Angels Notes: Detmers, Further Additions, Anderson

With the Angels’ recent signing of left-hander Yusei Kikuchi to a three-year deal now officially announced, GM Perry Minasian spoke yesterday to reporters (including Jeff Fletcher of the Orange County Register) about the club’s 2025 rotation and their plans for the rest of the winter.

Of note, Minasian suggested that with the addition of Kikuchi and fellow offseason addition Kyle Hendricks to the club’s rotation mix, the Angels currently have those two veterans, Tyler Anderson, and Jose Soriano penciled into the first four spots in their rotation for 2025. Notably, that leaves left-hander Reid Detmers fighting for a spot in the rotation alongside less established arms like Chase Silseth and Jack Kochanowicz. 2024 was a brutal season for Detmers, as the lefty surrendered a disastrous 6.70 ERA across 17 big league starts.

Weak as that production was, however, Detmers’s underlying metrics suggest his performance may have been slightly better than it looks on paper. His 27.9% strikeout rate was actually the best of his career, while his 9.7% walk rate was certainly elevated, but more or less in line with his 2023 performance. Detmers’s 4.72 FIP was “just” 13% worse than league average by measure of FIP-, and some metrics were even more bullish on his underlying numbers. His 3.86 xFIP was actually 6% better than league average, and a 3.77 SIERA actually places Detmers 43rd among 138 starting pitchers who threw at least 80 innings out of the rotation this past season.

While underlying metrics that compared Detmers to Corbin Burnes (3.75 SIERA) and Gerrit Cole (3.79 SIERA) in 2024 certainly don’t tell the whole story by themselves, they do provide enough optimism about Detmer’s future that it’s a surprise to hear he isn’t guaranteed a rotation spot next year. After all, the lefty posted a solid 4.15 ERA and 3.97 FIP across 53 starts in 2022 and ’23, and is just a few years removed from being the Halos’ first-round draft pick when they selected tenth overall in 2020. With that being said, it’s easy to imagine Detmers’s performance after coming back to the majors back in September raising red flags in the front office’s mind. While he struck out an eye-popping 34.2% of opponents in five starts down the stretch, he also struggled badly with the long ball, surrendering 8 homers and an untenable 15.6% barrel rate.

Minasian also didn’t rule out making further additions to the club’s rotation. “We’ll continue to look, from a free agent standpoint, from a trade standpoint,” he said, as relayed by Fletcher. “If there’s an upgrade, from a rotation standpoint, we’ll look to do it.”

With that being said, it seems as though upgrades to the rotation may take a backseat to upgrading other areas of the roster as the Angels look ahead to the remainder of the winter. Specifically, Minasian noted that they’d like to add depth to their bench and bullpen while focusing on lengthening the lineup with another bat. The club has already added Jorge Soler as an everyday DH and Travis d’Aranud poised to act as a backup to Logan O’Hoppe behind the plate, but holes remain in a lineup that posted just a 90 wRC+ that was 25th in baseball last year.

Nolan Schanuel, Luis Rengifo, and Zach Neto figure to have regular roles on the infield, with Schanuel in particular seemingly locking up first base. Neto is sure to be the everyday shortstop when healthy, but he could miss the start of the season after going under the knife earlier this month. Kevin Newman and Scott Kingery have already been brought in to shore up the club’s infield depth on the bench, but another infield bat could help lessen the club’s reliance on oft-injured Anthony Rendon while also backing up Neto early in the season.

There’s also room in the outfield for another bat. Taylor Ward figures to be the club’s everyday left fielder, and Mike Trout will of course be an everyday player in the outfield when healthy enough to take the field. Mickey Moniak and Jo Adell currently figure to platoon in right field when everyone’s healthy, but upgrading that spot in the lineup could improve the roster, particularly if the addition was capable of playing center at least occasionally to lessen the defensive workload on Trout.

One other possibility Fletcher floats is the Angels considering a trade of Anderson. Anderson came up in the rumor mill ahead of the trade deadline over the summer, but no deal ultimately came together as the Angels reportedly preferred to hold onto players controlled beyond the 2024 season. Given that hesitance just a few months ago, it’s unclear if trading Anderson is something the Halos would seriously consider this winter, and it would hardly be a surprise to see him stay put.

The veteran southpaw is entering the final year of his contract with the Angels in 2025 following a decent season in 2024 where he posted a solid 3.81 ERA despite lackluster peripherals. Even if clubs project him to post numbers closer to his 4.66 FIP and and 4.37 xERA next year, his ability to eat innings (179 1/3 frames across 31 starts in 2024) could make him an attractive back-of-the-rotation candidate to teams in need of pitching and a deal would clear the final year and $13MM of his contract off on the Angels’ books to address other areas of the roster.

Of course, moving Anderson would be a step backwards in terms of depth for an Angels club that has already parted ways with Griffin Canning and Patrick Sandoval this winter. Removing Anderson from the club’s rotation would leave them with Kikuchi, Hendricks, Soriano, and Detmers as their front four starters with Kochanowicz, Silseth, and depth options like Sam Aldegheri in the mix for the fifth spot. With that being said, it’s at least plausible the club could listen to offers on him if they were to land a third external starter to join Kikuchi and Hendricks in the Anaheim rotation next year, whether that be in trade or free agency.
