Availability
The Mets have designated Jake Diekman for assignment.
Fantasy Impact
Diekman will be cast off the 40-man roster in favor of Matt Gage, who will be promoted from Triple-A Syracuse. He will hit the waiver wire after posting a 5.63 ERA and a 1.47 WHIP in 43 games this season.
Jake Diekman recorded the final out on Sunday to earn the save against the Mets.
Fantasy Impact
With Edwin Diaz ejected from the game before he threw a pitch, Drew Smith recorded the first two outs of the ninth inning before Diekman closed it out to secure his third save on the season.
Jake Diekman efficiently closed out the Mets' 8-7 victory over the Nationals, securing his second save of the season.
Fantasy Impact
He threw nine pitches, striking out one without allowing any hits or walks in 0.2 innings. This performance could be a slight beacon of hope for fantasy managers, as Diekman's season has been marred by inconsistency, highlighted by a 4.12 ERA and a 1.27 WHIP. His impressive 12.4 K/9 continues to make him a tantalizing option for strikeouts, but his high FIP of 4.94 and shaky control suggest potential volatility. Managers should remain cautious, using him in situations where strikeouts are needed but overall risk can be tolerated.
Jake Diekman notched his first save in the Mets' narrow 6-5 victory over the Phillies.
Fantasy Impact
He pitched a clean inning, allowing no hits and striking out one, though he did issue a walk. This outing was a step in the right direction for Diekman, who has been battling inconsistency, evidenced by a 3.21 ERA and a 1.29 WHIP over 17 appearances this season. His ability to strike out batters remains a strong point, with an 11.6 K/9 rate, but his control issues are highlighted by a less-than-ideal 1.38 strikeout-to-walk ratio. Fantasy managers should view Diekman as a high-risk, high-reward option in leagues counting holds and saves, given his volatile performances but clear capability in high-leverage situations.
The New York Mets have signed reliever Jake Diekman to a one-year deal.
Fantasy Impact
The deal is expected to be for around $5.5 million with a vesting option included, but nothing financial has officially been released. The left-hander produced a healthy 3.34 ERA between the White Sox and Rays in 2023, bouncing back from a 4.99 ERA in 2022. However, Diekman struggles mightily with control as he has walked at least 13% of the batters he has faced in each of his last five seasons, including a 15.6% mark in each of his last two campaigns.
