The Red Sox optioned Weissert to Triple-A Worcester on Monday, Julian McWilliams of The Boston Globe reports.

EDGE Analysis

Weissert has struggled over the last month, giving up 17 runs across 12.2 innings covering his last 11 relief appearances. He'll be moved off the active roster to clear a spot for Trey Wingenter.

Weissert (2-2) allowed three runs (one earned) on three hits and two walks over 1.1 innings, picking up a blown save and the loss in extra innings to the Dodgers on Saturday.

EDGE Analysis

Weissert entered in the 10th inning and gave up a pair of run-scoring hits that wiped out Boston's two-run lead. He was allowed to come back for the 11th and permitted a walk-off, bases-loaded single. It was the second consecutive game that the Red Sox's bullpen blew a late-game lead, as the team may be feeling the absences of Justin Slaten (elbow) and Chris Martin (elbow). Weissert entered the contest having allowed 12 runs (10 earned) on 12 hits and four walks over his previous 7.2 innings.

Weissert earned a save against the Marlins on Thursday by allowing an unearned run on two hits over one inning.

EDGE Analysis

Primary closer Kenley Jansen was deployed in a tie game in the ninth inning, so Boston turned to Weissert after taking a two-run lead in the top of the 12th frame. The right-hander gave up a leadoff single followed by a sacrifice fly to allow the automatic runner to cross the plate, but he was able to close out the contest despite giving up another hit with two outs. The save was the first of his career for Weissert, who has been used mainly in lower-leverage situations this season. He has just two holds over 37 appearances while posting a 3.41 ERA and 39:9 :BB across 37 innings.

Weissert retired the lone batter faced in Tuesday's 4-2 loss to Atlanta.

EDGE Analysis

Weissert stranded a runner when he got Ronald Acuna on a force out to end the seventh inning. It was the eighth consecutive scoreless outing for Weissert, who has excelled as part a bullpen that ranks eighth in the majors with a 3.38 ERA. The right-hander sports a 1.17 ERA and 0.91 WHIP with 16 strikeouts and three walks over 15.1 innings.

Weissert (0-1) was charged with the loss against the Angels on Saturday. He allowed two unearned runs on one hit and one walk while striking out one over 1.1 innings.

EDGE Analysis

Weissert maintained a streak of five appearances without allowing an earned run but was victimized by shaky infield defense behind him. The right-hander has allowed three hits and two walks while striking out five over 4.2 innings.

Weissert will make the 2024 Opening Day roster, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Weissert was in danger of being left off the roster as long as Brennan Bernardino was projected to begin the year in the bullpen, but skipper Alex Cora stated Tuesday that Weissert had made the team over Bernardino, who was optioned to Triple-A Worcester. Weissert appeared in 17 games a season ago for the Yankees, posting a 4.05 ERA and 1.45 WHIP with 22 punchouts across 20 innings.

Weissert struck out one over a hitless and scoreless relief inning in Wednesday's spring game against the Yankees.

EDGE Analysis

Weissert, who was acquired from the Yankees in the Alex Verdugo trade, has allowed one run on three hits and two walks while striking out seven over 5.2 Grapefruit League innings. There are few moving parts as the Red Sox evaluate bullpen arms, and Weissert appears to be on the bubble at this stage. He was added to the bullpen in a roster projection compiled by Mac Cerullo of the Boston Herald, who noted Zack Kelly, Chris Murphy, Joe Jacques, Joely Rodriguez and Lucas Luetge as possibilities.

The Yankees traded Weissert to the Red Sox on Tuesday alongside Richard Fitts and Nicholas Judice in exchange for Alex Verdugo, Jeff Passan of ESPN.com reports.

EDGE Analysis

Weissert logged a 4.05 ERA and 1.45 WHIP through 20 innings with the Yankees last season, and he'll now switch sides in one of the most intense rivalries in baseball. As part of one of one of the best bullpens in the majors in 2023, Weissert managed just two holds in 17 appearances. Now with Boston, he may receive more late-game opportunities with a bullpen that ranked closer to the bottom of the AL in ERA last year (4.32).

Weissert was recalled from Triple-A Scranton/Wilkes-Barre on Sunday.

EDGE Analysis

The 28-year-old was sent to Triple-A on Aug. 20 but will rejoin the major-league club with Ian Hamilton (groin) placed on the injured list. Weissert has made seven appearances for the Yankees this season and has allowed four earned runs with a 9:5 K:BB over 8.2 innings.

Weissert was optioned to Triple-A Scranton/Wilkes-Barre on Sunday.

EDGE Analysis

Weissert allowed a run on two hits and no walks while striking out two in two relief innings against the Red Sox on Friday after being called up by the Yankees that day. However, he'll head back to the minors with Carlos Rodon (hamstring) slated to return from the injured list Tuesday.
