The Red Sox will recall Murphy from Triple-A Worcester prior to Friday's game in Arizona, Chris Cotillo of MassLive.com reports.

He'll take the roster spot vacated by Jordan Hicks (shoulder), who is heading to the 15-day injured list. Murphy has made 14 appearances out of the Boston bullpen this season, collecting a 3.05 ERA and 19:10 K:BB over 20.2 frames. He'll be used in long relief.

The Red Sox will place Hicks on the 15-day injured list prior to Friday's game in Arizona with a right shoulder injury, Chris Cotillo of MassLive.com reports.

Hicks gave up four runs while recording just one out in an appearance Wednesday versus the Guardians and holds an 8.20 ERA and 15:12 K:BB over 18.2 innings during his time with the Red Sox. He would be eligible for activation Sept. 19, but between the nature of the injury and Hicks' struggles, his season could be over.

Williams (3-6) took the loss against Houston on Wednesday, allowing four runs on one hit and three walks while striking out two batters over two-thirds of an inning.

The game was tied 4-4 when Williams took the mound in the eighth inning. He immediately found himself in trouble, giving up a double and a walk to the first two batters he faced. Williams fanned two of the next three hitters to nearly wiggle out of the mess, but he then walked in a run before giving way to Camilo Doval, who allowed all three of his inherited runners to score. Williams has been prone to blowups this season -- he's given up multiple runs in 10 outings, and in half of those instances he's surrendered at least three runs. Despite an impressive 78:23 K:BB over 53 frames, his ERA sits at an ugly 5.60 on the season.

Burke earned a hold against Kansas City on Wednesday by pitching a clean sixth inning.

Burke entered with the Angels up by a run in the sixth inning. He made quick work of the Royals, retiring the side in order on 10 pitches. Burke is having a solid season, posting a 3.09 ERA, 1.25 WHIP and 46:18 K:BB over 63 appearances spanning 55.1 frames. He's already reached a career-best mark with 14 holds.

The Cardinals are hopeful O'Brien (shoulder) will be available to pitch Friday against the Giants, the St. Louis Post-Dispatch reports.

O'Brien hasn't pitched in a week due to lingering right shoulder soreness, but he played catch earlier this week and could be cleared for game action after the team's off day Thursday. The 30-year-old collected two saves and three holds in August and boasts a 1.69 ERA and 35:17 K:BB over 37.1 innings this season.

Blewett (elbow) allowed two runs on three hits over an inning in his first rehab appearance with Triple-A Norfolk on Wednesday.

It was Blewett's first appearance in a game since he went down with right elbow discomfort just before the All-Star break. He'll need a few more rehab outings but could be activated from the 60-day injured list when first eligible Sept. 15.

Vesia (oblique) struck out one in a perfect inning in his first rehab appearance with Triple-A Oklahoma City on Wednesday.

Vesia has missed the last two weeks of action with a right oblique strain but didn't seem to show any rust in his first rehab outing. The reliever could make one more rehab appearance before being activated from the 15-day injured list on Sunday, the first day he's eligible.

Walker earned a save against the Rockies on Wednesday, allowing one hit while striking out one batter over a scoreless two-thirds of an inning.

It didn't seem like Walker would be needed with the Giants beginning the bottom of the ninth inning with a 10-5 lead, but he was called upon to put out a fire after Colorado loaded the bases with one out. Walker gave up a sacrifice fly followed by a two-run double, but none of those runs were charged to his ledger. Since he entered with the tying run on deck, Walker was able to get credit for a save by finishing out the contest despite allowing his team's lead to shrink. He's now completed 10 straight scoreless appearances, posting a 0.86 WHIP and 12:0 K:BB over 9.1 frames during that span.

Romero earned a save against the Athletics on Wednesday, allowing two hits while striking out one batter over 1.2 scoreless innings.

Romero entered with one out in the top of the eighth frame when St. Louis led by two runs. He allowed a single to the first batter he faced before retiring the next two hitters. Romero then returned for the ninth and gave up a leadoff single, but that was quickly wiped out on a double play. Romero subsequently wrapped things up to finish with his seventh save of the season, four of which have been longer than an inning in length. With Riley O'Brien (shoulder) currently on the shelf, Romero is the clear top option for save chances for the Cardinals.

Detmers earned the save in Wednesday's 4-3 win over the Royals, striking out two in a perfect ninth inning.

With Kenley Jansen pitching three out of the last four days, Detmers was called upon to protect a one-run lead and shut down the Royals on 13 pitches. The right-hander hasn't allowed a run in 12 of his last 13 appearances and has given manager Ron Washington reason to utilize him in high-leverage scenarios like Wednesday's when necessary.
