Green (elbow/head) is in concussion protocol after getting beaned by a catcher's throw to second base Tuesday with Triple-A Buffalo, Arden Zwelling of Sportsnet.ca reports.

Green was making what might have otherwise been his final rehab appearance when Buffalo catcher Tyler Heineman drilled him in the head while trying to cut down a stolen base attempt from Triple-A Worcester shortstop Ryan Fitzgerald. Green is fully recovered from Tommy John surgery, but there is no longer an exact timetable for his Blue Jays debut. He'll likely be sidelined for at least a week before beginning a new minor-league rehab stint.

The Tigers outrighted Logue to Triple-A Toledo on Wednesday.

Logue was moved off the Tigers' 40-man roster earlier this week, but he'll stick around the organization after clearing waivers. The 27-year-old lefty has spent the majority of the season at Toledo, where he's compiled a 6.22 ERA and 1.74 WHIP across 63.2 innings.

The Yankees announced that Hamilton will serve as their opening pitcher for Wednesday's game against the White Sox, Gary Phillips of the New York Daily News reports.

Wednesday is Luis Severino's turn in the rotation, but because the right-hander has struggled in most of his recent outings, manager Aaron Boone will see if Severino fares any better while working behind an opener. Hamilton will be making his second "start" of the season, with his first coming during a July 1 game against the Cardinals in which he worked just one inning. He'll likely be capped at around 1-to-3 innings Wednesday before turning the game over to Severino and the bullpen.

The Mariners designated Muckenhirn for assignment Wednesday.

The southpaw will move off the Mariners' 40-man roster with Seattle needing to clear a spot for right-hander Emerson Hancock, whose contract was selected from Double-A Arkansas ahead of his first MLB start Wednesday versus the Padres. Since being acquired in a trade with the Mets on July 3, Muckenhirn has pitched exclusively at Triple-A Tacoma, where he turned in a 9.35 ERA and 1.95 WHIP over 8.2 innings.

The Mariners optioned Sweet to Triple-A Tacoma on Wednesday.

Sweet will cede his spot on Seattle's 26-man active roster to right-hander Emerson Hancock, who had his contract selected from Double-A Arkansas in advance of his first MLB start Wednesday versus the Padres. After getting called up from Tacoma shortly after the All-Star break, Sweet made just two relief appearances for Seattle, giving up two earned runs over two innings.

Martinez, recalled from Triple-A Las Vegas earlier in the day, allowed two earned runs on four hits and three walks over 4.2 innings during a loss to the Rangers on Tuesday. He recorded five strikeouts and did not factor into the decision.

The young right-hander was afforded an 82-pitch assignment right out of the gate in his first taste of major-league action since May 26. Martinez ate up some valuable innings in the process, getting all but the last out of the night for the Athletics after starter JP Sears exited following four laborious frames. Martinez is slotting into a bullpen role for the time being, but as the length of Tuesday's appearance indicates, he's capable of serving in a bulk-relief capacity or even moving into the rotation if necessary.

Brash secured his 16th hold in the Mariners' win over the Padres on Tuesday, firing a scoreless eighth inning during which he allowed a hit and a walk, threw a wild pitch and recorded a strikeout.

It was an eventful frame for Brash. He displayed some of the control issues he's gotten a better handle on this season, but the hard-throwing right-hander still managed to escape unscathed and post his seventh straight scoreless appearance. Brash has primarily filled a setup role since the trade of Paul Sewald at the deadline to the Diamondbacks, although he has seen one save chance in that span that he successfully converted. Andres Munoz is proving capable of manning the closer role for the time being, but Brash should continue drawing plenty of hold opportunities down the stretch and also log the occasional ninth-inning assignment.

Krehbiel was optioned to Triple-A Norfolk on Wednesday, Steve Melewski of MASNSports.com reports.

He's moved off the 26-man active roster as the Orioles make room for right-hander Jacob Webb, who was claimed off waivers Monday from the Angels. Krehbiel has made two scoreless appearances during his brief time with the Orioles this season.

Walter was recalled from Triple-A Worcester on Wednesday, Christopher Smith of The Springfield Republican reports.

Walter has collected a 3.07 ERA over 14.2 innings covering six appearances for the Red Sox this season. The left-hander will give the club an option to eat some innings out of the bullpen.

Robertson was optioned to Triple-A Worcester on Wednesday, Christopher Smith of The Springfield Republican reports.

Robertson allowed four runs over four frames during his brief time in Boston after coming over from the Dodgers in a trade. He's being replaced by a fresh bullpen arm in right-hander Kyle Barraclough, whose contract was selected from Triple-A in a corresponding move.
