Munoz was charged with a blown save in Thursday's 6-5 extra-inning loss to the Yankees, allowing two runs on three hits and one walk with no strikeouts in the ninth inning.

It was the sixth blown save of the season by Munoz, who gave up multiple hits for only the second time out of 36 appearances this year. The hard-throwing right-hander remains Seattle's clear-cut closer, although he's been rather shaky since opening the campaign with a 0.00 ERA through May 29. Over his last 11.1 frames (12 outings), Munoz owns a 4.76 ERA, 1.41 WHIP and 16:6 K:BB.

Campbell was optioned to Triple-A Worcester on Thursday, Christopher Smith of MassLive.com reports.

Campbell had his contract selected Tuesday and made his season debut in the majors one day later with two runs allowed over two innings. The move likely signifies the return of Hunter Dobbins (elbow) from the injured list, but an official corresponding move has yet to be announced.

The Orioles optioned Wolfram to Triple-A Norfolk following Thursday's doubleheader with the Mets, Cordell Woodland of 105.7 The Fan Baltimore reports.

Wolfram threw two scoreless innings in the first game of the doubleheader against the Mets, striking out four while picking up his first career win. He's primarily pitched at Norfolk this season, but he could be back as an extra arm in Baltimore's bullpen if needed later in the summer.

The Orioles recalled Selby from Triple-A Norfolk on Thursday.

Selby has given up two earned runs with a 10:1 K:BB over 5.2 innings at the major-league level this season and has collected a 2.38 ERA and 31:12 K:BB in 22.2 frames with Norfolk. He will provide the Orioles' bullpen with a fresh arm.

Red Sox manager Alex Cora said Thursday that Slaten (shoulder) is no longer throwing and is instead doing plyometric exercises, Christopher Smith of MassLive.com reports.

Out since late May with right shoulder inflammation, Slaten played catch back on June 27, but he's backed off a throwing program since then and is focusing on rebuilding shoulder strength. Once he's throwing again, Slaten will need time to build back up, so he looks to be several weeks away from a potential return.

Yankees manager Aaron Boone said Thursday that he's hopeful Leiter (leg) can resume a throwing program this weekend, Greg Joyce of the New York Post reports.

Leiter landed on the 15-day injured list Tuesday with a left fibular head stress fracture, an injury he actually suffered two weeks prior. It shouldn't take Leiter long to ramp back up from a stamina standpoint, but it's uncertain how his leg will respond to increased activity.

The Athletics optioned Spence to Triple-A Las Vegas on Thursday.

The transaction comes one day after Spence was torched for eight runs over six innings in a loss to Atlanta. Spence was not scheduled for another start before the All-Star break, so the A's have replaced him with some bullpen protection in the form of Osvaldo Bido. It's possible Spence gets another chance in the big-league rotation after the All-Star break, although he won't be eligible to be recalled until July 25.

The Rays optioned Orze to Triple-A Durham on Thursday, Marc Topkin of the Tampa Bay Times reports.

His roster spot will be filled by Bryan Baker, who was acquired via trade earlier Thursday. Orze has been a trusted member of the Rays' bullpen for much of the season, but he's stumbled lately, allowing nine runs (eight earned) over his last 10.2 innings.

Bautista earned the save in the opening game of Thursday's doubleheader with the Mets, delivering a perfect ninth inning to seal a 3-1 win.

Bautista has converted 11 straight save chances while allowing just one earned run in his last 16 innings. Overall, the 6-foot-8 right-hander has posted a 2.41 ERA across 33.2 innings with a 1.04 WHIP and 48 strikeouts while converting 18 of 19 save opportunities.

Williams struck out two in a perfect ninth inning Wednesday to record his 13th save of the season in a 9-6 win over the Mariners.

The Airbender has put a shaky start to his tenure in the Bronx firmly behind him. Williams has converted nine straight save chances since moving back into the closer picture in late May, posting a 3.14 ERA, 0.77 WHIP and 17:2 K:BB over his 14.1 innings, and he's been charged with runs in only one of his last 11 appearances. Given Luke Weaver's current struggles, Williams would seem to have a firm grip on the ninth-inning role for the Yankees.
