The Dodgers optioned Diaz to Triple-A Oklahoma City on Wednesday.

Diaz's first stint with the Dodgers lasted only one day, and he did not make an appearance. The reliever's removal from the active roster frees up a spot for Tyler Glasnow (shoulder), who was reinstated from the 60-day injured list to start Wednesday's game in Milwaukee.

The Twins selected Misiewicz's contract from Triple-A St. Paul on Wednesday.

The Twins are swapping left-handed relievers, adding Misiewicz to the roster and designating Joey Wentz for assignment. Misiewicz held a 4.02 ERA and 29:10 K:BB over 31.1 innings this season with St. Paul. The 30-year-old has a career 4.67 ERA and 114:38 K:BB over 115.2 frames covering parts of five seasons at the big-league level.

The Twins designated Wentz for assignment Wednesday.

Minnesota claimed Wentz off waivers just under a month ago, and the southpaw was pummeled for 14 runs with a 6:9 K:BB over eight innings for the Twins. Fellow lefty Anthony Misiewicz was called up from Triple-A St. Paul to replace Wentz on the 40-man roster and in the big-league bullpen.

Bivens allowed two earned runs on two hits -- including one home run -- over 1.1 innings in Tuesday's 4-3 win over the Phillies.

Bivens entered the game with two outs and a runner on third base in the sixth, retiring the first batter he faced to end the inning. However, the right-hander gave up a single and a home run in the seventh. Over his last 10 appearances, Bivens owns a 4.02 ERA, 1.09 WHIP and 18:5 K:BB across 15.2 innings.

The Dodgers transferred Kopech (knee) from the 15-day injured list to the 60-day IL on Wednesday.

When Kopech was placed on the IL on July 1 due to right knee inflammation, manager Dave Roberts suggested that the reliever would be in line for a brief stay on the shelf. However, after Kopech received an injection to address the discomfort in his knee, the Dodgers evidently determined that the right-hander would need more time off to recover than anticipated. As a result of Kopech's move to the 60-day IL, he won't be eligible for activation until late August.

Treinen (forearm) will begin a rehab assignment with Triple-A Oklahoma City on Wednesday, Bill Plunkett of The Orange County Register reports.

Treinen has been shelved since mid-April with a right forearm sprain, so he will likely need a handful of rehab outings before rejoining the Dodgers bullpen. The veteran reliever could be back on the active roster for the start of the second half if all goes well during his rehab assignment.

The White Sox sent Booser (shoulder) to Triple-A Charlotte on Tuesday to begin a rehab assignment.

Booser has been cleared to pitch in games after missing the last two-plus weeks with a left shoulder strain. Because his absence has been relatively brief, Booser shouldn't require too many rehab outings before rejoining Chicago's bullpen.

The Yankees designated Hartlieb for assignment Wednesday.

Hartlieb will give up his spot on the 40-man roster and 26-man active roster to right-hander Cam Schlittler, who was called up from Triple-A Scranton/Wilkes-Barre to start Wednesday's game against the Mariners. Hartlieb has made two appearances out of the Yankees bullpen this season, giving up six earned runs in 1.1 innings.

Rodriguez (forearm) yielded one hit and struck out one over a scoreless frame in his first rehab appearance with Triple-A Durham on Tuesday.

It was Rodriguez's first outing in nearly a month, as he is working his way back from a right forearm strain. If all goes well, Rodriguez should have a shot to return before the All-Star break. He's collected a 2.08 ERA and 25:6 K:BB over 30.1 innings out of the Rays' bullpen this season.

Borucki (back) struck out one in a scoreless inning in his first rehab appearance with Single-A Bradenton on Tuesday.

The southpaw landed on the 15-day injured list in late June with a lower-back injury but has been cleared to ramp things back up in game action. Borucki's absence has been brief, so it shouldn't take long before he rejoins the Pirates' active roster.
