Hartlieb was claimed off waivers by the Red Sox on Saturday, Tim Healey of Newsday reports.

Hartlieb was designated for assignment by the Mets on Thursday, but he'll join Boston's 40-man roster. The right-hander had been pitching at the Triple-A level before he was DFA'd, and the Red Sox will have to make an additional roster move if they intend to bring him up to the majors.

Underwood exited Saturday's loss to the Cubs with right shoulder discomfort, Alex Stumpf of DKPittsburghSports.com reports.

Underwood allowed a solo home run in the fifth inning and returned to the mound in the sixth, but he was removed from the game after issuing a walk. He'll presumably be evaluated in the coming days to determine the extent of his shoulder injury.

Howard (undisclosed) is back with the team Saturday and should be activated to start sometime during the Rangers' current road trip, which runs through Sept. 12, Kennedi Landry of MLB.com reports.

Howard hit the COVID-19 injured list in late August. He tossed two innings in a rehab outing Thursday, allowing one run on three hits while striking out three batters. It remains unclear exactly when he's expected to return.

Weathers made his most recent appearance out of the bullpen, striking out one over a scoreless inning in Wednesday's 8-3 loss to the Diamondbacks.

Weathers was dropped from the rotation in advance of Jake Arrieta's return from the 10-day injured list Friday to take over the No. 5 starter role. After a promising start to the season, Weathers faltered badly in his final six turns through the rotation, giving up 31 total earned runs in 20.2 innings.

Mills was optioned to Triple-A Tacoma on Saturday, Shannon Drayer of 710 ESPN Seattle reports.

Mills' latest stint in the majors lasted one week. He made just a single appearance, allowing a run on two hits in one inning of work, though that actually lowered his ERA and WHIP to 9.95 and 2.05, respectively.

Milner was optioned to Triple-A Nashville on Saturday.

Milner tried to stop the bleeding Friday after the first four pitchers to take the ball for Milwaukee combined to give up 13 runs, but Milner just made things worse, surrendering two runs of his own in one-third of an inning. The lefty could return to the Brewers' bullpen later in the season, though he could just as easily be DFA'd.

Misiewicz (forearm) was activated off the injured list Saturday.

Misiewicz won't wind up missing more than the minimum 10 days while battling a strained left forearm. He's been a useful part of the Mariners' bullpen lately, allowing an earned run in just two of his last 15 appearances.

Topa was placed on the 60-day injured list Saturday with a right elbow injury.

Manager Craig Counsell called the injury that forced Topa from Friday's game "significant," per Adam McCalvy of MLB.com, and noted that it's Topa's flexor tendon, which was also a problem in spring training. The Brewers are trying to determine the extent of the UCL damage. Topa has shown tremendous resilience, battling back from two Tommy John surgeries and time in independent ball, but a third TJS recovery would be a daunting hill to climb.

Moore will be available out of the bullpen Saturday, with the Phillies expected to go with bullpen days in what had been his spot in the rotation, Scott Lauber of The Philadelphia Inquirer reports.

Moore has been ineffective for most of the season, struggling to a 6.49 ERA and 1.63 WHIP across 13 starts and eight relief appearances. The expanded September rosters mean the Phillies won't need to use him to eat innings, though he could still be used in a multi-inning relief role during those bullpen games.

Vasquez was tagged with a blown save against San Francisco on Friday, pitching two-thirds of an inning and allowing an unearned run on one hit while striking out one.

The left-hander was inserted in a difficult spot in his debut with Los Angeles, as he was asked to protect a one-run 11th-inning lead in the battle for first place in the NL West. Vasquez gave up a single that allowed the inherited runner at second base to score but recovered to retire the next two batters -- including notching a clutch whiff of Mike Yastrzemski with a runner on third base and one out -- before he was removed from the contest. Vasquez doesn't figure to see many situations as stressful as Friday's since he's likely to be used mostly in a low-leverage role while up in the majors.
