Top Of The Line
Andrew Chafin is the best left-handed relief option on the market. The veteran reliever turned in a dominant season with a 2.83 ERA, 3.06 FIP, and 1.17 WHIP. Chafin struck out 27.6% of batters faced with a 7.8% walk rate. He also had a 51.3% ground ball rate and allowed just five home runs in 57.1 innings of work. The underlying numbers liked him too, as he had a 3.27 xFIP and 2.97 SIERA.
The next best option is arguably Taylor Rogers. Rogers is coming off a season in which he could have been a lot better. Despite a 4.76 ERA, Rogers owned a 3.22 FIP, 3.26 xFIP, 2.60 SIERA, and 86 DRA-. Rogers also struck out a whopping 30.7% of batters faced with a walk rate of just 6.6%. It’s not as if he gave up a ton of home runs either, with a 0.98 HR/9. Rogers was simply unlucky in 2022 and a prime rebound candidate for 2023. He also has a decent history of being a dominant high-leverage reliever.
The third reliever I consider more of a higher-end option is Matt Moore. Moore pitched to a 1.95 ERA, 2.98 FIP, and 1.18 WHIP in the lefty’s first year solely out of the bullpen. Moore struck out 27.3% of the batters he faced, which was a career-high.
His 0.36 HR/9 was also a career-best. But luck did play a hand in Moore’s success. He had a 3.87 xFIP and 3.69 SIERA and danced around a 12.5% walk rate. Moore had a .257 batting average on balls in play and a 4.2% HR/FB ratio. But he did limit hard contact to an above-average rate and is still one of the better LHP options available. If he cuts down his walks to below 10%, he’ll be effective in 2023.
