Did The Brewers Just Get A More Versatile & Potent Version Of Andruw Monasterio?

All that those three signings secured the Crew was a top-of-the-rotation arm, a Gold Glove-finalist center fielder, and a valuable utility player who was a serviceable third baseman for a team that won the NL Central Division championship. The Brewers may have done something akin to those signings again.

The Overview Of Offense
Anthony Seigler is a former first-round pick in the 2018 amateur draft who left the Yankees in minor-league free agency. His offensive profile points to excellent on-base skills and some pop while also flashing some speed on the base paths. His major weakness has been hitting for average.

The switch-hitting Seigler’s on-base ability is the most notable item of his profile: in 2022 and 2023, his walks exceeded his strikeouts (144 to 132), while he also flashed some power (33 doubles and 11 home runs) over 465 at-bats. In addition to the power, Seigler added 23 stolen bases while he was caught stealing a dozen times.

In 2024, Seigler posted 64 walks to 77 strikeouts in 364 at-bats at Double-A Somerset while delivering 24 doubles and 12 home runs. Siegler added 29 steals in 32 attempts, with his baserunning going up a notch.

The low strikeout rate and speed suggest that his low batting average (never higher than .236 since the pandemic) is due to bad luck rather than poor decisions. This is a bat that could break out, or at least be very solid, with either some luck or a little coaching.

Defensive Details
On defense, Seigler is very intriguing. He spent most of his minor-league career (through 2023) as a catcher before making a Craig Biggio-esque move to second base after some very limited time in both corner outfield spots. At second base, he made 15 errors in 118 games. He also saw some additional playing time in left and right field.

Seigler’s defense at catcher was solid, even as he may have had some issues throwing out runners (the highest caught-stealing percentage since the 2019 minor-league season was 24%). He was otherwise solid, much like current Brewers farmhand Wes Clarke, who also has seen time behind the plate in the minors.

Seigler’s move to second points to an ability to play other positions. His arm could possibly handle third base, where the Brewers are looking for an immediate solution. At the same time, Brock Wilken, Mike Boeve, Luke Adams, and Eric Bitonti are top prospects with experience at the position.

The Andruw Monasterio Match-Up
In one sense, Seigler is like Monasterio, who was signed as a minor-league free agent before the 2022 season. He had solid seasons and made his way to Milwaukee in 2023, where he performed well as the team’s third baseman down the stretch with his contact-hitting skills and ability to hit left-handers.

While he hasn’t seen much action at the variety of infield positions as Monasterio, he has extensive experience at catcher and he did play both corner outfield positions very briefly. If Seigler can handle additional infield positions, like third base and first base, he could be a valuable asset with his switch-hitting.

Seigler’s Likely Status
Seigler appears ticketed for Triple-A Nashville in 2025, where he could continue some of his breakout in 2024 with Double-A Somerset for the Yankees. But there is an off chance he could beat out Oliver Dunn and Tyler Black for a spot on the Brewers’ bench, given his experience at catcher and the likelihood that William Contreras could see time at DH to give him semi-days off from the wear and tear behind the plate.

Given the Brewers’ financial uncertainty due to the collapse of the Bally sports networks and the shift to MLB streaming for their local broadcast options, the team can’t win bidding wars to attract free agents. The almost certain departure of Willy Adames is another example.

But if Seigler can become another Monasterio, Perkins, or Myers, then the Brewers can certainly improve their odds of being competitive.
