Brandon Eisert may have been optioned just as quickly as he was called up, but his profile is still interesting to look at.
On Monday, the Toronto Blue Jays added 26-year-old left-handed pitcher Brandon Eisert to the 40-man roster and added him to the active roster. He made his big league debut on Monday, pitching two innings with three walks but no runs allowed, before being sent down on Tuesday.
However, if there’s one thing Brandon Eisert has been since the Blue Jays selected him in the 18th round of the 2019 draft out of Oregon State, it’s consistent.
Eisert didn’t make his professional debut until the 2021 season, first pitching two games with the Dunedin Blue Jays where he struck out 38.5% of the batters he faced in three innings. His first real stop was in Vancouver with the Canadians, posting a 4.05 ERA and a 3.96 FIP in 46.2 innings pitched, along with a 29.6 K% and a 7.9 BB%.
Towards the end of the 2022 season, Eisert earned a promotion to Double-A New Hampshire, where he had a 2.63 ERA and a 1.47 FIP in 13.2 innings pitched with the Fisher Cats, along with a 30.9 K% and a 3.6 BB%. Through the three levels, Eisert had a 3.55 ERA and a 3.30 FIP in 63.1 innings pitched, along with a 30.3 K% and a 7 BB%.
It’s clear that the Blue Jays were being aggressive with the left-handed pitcher, and that trend continued in 2022 when they promoted him to Triple-A Buffalo. With the Bisons in 2022, Eisert posted a 3.41 ERA and a 3.57 FIP in 60.2 innings pitched, along with a 31 K% and a 6 BB%. For pitchers with 40+ innings pitched, Eisert’s 25 K-BB% of 25% ranked below only Ricky Tiedemann and Dahian Santos.
Heading into the 2023 season, Eisert ranked as my 44th-best Blue Jays’ prospect, here is my scouting report on him:
“Compact body, broad shoulders, and muscular legs, Eisert’s 3/4 release point deceives batters, especially those on the left side. Low velocity, but it plays up with release point and extension, and works best at the top of the zone. His sweeping slider runs far off the plate for left-handed batters, and his changeup is a weapon against righties with its late vertical break. Where Eisert excels is locating his pitches, which can take him to the next level. In the rare times he misses his spots, he is hit hard.”
Eisert had one of the funniest stat lines in 2023, posting a 4.20 FIP in 69 innings pitched with the Bisons. The jokes write themselves. On top of that, his ERA elevated to 4.17, along with a drop in his K% to 26.2%, while his BB% increased to 8.6%. It wasn’t a terrible year by any stretch, but it wasn’t as good as the season prior.
On the surface level, his numbers in Triple-A in 2024 may have you asking “how the heck was he called up?”, as Eisert has a 6.35 ERA and a 4.28 FIP in 22.2 innings pitched, along with a 33 K% and a 13.2 BB%.
Well, dear viewer, Eisert gave up seven earned runs in his first two thirds of an inning pitched, giving him a 94.50 ERA after his first outing of the season. In 22 innings pitched since, he’s only given up nine earned runs for a 3.68 ERA and a 3.08 FIP, along with a 35.1 K% and a 13.4 BB%. So removing one outing, which is totally fair in this scenario, shows us that Eisert has been great with Buffalo this season.
So what allows Eisert to have success? Well, the 26-year-old has a funky delivery and is tough on left-handed batters because of it. The fastball sits in the low 90s, but the deception he has on it makes it play up. He also has a wipeout slider and a late-tumbling changeup he can throw to right-handed batters.
We’ll see if Eisert is called back up, but he’s certainly a player worth monitoring, especially now that he’s on the 40-man roster.
