So, Who's Better?
Going into the 2025 season, we have Westburg slotted as the #7-ranked third baseman (with an ADP of 80). Compare that with Semien, who's #5 at 2B (ADP of 64). Based on just those full-season projections, expect Semien 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...
DFS Contests
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...
- Playing at home split alert - his career OPS when playing in front of the home crowd is .814 (.722 on the road)
- It's a day game split alert - his lifetime OPS when playing under the sun is .943 (.655 in night games)
- It's a day game - his lifetime OPS when playing under the sun is .797 (.743 in night games)
- Facing a lefty - Semien has a career OPS of .797 against southpaws (.750 vs righties)
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.
Roto Leagues
On the flip side, rotisserie is a marathon and MUCH more predictable. Most major trends tend to repeat, especially with established players.
For starters, Westburg is a 26-year old righty with the potential to produce a slash of .260/65/15/65 (BA/R/HR/RBI)... and chip in 10 swipes a year. He hits for an above-average OPS (~.770), so plenty of ways to stuff 5x5 cats. He's relatively young and his ceiling's not fully established so his projected stat levels could still shift upwards as well.
Now, with Semien - he's a 34-year old righty with .250/100/25/80 splits... and toss in 15 stolen bases a season. He should hit for an OPS of ~.750, so an above-average source of extra-base hits.He's in the second half of his career and age always wins out at some point. That could happen suddenly but higher-ranked players tend to produce a more gradual decline spread out over a few years.
Overall, when it comes down to the most common roto categories, Semien will give you a bunch more points in runs. Not a whole lot of other differences between the two.
