Romano underwent arthroscopic surgery on his right elbow Tuesday to repair an impingement and will be shut down from throwing for at least six weeks, Keegan Matheson of MLB.com reports.

The 31-year-old has been unavailable due to elbow issues since late May, and it's now unclear whether he'll be able to pitch again this year. Romano missed the first couple weeks of the season with elbow problems and never looked himself in the six weeks he was available with a 6.59 ERA in 15 appearances. Chad Green has stepped up as Toronto's closer with Yimi Garcia (elbow) also on the injured list.

The Orioles optioned Vespi to Triple-A Norfolk on Wednesday.

Vespi allowed just one run in his first 10 innings of big-league action before yielding three runs to the Rangers on Sunday. With Dean Kremer (triceps) returning from the IL, Vespi will be sent back to Triple-A. The 28-year-old owns a 2.84 ERA across 25.1 innings with Norfolk this season.

The Rays recalled Sterner from Triple-A Durham on Wednesday, Ryan Bass of Bally Sports Sun reports.

He will take the roster spot vacated by Aaron Civale, who has been traded to the Brewers. Sterner has made two appearances out of the Rays' bullpen this season, allowing two runs (one earned) with a 4:1 K:BB over four innings. He'll be used in low-leverage spots.

Miller allowed two earned runs on two hits and a walk over one inning in a 7-5 win over the Angels on Tuesday. He struck out two.

Miller had last seen action Friday, so manager Mark Kotsay opted to give his closer some work in what started as a low-leverage scenario. The fireballing right-hander inherited a 7-3 advantage going into the ninth inning and proceeded to retire two of the first three hitters he faced, but he subsequently allowed an RBI double and single to Nolan Schanuel and Luis Rengifo, respectively, to tighten matters up. Miller bore down and retired Taylor Ward on four pitches to put an end to the threat and the game, but not before allowing multiple earned runs for the first time since May 23. Despite the stumble, Miller has contributed a win and 14 saves to fantasy managers this season, accomplishing those marks with the help of a stellar 15.8 K/9.

Kopech (2-7) allowed one hit and one earned run across 0.2 innings and took the loss Tuesday against the Guardians.

Kopech entered the game in the ninth inning with the score tied at 6-6. He allowed a leadoff single and threw a wild pitch to put the runner on third base before allowing a sacrifice fly to bring in the game-winning run for Cleveland. Kopech has each of the White Sox's last two saves and should remain the team's primary closer despite a 4.50 ERA and 1.39 WHIP in 36 innings this season.

Sandlin (back) has been sent to Triple-A Columbus to begin a rehab assignment.

Sandlin went on the 15-day injured list two weeks ago with lower-back inflammation but is ready to test things out in a game setting. Since he hasn't missed much time, Sandlin shouldn't require too many rehab outings before being activated.

Duran struck out one in a perfect ninth inning Tuesday to record his 13th save of the season in a 5-3 win over the Tigers.

After missing the first month of the season with an oblique strain, Duran has had a little trouble finding his usual form, but he may be coming around. The right-hander has been scored upon only once in his last 11 appearances, posting a 1.64 ERA, 0.55 WHIP and 9:2 K:BB through 11 innings over that stretch while collecting three wins, three saves and a hold.

Hendriks (elbow) will throw a bullpen session Wednesday at loanDepot park in Miami, Peter Abraham of The Boston Globe reports.

Wednesday's bullpen will be the first of three scheduled sessions for Hendriks, who is recovering from Tommy John surgery. He will throw again Friday and Sunday while the Red Sox are in New York for a series against the Yankees. Hendriks said Wednesday's session is about throwing pitches, while the weekend work is more about mechanics. He's essentially recovered from the surgery and is now building up arm strength.

Mata (shoulder) allowed one unearned run on two hits and two walks while striking out two over 2.1 innings for Triple-A Worcester on Tuesday.

The Red Sox were hoping for Mata to last three innings, but he needed 51 pitches to get seven outs and was removed. The 25-year-old right-hander has been on the injured list all season because of a hamstring injury and then a shoulder issue. In seven rehab appearances, Mata has a 4.24 ERA with 12 strikeouts, five walks and three hit batters over 17.0 innings.

Green picked up the save Tuesday against Houston, allowing one hit and no walks with two strikeouts across a scoreless inning.

Green has stepped into a temporary ninth-inning role with Jordan Romano (elbow) and Yimi Garcia (elbow) shelved. Though the pair have been sidelined for multiple weeks, Tuesday's contest was the first save opportunity offered since and Green stepped up and converted. Green has been exceptional for the Blue Jays this season, posting a 1.37 ERA with a 17:4 K:BB across 19.2 innings.
