Going into the 2026 season, we have Harper slotted as the #3-ranked first baseman (with an ADP of 18). Compare that with Alonso, who's #5 at the position (ADP of 38). Based on just those full-season projections, expect Harper to be the slightly better fantasy performer. Nothing's that easy, though - let's dig into the most important stats for both daily and roto leagues...
Daily lineups are all about timing, short-term trends and matchups, even among highly-ranked players. With these two guys, keep an eye on the following splits...
On any given day, (see today's matchups) check to see how many of these OPS "bonuses" apply. If most or all are in play, highly consider going in that player's direction.
On the flip side, rotisserie is a marathon and MUCH more predictable. Most major trends tend to repeat, especially with established players.
For starters, Harper is a 33-year old lefty with the potential to produce a slash of .280/85/30/85 (BA/R/HR/RBI)... and chip in 15 swipes a year. With regard to OPS, a projected level of ~.880 means he'll inflict plenty of damage across all extra base cats.He's getting up there in age and, traditionally, most players start to slide/fall down a cliff... without much warning. So, always have a backup ready to go if things start to go south by midseason.
Now, with Alonso - he's a 31-year old righty with .240/85/40/105 splits... with virtually no SBs a season. You'll need to make up that speed gap elsewhere. OPS levels are likely to end up around ~.830, so a bunch of consistent extra-base damage. At his age, he's a legit veteran so, stat-wise, we pretty much know what to expect (or hope to get).
Overall, when it comes down to the most common roto categories, Harper gives you the edge in batting average. Not a whole lot of other differences between the two.
