2026 Fantasy Baseball Week 5 Buy Low, Sell High: Trade for Fernando Tatis Jr., Flip James Wood, Ian Happ

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 5.

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. But if I do, I’ll be sure to have a reasonable trade offer for you to send.

With that in mind, find out why I’m buying low on Fernando Tatis Jr., Kyle Manzardo, and Trent Grisham, while selling high on James Wood, Jake Burger, and Ian Happ. Remember, buy lows *need* to come at discounts, while sell highs *must* get you more than you would have before the season.

2026 FANTASY BASEBALL WEEK 5 BUY LOW TARGETS

Fernando Tatis Jr. (OF – SDP)

Fernando Tatis Jr. is off to a disappointing start, slashing .253/.340/.304 with zero home runs and six stolen bases in 95 plate appearances.

However, there are reasons to be encouraged. For one, Tatis has a .384 xwOBA, which is much higher than his .300 wOBA. In other words, he’s hitting the ball hard, but not getting results yet. We see this reflected in his 14.5% barrel rate (86th percentile) and 67.7% hard-hit rate (100th percentile).

Then, you have to consider that Tatis has two starts at second base, which was a pleasant surprise. If he can get eligibility at second base, that would be absolutely huge. I’d try to ship James Wood for him, throwing in a minor asset (perhaps a lower-tier closer) to sweeten the deal.

Kyle Manzardo (1B – CLE)

Kyle Manzardo is currently slashing .180/.265/.246 with one home run in 68 plate appearances. The plate discipline has been horrendous (7.4 BB%, 36.8 K%), but the batted ball metrics have been decent (11.1% barrel rate).

This putrid start makes it very easy to acquire Manzardo in a trade. There’s even a chance that he’s available on your waiver wire.

What I like about buying him is that he’s showing signs of coming out of his slump, hitting safely in seven of his last eight games. He’s currently putting up a 74th percentile average exit velocity.

Remember, Manzardo hit 27 home runs with a 113 wRC+ in his age-25 season last year. Perhaps this is just a slow start.

Trent Grisham (OF – NYY)

Trent Grisham currently has a .167/.321/.348 slash with three home runs and one stolen base in 81 plate appearances. However, the plate discipline looks great (18.5 BB%, 17.3 K%), as do the batted ball metrics (57.7% hard-hit rate). We saw signs of him snapping out of his slump.

Grisham has three homers in his last six games, including two dingers against the Angels on April 13th.

Let’s not forget that Grisham hit 34 home runs last year. There’s power in this bat, and you have to love the team context with the Yankees.

James Wood (OF – WSH)

James Wood is off to a terrific start, slashing .247/.380/.551 with seven home runs and four stolen bases in 108 plate appearances. You have to love the batted ball metrics, including a video game-like 27.8% barrel rate.

I definitely see the appeal with Wood, who has some of the loudest tools in the league and is still only 23 years old. But the same issue that caused a late-season slump is still there, even during this current hot streak. Wood has a 32.4% strikeout rate.

That means we’re going to continue to see Wood go on dry spells at some point throughout the year.

With that in mind, why not try to ship Wood for Tatis, since the latter still hasn’t homered? You might have a chance to pull that one off.

Jake Burger (1B – TEX)

Jake Burger is in the middle of a bounce-back season, slashing .250/.280/.466 with five home runs in 93 plate appearances. This is a 30-homer hitter who you got for cheap in drafts.

While I still like Burger for the rest of the season, the plate discipline metrics are concerning, including a 3.2% walk rate and a 31.2% strikeout rate.

That means that a slump could be coming soon. We could be at the start of one, as he’s 0-for-9 in his last two games.

Ian Happ (OF – CHC)

Ian Happ is off to a rock-solid start, slashing .240/.352/.533 with six homers in 88 plate appearances. The barrel rate looks terrific at 18.8%.

However, the strikeout rate is concerning at 30.7%, which means that we could see a slump coming soon. Plus, we know who Happ is at this point. He’s your classic well-rounded outfielder who hits about 25 homers with 8-10 steals.

I find it unlikely that he’s having a power surge at 31 years old.

With that in mind, I’d see if you can trade Happ for Trent Grisham plus another asset, perhaps like another low-end reliever.

Summary: 2026 Fantasy Baseball Week 5 Buy Low Sell High
