The Great 2025 Matt Wallner RBI Logic Puzzle
Above are his RBI totals and his RBI opportunities relative to league average.
His OPS+ is 122 - or 22% better than average. If his RBI production matched that proportionally, we'd expect him to have about 44 RBI - 36 * 122%. That looks bad.
However, if we call RISP his RBI opportunities*, then he's only had 74 opportunities versus a league average of 95 - or 22% worse than average. Based on that, we'd expect him to have about 28 RBI - 36 * 78%. That looks good.
If we expect him to have an RBI total in proportion to his OPS+ given his opportunities, I come up with 34 RBI - 28 * 122%. Which basically brings us right back to his actual RBI total.
He really has been a human inkblot test this year. Whether you think he's coming up short of the run production a player of his caliber should be having, there's plenty of evidence of that. If you think he's being suppressed by lack of opportunity, there's evidence of that as well. Anyone can draw the conclusion they want from examining his season. He's an interesting case study of the kind of statistical profile you can have when traits are pushed to the extreme.
From looking at his Savant profile, it seems like he could greatly improve that 1st-percentile whiff rate without sacrificing too much of his immense power traits by reducing that chase rate - 41st percentile leaves quite a bit of room for improvement. If he can do that, as the great Carl Weathers once said, "Baby, we got a stew goin"
That potential alone makes him more valuable than Larnach, who is a puddle of meh pretty much across the board. Tack on age and cost, and it's no contest. Roden gets to be the puddle of meh next year while Larnach plies his trade elsewhere.
*Before you say it - yes, I know this isn't really a fully accurate picture of his RBI opportunities. A true calculation would take the expected number of RBI from each plate appearance - say, 0.4 for runners on 2nd and 3rd and nobody out, 0.06 for bases empty, etc (these figures are just for illustration, I'm both unwilling and unable to figure or find the actuals right now), sum them up, then compare that to his actual RBI total to really know how well he's doing given his opportunities.
