Michael Lorenzen has allowed far too many baserunners and damaging hits, while his earned-run average still runs higher than the contact-based estimate. The gap is large, but the same contact profile that leaves room for fewer runs also shows why this is no clean case of bad luck.
Among pitchers who have faced at least 250 batters, the distance between his ERA and expected ERA ranks 49th in either direction, and 48 pitchers have a larger gap. The typical gap in that group is 0.51 runs; his is 2.1 times that size. That gives the Rising case a substantial discrepancy to work with. It does not make the lower estimate a forecast of what he will do next.
Over 619 batters faced this season, Lorenzen has a 7.21 ERA against a 6.15 expected ERA, a difference of 1.06 runs. The run damage has outpaced what his contact implies, but both marks describe a rough season. The gap argues that the ERA has extra weight from how the damage played out; it does not turn the underlying performance into a good one.
The latest stretch offers no relief. From September 4 through October 3, his ERA was 8.31 over 42 batters faced, still above that season expected mark. The trend leaned against the call, and the final week supplied no new evidence either way: he faced no regular-season batters from September 27 through October 3. There is no fresh outing to soften the recent run of trouble.
The contact explains why this gap deserves caution. Opponents hit .339 against Lorenzen, compared with a .300 expected average, and slugged .546 against a .493 expected mark. Those results themselves ran worse than the contact-based estimates. So the extra runs in his ERA sit on top of a hit-and-power problem, rather than a season of contact that looks harmless.
His route to limiting that damage is also narrow. A 14.5% strikeout rate and an 18.0% whiff rate leave hitters putting plenty of balls in play; he has fewer chances to end an at-bat before contact. That matters when even the expected average and slugging figures remain elevated. The figures do not identify whether sequencing, runners left aboard, defense or home runs created the added ERA gap. They do show that no single clean-contact story explains it.
The role has shifted sharply too. Toronto signed him to provide bullpen depth, then designated him for assignment; he elected free agency. That is a confirmed change in his situation, not a pitching adjustment, and it leaves his next opportunity unsettled. The first part of his Toronto stint offered length for a bullpen in flux, but a fantasy manager cannot bank on regular turns from a pitcher without a club role. For fantasy, the possible gain sits in ERA, with WHIP also helped if fewer hits reach base; the weak strikeout rate offers little support in strikeouts.
My call: ERA falls from 7.21 at the October 3, 2026 cutoff. The line is an ERA at or below 6.68 within 30 team games from October 3, 2026, counting those games alone rather than a season-to-date total. Thirty team games is about six starts for a starter, and an ERA above 6.68 breaks the call. The 0.53-run distance from his cutoff mark gives room for the rate to fall, while six starts can still turn on events beyond this argument.
Lorenzen’s run gap is real, but the traffic and weak bat-missing give it an uncomfortable foundation. Add him only in a deep league where a possible ERA improvement is worth the uncertainty of his role.
