Baltimore Orioles Top Prospects For 2027 Fantasy Baseball

I’m Conor McGovern, and I write a semi-regular column covering the Double-A Eastern League for The Dynasty Dugout from my spot in Prince George’s County, Maryland. In addition to my day job as an agricultural economist and social scientist, I also run the Dynasty Index statistical tracking site and write occasional articles with deep analyses of baseball statistics on my own blog, Green Spreadsheets of the Mind. I was really happy when Chris asked me to do the Orioles’ top prospects list for 2027, since it forced me to make a list for the first time.

To get the full report, you need to be a paid subscriber. Why? These reports take a ton of time, and I feel like they are as good as any in the industry. It is filled with advanced data, scouting thoughts, live look reports, long-term outlooks, and more. Each team report is around 8,000 words to help you better understand the prospects. I include peak projections, future fantasy grades, variance factors, and dynasty buys and sells. To see a preview, check out the article below.

Baltimore Orioles Top Prospects for 2027

1. Anthony Eyanson, RHP, 22, 6’2”/208, AA

The Orioles’ system was already one of the strongest in baseball prior to the 2026 trade deadline, and it only got better from there. The prize of the Adley Rutschman haul is Anthony Eyanson, a 22 year-old right-hander who the Red Sox took in the third round of last year’s MLB draft and who rocketed to top-25 prospect status this season. Eyanson made five starts in High-A this year and struck out nearly half of the batters he faced, with a walk rate under 5 percent. He then made 11 appearances with Double-A Portland before being moved to the deadline and resuming his Eastern League season with six appearances at Chesapeake. In his seventeen Double-A appearances, he posted a 1.82 ERA, 1.08 WHIP, 2.80 FIP, and a top-decile strikeout rate, K-BB%, and CSW%. Eyanson is an elite pitching prospect, in the top-three among undebuted pitchers alongside Seth Hernandez and Ryan Sloan and closer to the Majors than either of them.

Eyanson gets there with a unique three-pitch arsenal from a high slot that features almost no horizontal movement. His four-seamer sits around 94 but plays up thanks to near-seven-foot extension; he got up over 100 with it in the Spring Breakout game, so there’s extra juice to squeeze if he needs it. It gets about 17 inches of vertical break, a nice shape that works well off his other pitches. His slider gets used about as frequently as the fastball, and it’s a true gyro slider at 85 with practically zero vertical or horizontal break. He also throws a curveball that sits in the high 70s and drops over 15 inches, working as a true mirror to the fastball. There’s no other pitcher in affiliated baseball – at least none of which I’m aware – that features an arsenal like Eyanson’s. Chase Burns and Dylan Cease have a little similarity, but it’s a little less strict and both have one or more pitches with significant horizontal break. Nevertheless, that ain’t bad company to keep.

The vertical railroad Eyanson’s pitches sit on makes recognition very difficult for batters, and the gulf in break and velocity is so vast that finding the ball with the bat is a tough ask for even the most accomplished swingers. Even when batters do make contact, it’s a lot of grounders – Eyanson’s GB% was in the top decile in Double-A. I wouldn’t be shocked to see the Orioles add a fourth pitch, maybe a changeup or a cutter that he can pull out on occasion to give him some movement on the horizontal plane. Speaking to the difficulty in pitch recognition is that Eyanson arguably gets better the second time through the order, with a lower wOBA against compared to the first time he sees a batter (.242 to .253).

Eyanson will likely make his debut in Baltimore some time in 2027, and he could become one of the best pitchers in baseball for a long time.
