Chaparro is expected to be called up from Triple-A Rochester, Andrew Golden of The Washington Post reports.

Chaparro is set to join the Nationals in New York ahead of their three-game series against the Mets beginning Tuesday. The 26-year-old missed the first two months of the year with an oblique strain, but he posted a .304 average with five home runs, 19 RBI and eight runs scored over 15 games with Rochester following his return to action May 28. Chaparro will now replace Nasim Nunez on the major-league roster after Nunez was sent down to Triple-A on Sunday.

Alonso went 3-for-6 with two home runs, four RBI and three runs scored in Sunday's 13-5 win over the Rockies.

Alonso launched two-run home runs in the third and eighth innings, marking his second multi-homer game of the week. According to Anthony DiComo of MLB.com, he passed David Wright for second on the Mets' all-time home run list and set the team record for multi-homer efforts with 23. Over his past 15 games, the 30-year-old has hit safely 14 times with five multi-hit performances and 12 extra-base hits. He leads the majors with 61 RBI this season while slashing .301/.396/.594 with 17 long balls and 41 runs scored across 293 plate appearances.

Hiura is out of the lineup for Sunday's game against the Mets.

It's the second straight game on the bench for Hiura, who has gone 2-for-11 with a double and two runs in five games since being added to the big-league roster last weekend. Kyle Farmer is starting at first base Sunday, with he and Hiura each receiving four starts at the position in Colorado's past eight games.

Horwitz is out of the lineup for Sunday's game against the Phillies.

Horwitz will take a seat for the third time in four games while the Pirates go up against another southpaw in Cristopher Sanchez. Jared Triolo will get the nod at first base and should continue to fill the short side of a platoon with Horwitz.

Arraez went 1-for-5 with a double, two RBI and a stolen base in Saturday's loss to the Brewers.

San Diego trailed by two runs with two outs in the ninth inning before Arraez tied the score with a two-run double. The big hit wasn't quite enough to send San Diego home with a victory, however, as Caleb Durbin swatted a walk-off homer for the Brewers in the bottom of the frame. Arraez has reached base safely in each of his first six games in June, though he's batting just .250 (7-for-28) during that span. Arraez's batting average sits at a fine .281 on the campaign, but that's well below his career mark as his three-year streak of winning a batting title looks to be in peril.

Busch went 1-for-3 with a walk and a two-run home run in Saturday's 6-1 win over the Tigers.

The first baseman crushed a Keider Montero changeup 414 feet down the right-field line in the fifth inning, the first of three Chicago long balls off the Detroit right-hander and one of five Cubs homers on the day. Busch has gone yard four times in his last five starts while hitting safely in eight straight games, pushing his slash line on the season to .276/.377/.521 with 10 home runs and 38 RBI in 60 contests.

Encarnacion-Strand went 5-for-10 with two home runs and five RBI between wins over the Diamondbacks on Friday and Saturday.

Friday's game was suspended due to rain, and when it resumed Saturday, Encarnacion-Strand emerged as the hero after smacking the walk-off RBI double in the 10th. He carried over that momentum into Saturday's scheduled game, putting the Reds on the board in the first inning with a three-run shot to left field. Encarnacion-Strand had produced a .482 OPS across 59 plate appearances prior to suffering a back issue and landing on the injured list April 17, but the extended period on the shelf and subsequent rehab assignment may have helped the 25-year-old infielder figure things out at the plate. Expect the Reds to continue to find ways to keep his bat in the lineup now that he's looking healthy and productive.

Naylor (hand/shoulder) is serving as the designated hitter and batting cleanup against the Reds on Saturday.

Naylor was pulled from Thursday's game against Atlanta due to lingering shoulder and hand injuries. He didn't play Friday versus Cincinnati, but he's back in the lineup for Saturday's contest. Naylor is slashing .289/.345/.448 with nine steals, seven home runs and 39 RBI in 255 plate appearances this season.

The Pirates placed Rodriguez (elbow) on the 10-day injured list Saturday.

Rodriguez injured his right elbow throwing a ball to second base while warming up for the second inning of Friday's game against the Phillies. Imaging revealed inflammation in his right elbow, and he will undergo further tests to determine the severity of the injury and an approximate timeline for his return to the majors, per Danny Demilio of PittsburghBaseballNow.com. With Rodriguez and Joey Bart (concussion) both on the injured list, the Pirates promoted Brett Sullivan from Triple-A Indianapolis to serve as the backup catcher behind Henry Davis.

The Phillies placed Harper on the 10-day injured list Saturday due to right wrist inflammation, Lochlahn March of The Philadelphia Inquirer reports.

Harper sat out Friday's matchup versus Pittsburgh due to what was deemed soreness in his right wrist, and he's now set for a longer absence with a diagnosis of inflammation. The move is retroactive to June 6, so Harper will be eligible to return for the first contest of a three-game set against Miami on June 16, though it's unclear at this point if he'll be ready to return then. Philadelphia recalled Otto Kemp from Triple-A Lehigh Valley in a corresponding move Saturday.
