Yacabonis will serve as the opener Sunday against the Blue Jays, Roch Kubatko of MASN Sports reports.

Yacabonis last worked as an opener July 25 and allowed one run on one hit and two walks over two innings. Tom Eshelman will follow as the primary pitcher.

Diaz was called up from Double-A New Hampshire Saturday.

Nick Kingham (oblique) was placed on the 10-day injured list in a corresponding move. Diaz owns an 8-7 record, 4.15 ERA and 1.30 WHIP across 19 starts with New Hampshire. The 22-year-old right-hander will look to provide bullpen depth upon making his major-league debut.

Giles (elbow) should be available out of the bullpen Sunday against the Orioles, Shi Davidi of Sportsnet.ca reports.

He threw 15 pitches off a mound Saturday, which Davidi thinks will be the final step in his rehab from elbow inflammation. This was the first time he threw off a mound since getting a cortisone shot earlier in the week.

Castro is unavailable to pitch Saturday due to an illness, Rich Dubroff of BaltimoreBaseball.com reports.

Castro has been sick and unavailable out of the bullpen for the entire series thus far. The 24-year-old right-hander was 1-0 with a 3.38 ERA and 14 strikeouts across 10.2 innings in July.

Green will start Game 2 of Saturday's doubleheader against the Red Sox, Meredith Marakovits of YES Network reports.

He has not logged more than 2.1 innings in an outing this season, so he obviously won't go deep enough to get a win. Chance Adams seems like a likely primary pitcher to relieve Green.

Alvarado (oblique) will begin a rehab assignment with High-A Charlotte on Sunday, Neil Solondz of the Rays Radio Network reports.

Alvarado has been out since early July with a strained oblique. An exact return timeline has yet to be established, but he could return as soon as next Friday in Seattle if he looks good during his rehab outings. He needs to work on his command as much as working on getting healthy, as he struggled to a 12.54 ERA and a 19.6 percent walk rate over his final 12 outings prior to the injury.

Richards will join Triple-A Durham to start Sunday, Marc Topkin of the Tampa Bay Times reports.

Richards was converted to a bullpen role during his last week in Miami, but the Rays seemingly still view him as a starter. He should spend a fair amount of time in Tampa over the last two months once he's stretched out again.

Covey was recalled from Triple-A Charlotte on Saturday.

Covey spent less than a week in the minors, returning Saturday with Carson Fulmer (hamstring) landing on the injured list. Covey has had a rough time in the big leagues this season, recording a 6.99 ERA in 47.2 innings, though he owns an excellent 1.85 ERA in 24.1 frames for Charlotte.

Fulmer landed on the 10-day injured list Saturday with a strained right hamstring.

Fulmer had only just gotten recalled Tuesday, throwing three scoreless innings in his latest stint in the big leagues and lowering his season ERA to 5.30. Dylan Covey was recalled in a corresponding move.

Blach was claimed by the Orioles and optioned to Triple-A Norfolk on Saturday.

Blach spent parts of four seasons in the big leagues with the Giants but never really established himself, recording a 4.56 ERA and a poor 12.4 percent strikeout rate. He owns a 5.93 ERA in 91 innings with Triple-A Sacramento this season.
