Mack (hamstring) has gone 3-for-15 with 10 walks, two RBI and two runs in six games since being reinstated from Single-A Jupiter's 7-day injured list July 22.

Mack was on the shelf for nearly two months due to the hamstring strain before returning to action for the Marlins' Single-A affiliate. The 19-year-old catching prospect has shown a hyper-patient approach at the plate since being activated, and his combination of high on-base percentages and burgeoning pop could make him an interesting fantasy option down the road, especially if he's able to stick behind the plate.

Serven went 1-for-4 with a solo home run in Sunday's 7-3 loss to the Dodgers.

Serven will be happy to put July behind him -- he went 3-for-37 (.081) with a home run, a double, four runs scored and a 3:8 BB:K in 12 contests this month. That poor performance at the plate mostly erased the gains he'd made in June to earn a split of playing time with Elias Diaz, and it appears Serven is more or less back to a backup role. He's slashing .225/.295/.382 with four homers, 10 RBI, 12 runs scored, two doubles and a triple in 112 plate appearances this year.

Bart is out of the lineup for Sunday's game against the Cubs, Susan Slusser of the San Francisco Chronicle reports.

Austin Wynns will step in behind the plate for Bart, who went 2-for-10 with a solo home run while starting in each of the past three contests. Though Bart is currently operating as the Giants' No. 1 catcher, he could fall into more of a timeshare by the end of the week if Curt Casali (oblique) is cleared to return from the injured list.

Gomes is out of the lineup for Sunday's game against the Giants.

Gomes had caught three of the Cubs' last four games, but he'll take a seat in the series finale while Willson Contreras checks in behind the plate after having previously seen more opportunities at designated hitter coming out of the All-Star break. Contreras is a prime candidate to get moved ahead of Tuesday's trade deadline, so Gomes could soon have the No. 1 catcher's role all to himself.

Cartaya was removed from Sunday's game with High-A Great Lakes due to an apparent injury, Eric Stephen of SBNation.com reports.

Cartaya suffered the injury while attempting to block a pitch while catching, and he left the field with an athletic trainer. The 20-year-old is one of the Dodgers' top prospects and has a .279/.407/.529 slash line in 36 games since being promoted to High-A at the start of June.

Diaz is out of the lineup for Sunday's game versus the Dodgers, Patrick Saunders of The Denver Post reports.

Diaz is 7-for-22 with a home run and eight RBI since the All-Star break and will receive Sunday off. Brian Serven will work behind the plate in the series finale against Los Angeles.

Delay is not in the lineup for Sunday's game against the Phillies.

Delay will take a seat Sunday for the second time in the past three games. Tyler Heineman will work behind the plate and bat ninth.

Nido is out of the lineup for Sunday's game at Miami, Anthony DiComo of MLB.com reports.

Nido started all seven games since the All-Star break and will take a seat after posting a .770 OPS during that span. Patrick Mazeika will start behind the plate and bat ninth Sunday.

Knizner is out of the lineup for Sunday's game against the Nationals.

Knizner will get a much-needed breather after he started behind the plate in each of the past six games. Austin Romine will relieve Knizner of catching duties in the series finale, but both players are likely to settle into reserve roles as soon as Tuesday, when No. 1 backstop Yadier Molina (knee) is expected to be activated from the injured list.

Herrera is out of the lineup for Sunday's game against Atlanta.

Herrera had started two of the Diamondbacks' previous three contests, but he's still the team's clear No. 2 catcher on the depth chart behind Carson Kelly, who re-enters the lineup for the series finale. Unless he enters Sunday's contest off the bench, Herrera will finish July with a .150/.261/.150 slash line.
