Smith hit a solo homer as a pinch hitter in a 4-3 win against the Padres on Wednesday.

Smith began the contest on the bench, continuing his regular routine of resting every three games. However, the star backstop was called upon to pinch hit with the game tied 3-3 in the bottom of the ninth inning and came through with a walk-off solo shot to right-center field. Smith extended his on-base streak to 10 games with the blast, and he's batting .378 with three home runs, 10 RBI and 11 runs scored over that stretch. As a pinch hitter this season, Smith has gone 4-for-7, and he's batting a robust .333 overall on the campaign to lead the National League.

Maldonado is not in the Padres' starting lineup against the Dodgers on Wednesday.

Maldonado will sit after going 1-for-4 with a double across the first two games of the series. Elias Diaz will serve behind home plate and bat eighth while catching pitches from Stephen Kolek.

The Giants reinstated Bailey (neck) from the 10-day injured list Wednesday, Shayna Rubin of the San Francisco Chronicle reports.

Bailey needed only a minimum stint on the injured list to recover from a neck strain. Logan Porter was optioned to Triple-A Sacramento in a corresponding move and Andrew Knizner will serve as the backup catcher now that Bailey is back in the mix.

The Giants optioned Porter to Triple-A Sacramento on Wednesday, Alex Pavlovic of NBC Sports Bay Area reports.

Porter was brought up from Triple-A last week when Patrick Bailey hit the IL with a neck strain. Now that the latter is healthy, Porter will return to the minors, where he's slashed .237/.350/.319 across 161 plate appearances this season.

Murphy is out of the lineup for Wednesday's game against the Mets.

Murphy had started both of Atlanta's last two games, marking the first time he's been behind the dish for consecutive contests since May 27 and 29. The veteran backstop has produced a .487 OPS thus far in June, so he doesn't seem to have built much momentum toward overtaking Drake Baldwin as Atlanta's No. 1 catcher. Though Baldwin will get the start Wednesday, he's also started to slow down at the dish following a hot start to the season, so the playing time between him and Murphy could be distributed in fairly equitable fashion for the foreseeable future.

Davis is out of the lineup for Wednesday's game against the Tigers.

Davis' brief run as the Pirates' No. 1 backstop appears to have come to an end after Pittsburgh activated Joey Bart from the 7-day injured list Tuesday. Bart will make his second straight start behind the plate Wednesday, while Davis takes a seat for the third game in a row after he had previously received a breather in Sunday's loss to the Cubs before Bart was activated.

Alvarez is absent from the lineup for Wednesday's contest in Atlanta.

Luis Torrens will do the catching and bat sixth as the Mets try to even the series. Alvarez went hitless in Tuesday's game and is 1-for-14 over his last four tilts.

Stephenson is absent from the lineup for Wednesday's game versus the Twins.

Stephenson will get a routine day off after he started the last four contests, with three coming at catcher. Jose Trevino will replace him behind the dish and bat sixth.

Moreno (hand) is out of the lineup for Wednesday's game against the Blue Jays.

Jose Herrera will draw another start behind the dish while Moreno takes a seat for the third game in a row as he continues to manage a sore right hand. The Diamondbacks haven't called up another catcher from the minors, so Moreno is likely being viewed as day-to-day and could make his return to the lineup as soon as Thursday's series finale.
