561 with three home runs in 51 plate appearances. It’s an unprecedented power surge for the 29-year-old veteran, as he came into this year with a career-high of 14 homers.
But this is “smoke and mirrors” as they say, as it’s not backed by an improved barrel rate, since that currently sits at 6.3%, which is actually a decline from last year (8.8%).
Perhaps someone in your league believes that Donovan can get to 20+ home runs. I don’t buy it.
I’d look to sell Donovan for a middle infielder with more upside, one who hasn’t done much just yet. Ceddanne Rafaela makes a ton of sense, since he also has some positional versatility, just like Donovan.
Summary: 2026 Fantasy Baseball Buy Low Sell High (Week 4)
Although the season is young, savvy 2026 Fantasy Baseball managers are already plotting the right trade strings to pull. Making the right 2026 Fantasy Baseball Buy Lows and Sell Highs this early can be a massive advantage.
As such, buying low on Michael Harris II, Jac Caglianone, and Jesus Sanchez could land you some undervalued production before they heat up and hit their true ceilings. Meanwhile, Oneil Cruz, Andy Pages, and Brendan Donovan could all be peaking, and make strong sell highs.
