Diekman (1-0) picked up the win Monday against Atlanta, allowing one run on zero hits and one walk in an inning of relief. He struck out one.

EDGE Analysis

After shutting down Atlanta in the seventh inning, the southpaw came back out for the eighth and walked Michael Harris before exiting, only to see Drew Smith eventually issue a bases-loaded walk that stuck Diekman with a run on his ledger. He still got credit for the win after the Mets took the lead for good in the top of the eighth. Diekman's 8.10 ERA on the season is a bit deceptive, as he has a 1.20 WHIP and 4:3 K:BB through 3.1 innings, and he's picked up two holds in his four appearances in addition to Monday's win.

Diekman appears locked into a spot in the Mets' Opening Day bullpen, Will Sammon of The Athletic reports.

EDGE Analysis

The 37-year-old southpaw has pitched for four different teams over the last two seasons with mixed results, posting a 4.17 ERA and 1.48 WHIP over 114.1 innings despite 143 strikeouts, as he also issued 80 walks. Diekman's numbers were much better at the end of last year with the Rays however, and the Mets are counting on that improvement to carry forward into 2024 after signing him to a one-year, $4 million contract in February. His spring results have been relatively encouraging, as he has a 7:3 K:BB through six innings while allowing two runs. Diekman figures to be the second lefty in the bullpen behind Brooks Raley, a role that should get him back to double-digit holds after he managed only eight in 2023.

Diekman signed a one-year, $4 million contract with the Mets on Friday, Anthony DiComo of MLB.com reports.

EDGE Analysis

The deal also includes a vesting option for 2025. Diekman held a 2.18 ERA and 53:25 K:BB over 45.1 innings for the Rays last season after being released by the White Sox. The left-handed reliever has a long history of control problems and swing-and-miss ability and the Mets will be hoping for more of the latter than the former in 2024.

Diekman was activated from the paternity list by the Rays on Thursday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Diekman missed the first three games of the series against the Blue Jays but is back for the finale. Ben Heller was optioned in a corresponding move.

Diekman was placed on the paternity list Monday.

EDGE Analysis

Diekman will be away from the team for up to three days while with his expanding family. Right-hander Zack Burdi was called up from Triple-A Durham to replace him on the major-league roster in the meantime.

Diekman finalized a one-year contract with the Rays on Wednesday.

EDGE Analysis

Tampa Bay designated right-hander Chase Anderson for assignment to clear a spot on the 40-man roster and 26-man active roster for Diekman. The 36-year-old will provide the Rays with another left-handed relief option in the wake of Garrett Cleavinger's (knee) season-ending injury. Diekman had posted a 7.94 ERA and 2.12 WHIP in 11.1 innings with the White Sox before being released over the weekend.

Diekman and the Rays are finalizing a major-league contract Tuesday, Jeff Passan of ESPN.com reports.

EDGE Analysis

After being released by the White Sox on Saturday, Diekman could quickly find a new home with Tampa Bay. The left-hander struggled to an abysmal 7.94 ERA and 2.12 WHIP with 11 strikeouts over 11.1 innings in 13 appearances with Chicago this season. Diekman has not officially signed with the Rays quite yet, but if he does finalize a deal, he'd help replace Garrett Cleavinger (knee) in the bullpen.

Diekman was released by the White Sox on Saturday, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

Diekman owns a career 3.96 ERA over parts of 12 big-league seasons, but it's not clear that there's much left in his 36-year-old left arm. After posted a 4.99 ERA last season, he owns a 7.94 ERA in 11.1 frames this year, walking more batters (13) than he struck out (11).

Diekman was designated for assignment by the White Sox on Tuesday.

EDGE Analysis

The White Sox needed to free up multiple 40-man roster spots as part of a slew of moves Tuesday. Diekman's tenure in Chicago went horribly, as he posted a 7.04 ERA over 39 appearances. The 36-year-old will look to catch on elsewhere after clearing waivers and might have to accept a minor-league contract at this point.

Diekman threw a scoreless seventh inning with two strikeouts to earn a hold Wednesday against the Royals.

EDGE Analysis

The White Sox have wasted no time utilizing their only acquisition at the trade deadline, as Diekman has pitched both Tuesday and Wednesday. He worked the sixth and seventh innings respectively, tallying a hold on each occasion. Though Diekman won't factor into the saves picture without a number of injuries in the bullpen, it appears that he will have a high-leverage role with his new club.
