The Reds designated Wynns for assignment Tuesday.

Wynns was up as protection at catcher for a few days while Tyler Stephenson was away but is no longer needed with the latter back in the fold. He cleared waivers and accepted an outright assignment to Triple-A Louisville last month, and he seems likely to do so again.

The Reds activated Stephenson (personal) from the family medical emergency list Tuesday.

Stephenson was away from the club for a few days following the birth of his child but is back for the start of its series in New York against the Yankees. Austin Wynns was designated for assignment in a corresponding move.

Ruiz went 3-for-5 with an RBI in Monday's extra-inning loss to the Mets.

It was the backstop's first three-hit performance since March 30, but his third multi-hit effort in his last five starts. Ruiz is showing signs of life at the plate, and over his last 11 games he's batting .289 (11-for-38) with three doubles.

Campusano (thumb) went 0-for-4 with two strikeouts in his first rehab game with Single-A Lake Elsinore on Monday.

Campusano has missed just over a week of action with a thumb injury, so he shouldn't need too many rehab at-bats before being activated. Kyle Higashioka is coming off an eight-homer June, so it's possible Campusano -- who has just a .588 OPS since May 1 -- will play second fiddle at catcher for the Padres upon his activation.

Contreras went 3-for-5 with a solo homer, a double and two runs scored in Monday's loss at Colorado.

The 26-year-old drew the start at designated hitter and reached double-digit homers for the third consecutive season with a solo shot off Austin Gomber. Contreras also collected his team-leading 20th double of the season. Overall, the Milwaukee star is now slashing .296/.355/.451 with 51 RBI and 59 runs scored across 369 plate appearances.

The Reds transferred Stephenson (personal) from the paternity list to the family medical emergency list Monday.

Stephenson had been away for the last three games while on the paternity list. By rule, players can miss 3-to-7 days while on the family medical emergency list, whereas he would have to be activated ahead of Tuesday's game against the Yankees had he remained on the paternity list. Luke Maile and Austin Wynns will handle catching duties for Cincinnati while Stephenson is away.

Davis had his rehab assignment with Double-A Altoona put on hold over the weekend after he experienced recurring concussion symptoms, Alex Stumpf of MLB.com reports.

Initially placed on the 7-day injured list June 15 after experiencing concussion-like symptoms a day earlier in the Pirates' win over the Rockies, Davis was cleared to begin his rehab assignment last Wednesday. However, after appearing in two games with Altoona, Davis suffered an apparent setback and is now without a clear timeline to resume the assignment. With Joey Bart beating Davis back from the 10-day IL on Sunday, the Pirates may not have room for Davis on the big-league roster once his concussion symptoms subside and he's cleared to return from the 7-day IL.

Herrera will become Arizona's backup catcher after the team designated Tucker Barnhart for assignment Sunday, Arizona Sports reports.

Herrera will serve as the backup to Gabriel Moreno (thumb), who is expected to be activated ahead of Tuesday's series opener against the Dodgers. Herrera has not been impactful on offense over parts of three seasons with the Diamondbacks, posting a combined OPS of .497.

Moreno (thumb) is expected to be activated ahead of a three-game series against the Dodgers beginning Tuesday, Arizona Sports reports.

The Diamondbacks designated Tucker Barnhart on Sunday, which indicates Moreno should be ready to go Tuesday after catching in a rehab game at the Arizona Complex League over the weekend. With Barnhart designated, the Diamondbacks will roll with Jose Herrera as the backup catcher.

Diaz went 2-for-4 with a double and a run scored Sunday against the White Sox.

Diaz was activated from the injured list after three weeks and returned to serve as the designated hitter while hitting fifth. He collected a hit in his first plate appearance, showing no signs of rust. Diaz's return will likely push Jacob Stallings into a backup role and could end consistent playing time for Hunter Goodman.
