2023 Fantasy Outlook
It was a nice moment when Eflin, who'd endured more of the Phillies' playoff drought than most, recorded his first career save in the game which clinched the the team's first playoff berth since 2011, but the fact that he was pitching in relief in the first place is unfortunately what fantasy managers should be primarily concerned with. Knee issues limited Eflin to 18 starts in 2021, and they didn't go away in 2022. He finished with 13 starts and seven relief appearances. When healthy, he was the same unexciting but capable pitcher he's been for the past several seasons, as his 4.04 ERA and 20.8 K% were both near matches for the 4.12 ERA and 21.4 K% he managed from 2019 through 2021. His 4.8 BB% was excellent, as usual, but while many low-whiff, low-walk pitchers become durable back-end starters, Eflin's injuries mean he lacks that reliability. The Rays are betting on some untapped potential and gambling on his health, as they gave him the richest free agent contract in team history (three years, $40 million). He should open the year in the middle of the rotation. Eflin's sinker and cutter show some intriguing movement qualities and he excelled at limiting hard contact last season (96th percentile average exit velocity), so perhaps the Rays can extract a career year with the aid of a massive home park upgrade.

From Ronald Acuna Jr. to Ryan Jeffers, the RotoWire Roundtable crew shares their updated top-300 rankings.

Ryan Boyer continues his draft-day review series, this time taking a look at how Zach Eflin pulled off such a strong season.

The RotoWire Roundtable is back early this year, featuring an unsurprising consensus top pick followed by plenty of disagreement.

James Anderson put together a super-early top 300 for 2024 redraft fantasy baseball leagues and Ronald Acuna was the undisputed choice atop the rankings.

2014
Eflin was more interesting than ever last offseason, as he'd just seen his K% jump by over 10 points to 28.6, helping him to a career-best 3.97 ERA, a number which could have been considerably better according to the ERA estimators. He was unable to repeat the feat in 2021, producing the unremarkable numbers we've seen from him throughout his career. He did show excellent control, with his 3.6 BB% leading all pitchers who threw at least 100 innings, but his K% fell back to a below-average 22.4%. That added up to a 4.17 ERA, though the ERA estimators were again about half a run more optimistic. Eflin's standout control keeps him somewhat interesting heading into this season, but he now comes with injury concerns, as a patellar tendon issue kept him out for most of the second half and eventually required surgery. His availability for Opening Day is up in the air, though he's trended in the right direction early on in spring training and may not miss much time, if any, to open the season.
