Del Castillo is not in the lineup for Tuesday's contest in Miami.

Del Castillo cracked a grand slam and drove in six runs in the series opener versus the Marlins on Monday, but he'll receive some rest a day later. Jose Herrera will do the catching for the Diamondbacks.

Stallings is absent from the lineup for Tuesday's contest versus the Nationals.

Drew Romo will start at catcher while Stallings hits the bench Tuesday. Stallings and Romo have now received two starts apiece since the latter joined the major-league roster following Elias Diaz's release, and the two seem likely to continue splitting catching duties down the stretch.

Giants manager Bob Melvin said Saturday that Murphy (knee) has begun a hitting and running progression and could be an option to return from the 60-day injured list in September, MLB.com reports.

Murphy has been on the shelf since May 5 with a left knee injury that was categorized as between a Grade 1 and Grade 2 sprain. The backstop hasn't recovered from the injury as quickly as anticipated, but he seems to be responding better after visiting Dr. Neal ElAttrache in Los Angeles in late July and receiving a platelet-rich plasma injection for the knee. The Giants likely won't be able to pinpoint a more precise target date for Murphy's return until he's cleared to begin a minor-league rehab assignment.

Bailey (side) said after Monday's 5-3 win over the White Sox that he was scratched from the lineup for precautionary reasons, Andrew Baggarly of The Athletic reports.

The Giants are labeling Bailey as day-to-day with right side tightness, but the catcher's comments imply that he's avoided an oblique strain. Still, Bailey could be given another day off Tuesday, in which case Curt Casali would be in line for a start behind the plate.

Fortes went 2-for-3 with a solo home run and a sacrifice fly during Monday's 9-6 loss to the Diamondbacks.

Fortes' streak of at-bats without a home run came was snapped at 139 when the catcher tagged Brandon Pfaadt for a solo shot in the third inning. In three games since being activated from the injured list, Fortes is 3-for-9 with three RBI. He's slashing .223/.247/.308 with three home runs across 240 plate appearances this season.

Del Castillo went 2-for-4 with a grand slam and a two-RBI single during Monday's 9-6 win over the Marlins.

Del Castillo's excellent rookie campaign got even better Monday, as he delivered his first career grand slam as part of a six-RBI day. The 24-year-old has homered in back-to-back games and is slashing .333/.405/.668 through 37 plate appearances. Del Castillo has been working on the strong side of a platoon with Jose Herrera behind the dish, and with Gabriel Moreno (adductor) not close to returning, Del Castillo should continue to see plenty of catching work.

Alvarez went 1-for-3 with a solo home run during Monday's 4-3 win over the Orioles.

Alvarez took Seranthony Dominguez yard on a 3-0 pitch with one out in the bottom of the ninth inning, breaking the 3-3 tie and giving New York the victory. Alvarez is 10-for-44 (.227) with a home run and a triple in August.

Herrera (shoulder) has gone 8-for-19 with a home run, a stolen base and two walks in five games since returning to the Triple-A Memphis lineup Tuesday.

Herrera was held out for a little over a week earlier in the month while recovering from a left shoulder sprain, but he's since been given the green light to return and has looked dialed in at the dish. He's now slashing .345/.457/.448 through eight games in August.

Bailey has been scratched from the starting lineup for Monday's game against the White Sox due to tightness in his right side, Shayna Rubin of the San Francisco Chronicle reports.

Bailey is likely headed for additional testing to determine the severity of the injury. Curt Casali will handle the catching duties and bat ninth in Bailey's absence.

Feduccia was called up from Triple-A Oklahoma City on Monday.

Feduccia will officially join the major-league roster, replacing Austin Barnes (toe) as the team's backup catcher after Barnes was placed on the 10-day injured list Monday. Feduccia has produced a .282 average with six home runs, 46 RBI, 38 runs scored and two stolen bases over 252 at-bats in 73 games with Triple-A Oklahoma City this season.
