The Mariners optioned Diaz to Triple-A Tacoma on Tuesday.

Diaz didn't appear in a game after being recalled from the minors last week, and he'll now be sent back down in favor of Casey Lawrence. The 28-year-old Diaz has turned in a 5.87 ERA and 1.49 WHIP across 30.2 innings at Tacoma.

The Mariners selected Lawrence's contract from Triple-A Tacoma on Tuesday.

Lawrence has given up four earned runs in 10 innings with the Mariners this season, and he'll now rejoin the active roster to provide Seattle with a relief option capable of handling multiple innings out of the bullpen. To make room for Lawrence on the 26-man and 40-man rosters, Jhonathan Diaz was optioned to Triple-A, and Austin Shenton was designated for assignment.

The Athletics recalled Maldonado from Triple-A Las Vegas on Tuesday.

Maldonado was sent to Triple-A on Monday to make room for J.T. Ginn's return from the injured list. However, now that Ginn is back on the IL with a quad injury, Maldonado will return to the majors to provide additional bullpen depth while the team looks for a new fifth starter.

The Pirates selected Mattson from Triple-A Indianapolis on Tuesday.

The right-hander will take the roster spot of Colin Holderman, who was placed on the injured list Tuesday due to a thumb injury. Mattson gave up three earned runs in 5.1 frames with Pittsburgh last year and has a 2.33 ERA, 0.94 WHIP and 24:5 K:BB over 19.1 innings this season with Indianapolis.

The Pirates placed Holderman on the 15-day injured list Tuesday due to thumb inflammation, Danny Demilio of PittsburghBaseballNow.com reports.

It's unclear when exactly he suffered the injury, but Holderman had been torched for five runs over his last two appearances. Isaac Mattson will absorb Holderman's spot on the roster and in the bullpen.

The Red Sox optioned Burdi to Triple-A Worcester on Tuesday.

The 32-year-old right-hander appeared in two games for the Red Sox after being selected from Triple-A last Friday. He didn't allow an earned run on four hits across 2.1 innings.

Reds manager Terry Francona said Tuesday that Gibaut (shoulder) is on track to be activated from the 15-day injured list Wednesday, Charlie Goldsmith of the Dayton Daily News reports.

Gibaut has been shelved since late April with a right shoulder impingement but has made four scoreless rehab appearances without any setbacks. He will return to a middle-relief role.

The Cubs recalled Roberts from Triple-A Iowa on Tuesday.

Roberts is back in the majors after the Cubs placed Porter Hodge (oblique) on the 15-day injured list. Roberts has appeared in nine games for Chicago this season, posting a 5.40 ERA and 6:2 KBB across 8.1 innings of work out of the bullpen.

The Cubs placed Hodge (oblique) on the 15-day injured list Tuesday.

Hodge has been diagnosed with a left oblique strain and will miss at least the next couple weeks. In a corresponding move, the Cubs recalled Ethan Roberts from Triple-A Iowa. With Hodge sidelined, Daniel Palencia got the save chance Monday against the Marlins but blew it, surrendering a pair of earned runs on two hits and one walk across two-thirds of an inning. Ryan Pressly should also vie for save opportunities.

The Orioles optioned Strowd to Triple-A Norfolk on Tuesday.

He's exiting the roster to make room for Chayce McDermott, who has been recalled to serve as the team's primary pitcher in Tuesday's game against the Brewers. Strowd made one appearance during his brief time in the majors, allowing one run over an inning of work.
