Contreras (hand/wrist) exited Tuesday's contest against the Pirates in the bottom of the fourth inning, Danny Demilio of PittsburghBaseballNow.com reports.

Contreras was struck in the left hand/wrist by a 99.3 mph fastball from Paul Skenes to open the top of the fourth, ultimately remaining in the game for the rest of the Cardinals' time at-bat. The 33-year-old was replaced at first base by Alec Burleson while Garrett Hampson entered the game in right field. More information on the status of Contreras will likely come in the near future.

Naylor (neck) is batting cleanup as the designated hitter Tuesday against the Giants.

The 28-year-old slugger sat out the previous three games due to neck stiffness, but he's back in the lineup in a non-defensive capacity Tuesday versus San Francisco. Pavin Smith is starting at first base with Naylor easing his way back into the starting nine.

Smith went 2-for-4 with a double and a run scored in Monday's 4-2 loss to the Diamondbacks.

Smith singled in the second inning and added a double in the seventh before coming around to score. With that, the first baseman delivered his first multi-hit performance since June 13. The 30-year-old has been out of the lineup in five of the club's last eight games, losing playing time at first base to Wilmer Flores. Smith appeared in 19 games in June after signing a one-year contract with San Francisco on June 4, slashing .281/.368/.404 with eight RBI, six runs scored, four doubles, one home run and one stolen base across 68 plate appearances.

Horwitz went 2-for-4 with a solo homer and a two-RBI double in Monday's 7-0 victory over the Cardinals.

The Pittsburgh first baseman launched his first career leadoff homer when he took St. Louis starter Erick Fedde deep on the second pitch. Horwitz then returned in the third to lace a two-RBI double off Fedde to notch his second two-bagger of the season. The former Blue Jay has settled into a strong-side platoon role and is now slashing .258/.324/.383 with two homers, 17 runs scored and 14 RBI across 142 plate appearances in 36 games.

Naylor (neck) remains out of the lineup for Monday's game against the Giants.

Naylor will miss a third straight start after exiting Friday's game versus the Marlins with neck stiffness. He is considered day-to-day. Pavin Smith will serve as the Diamondbacks' first baseman and Lourdes Gurriel will be the designated hitter in Monday's series opener.

Triolo is out of the lineup for Monday's game against the Cardinals.

Triolo was included in the lineup in three of the Pirates' previous four games, but the bulk of his starts are still expected to come against left-handed pitching when Pittsburgh has all of its core infielders available. Most of the 27-year-old's value to the Pirates derives from his ability to play all four infield spots, as he's been an easy out at the plate with a .167/.260/.280 slash line over 152 plate appearances on the season.

Kemp is out of the lineup for Monday's game against the Padres, Lochlahn March of The Philadelphia Inquirer reports.

Since being called up from Triple-A Lehigh Valley on June 7, Kemp had started in all but one of the Phillies' ensuing 20 games, but he'll likely find himself on the bench against right-handed pitching more frequently after Philadelphia reinstated Bryce Harper (wrist) from the injured list Monday. The right-handed-hitting Kemp should continue to see regular playing time against left-handed pitching, likely occupying the short side of a platoon in left field with the left-handed-hitting Max Kepler.

The Phillies designated Buddy Kennedy for assignment Monday.

The transaction clears a spot on the active roster for Bryce Harper's (wrist) return from the 10-day injured list. Kennedy went hitless in seven at-bats for the Phillies and hadn't started a game in nearly a week.

The Phillies activated Harper (wrist) from the 10-day injured list Monday. He will start at first base and bat third in the Phillies' series opener versus the Padres.

Harper will return to the Philadelphia lineup after missing the last three-plus weeks with right wrist inflammation. The 32-year-old did not go out on a rehab assignment, but the Phillies were convinced of Harper's readiness by how he looked against live pitching over the weekend.

Hernandez went 1-for-4 with a two-run home run in Sunday's 5-1 win versus the Royals.

The veteran utility man started at first base and gave the Dodgers a 2-1 lead when he took Kansas City starter Kris Bubic deep in the second inning. The long ball marked the first in June for Hernandez, who entered this contest with an anemic .119/.196/.167 slash line across 46 plate appearances in 23 games this month. Through 177 total plate appearances, the 33-year-old is slashing .206/.273/.388 with 23 runs scored and 22 RBI in a short-side platoon role.
