Kirk (elbow) is not in the lineup for Friday's game against the Yankees.

It's the second straight game out of the lineup for Kirk after being hit by a pitch in the left elbow Tuesday against the Orioles. Brian Serven will receive another look behind the plate in the series opener in the Bronx.

Ruiz (groin) will start at catcher and bat sixth in Friday's game versus the Brewers, Spencer Nusbaum of The Washington Post reports.

Ruiz had to depart the Nationals' last game on Wednesday in Arizona with a groin injury, but he won't wind up missing any starts. The switch-hitting catcher hit four home runs in July, doubling his season total.

Jeffers is not in the lineup for Friday's game versus the White Sox.

He and Christian Vazquez continue to alternate starts at catcher, doing so now for the 14th straight game. Jeffers has just a .561 OPS since the beginning of June.

Dingler is not in the lineup for Friday's contest against the Royals, Evan Woodbery of MLive.com reports.

Since his promotion, Dingler has now started two of six games, with Jake Rogers getting the call behind the plate for the other four. The rookie catcher is 1-for-6 with a 3:1 K:BB in his first seven major-league plate appearances.

The Reds optioned Yang to Triple-A Louisville on Friday.

Yang served as Tyler Stephenson's backup while Luke Maile (back) and Austin Wynns (shoulder) were sidelined, but Maile is back now to reclaim that gig. The 26-year-old Yang struck out in his lone plate appearance.

The Reds activated Maile (back) from the 10-day injured list Friday.

Maile has been out since early July with a herniated disc in his back but is ready to go after playing a couple rehab games with Triple-A Louisville. He'll regain his role as the backup catcher behind starter Tyler Stephenson.

Porter cleared waivers and was outrighted to Triple-A Syracuse by the Mets on Friday.

Porter joined New York on a major-league contract in mid-July and was designated for assignment Tuesday without appearing in a game. The 29-year-old has also spent time in the Giants and Royals organizations this season, and he has a combined .858 OPS in 57 games at the Triple-A level.

Amaya is not in the lineup for Friday's game against the Cardinals.

He was behind the dish for the series opener Thursday but will yield to Christian Bethancourt for Friday's afternoon tilt. Amaya has now made five starts to Bethancourt's three since Tomas Nido (knee) went on the injured list.

The Giants optioned Sabol to Triple-A Sacramento on Thursday.

Sabol had been recalled Tuesday but was sent back down two days later without having appeared in a game. He made room on the active roster for trade acquisition Mark Canha.

Naylor went 1-for-4 with a three-run home run against Baltimore in a 10-3 win Thursday.

Naylor pushed Cleveland's lead to 10-2 in the seventh inning with a three-run blast to right field. The long ball was his second in as many contests following a 10-game stretch during which the catcher didn't log any extra-base hits. However, Naylor still hasn't recorded multiple hits in a contest since July 4, and he's batting just .180 (9-for-50) over 19 games during that span.
