The Blue Jays reinstated Kirk (concussion) from the 7-day injured list Sunday. He'll start at catcher and bat sixth against the Royals.

The backstop had a minimum-length stay on the shelf after being struck on the facemask by a foul tip last weekend. The 26-year-old Kirk will step back in as Toronto's No. 1 backstop after slashing .304/.361/.413 with seven home runs, 47 RBI and 27 runs over 88 games prior to landing on the IL.

Caratini is out of the lineup for Sunday's game against the Red Sox.

Despite bringing his batting average up to .267 with a 4-for-5 performance in Saturday's 7-3 loss, Caratini will head to the bench for the series finale. With Houston acquiring Carlos Correa and Jesus Sanchez at the trade deadline and getting Jeremy Pena back from the injured list Friday, Caratini's playing time may become more inconsistent.

Narvaez is out of the lineup for Sunday's game against the Astros.

Narvaez will get a breather after he caught all nine innings of Saturday's 7-3 win over the Astros. Connor Wong will get the nod behind the plate Sunday, and manager Alex Cora said he planned on having the 29-year-old catch again Monday against the Royals in an effort to keep him sharp, according to Tim Healey of The Boston Globe. Despite the impending time off, Narvaez should still viewed as Boston's No. 1 catcher.

Higashioka went 2-for-4 with a home run, a walk, three total RBI and an additional run scored in Saturday's 6-4 extra-innings win over the Mariners.

Higashioka opened the scoring with a two-run homer in the third inning and broke a 2-2 tie in the 10th with an RBI single. In 17 games since July 4, the veteran backstop has posted a remarkable 1.142 OPS with nine extra-base hits, 14 RBI and 10 runs scored. For the year, he's slashing .269/.316/.431 with seven home runs, 30 RBI, 22 runs scored and three steals across 212 plate appearances.

Perez went 2-for-4 with a solo home run in Saturday's 4-2 loss to the Blue Jays.

The veteran catcher took Max Scherzer deep in the sixth inning, giving Perez his fifth straight 20-homer campaign and the ninth of his Hall of Fame career. The 35-year-old has been getting plenty of work at first base and DH this season to preserve his legs, but with Freddy Fermin now a Padre, Perez might need to be behind the plate more often over the final two months unless the Royals decide top prospect Carter Jensen, who has eight homers in his first 24 Triple-A games, is ready for his big-league debut.

Heineman was removed from Saturday's game against the Royals with a head contusion, Hazel Mae of Sportsnet reports.

Heineman was hit by a pitch in the third inning and took a foul tip off his catcher's mask shortly afterward in the fourth, which ultimately ended his day behind the plate. The team is currently labeling his injury as a contusion, though the 34-year-old backstop will likely be evaluated for a concussion.

Wells isn't in the lineup for Saturday's game against the Marlins, Bryan Hoch of MLB.com reports.

Wells will use Saturday to rest after going 1-for-5 with a run scored during Friday's high-scoring loss. While Wells sits, Ben Rice will catch for starter Cam Schlittler and bat sixth.

Langeliers went 3-for-5 with a two-run home run and a double in Friday's 5-1 win over the Diamondbacks.

Langeliers did his damage early, with the homer coming as part of the Athletics' four-run first inning. He's lifted five long balls over his last seven games, going 12-for-29 (.414) with seven RBI in that span. The hot stretch has the catcher up to a .258/.312/.507 slash line on the year. His .819 OPS is impressive, especially since it was at .709 entering the All-Star break. Langeliers has added 19 homers, 45 RBI, 41 runs scored, five stolen bases and 17 doubles through 80 contests this season.

Higashioka is not in the Rangers' starting lineup against the Mariners on Friday.

Higashioka has started in the Rangers' last three games since returning from a hamstring injury, going 5-for-11 with a triple and two solo homers. He'll get a breather Friday while Jonah Heim serves behind home plate and bats ninth.

The Rays designated Thaiss for assignment Friday.

Despite Danny Jansen being traded to Milwaukee on Monday, the Rays added to their backstop depth by acquiring Nick Fortes from the Marlins and Hunter Feduccia from the Dodgers. Thaiss is slashing .218/.349/.288 with one steal, one home run and 16 RBI in 190 plate appearances this season.
