Diaz will be traded from the Mariners to the Mets on Monday once all physicals have been completed, Joel Sherman of the New York Post reports. The Mets will also receive Robinson Cano and cash considerations, while the Mariners will receive Jay Bruce, Anthony Swarzak, Jarred Kelenic, Justin Dunn and Gerson Bautista. The Mets acquire a top-tier closer, as Diaz saved 57 games last season on the back of a 1.96 ERA. That ERA was actually higher than his 1.61 FIP, as he struck out an incredible 44.3 percent of opposing batters while walking just 6.1 percent. It's highly unlikely that Diaz will reach 57 saves again, as that figure tied for the second-highest in MLB history, but he should remain an excellent reliever and should have plenty of save chances if the Mets keep improving their team.
Diaz worked out of a bases-loaded jam and struck out three in a scoreless inning to record the save Saturday against the Rangers. Diaz allowed just one hit, but he also hit a batter and put another one on due to an error. He struck out Jurickson Profar with the bases loaded to get his 57th save, tied for the second-highest single-season total in the modern era. He's also posted a 1.96 ERA and 0.79 ERA with 124 strikeouts across 73.1 innings.
Diaz picked up his 56th save of the season in Monday's win over the Astros. He needed just five pitches to complete a perfect ninth inning. Diaz now has two saves in the last three days after only having one in the previous 10. While he will likely fall short of K-Rod's record of 62 saves, Diaz has established himself as one of the best closers in all of baseball.
Diaz allowed a solo home run and struck out a better to earn the save Saturday against the Angels. Diaz gave up a solo home run to Justin Upton but still managed to record his 55th save of the season. It was his second consecutive outing allowing an earned run, but there shouldn't be much cause for concern as he has allowed only three earned runs across his last 10.1 innings. He continues to pace the league in saves by a wide margin -- Craig Kimbrel is next closest with 41 -- and will undoubtedly keep that crown until season's end.
Diaz (0-4) was tagged with the loss Tuesday, allowing one run on three hits while striking out one in an inning of work against the Padres. Manager Scott Servais turned to Diaz in a non-save situation with the score tied at one entering the ninth inning, but Diaz allowed the game-winning run to come around on a couple of singles and a double. Even with Tuesday's slip-up, the 24-year-old has elite ratios (1.95 ERA, 0.79 WHIP) and has a commanding lead league-wide with 54 saves.
