Tena (thumb) had X-rays come back negative after leaving Sunday's game against the Angels and is dealing with a fingernail issue, Spencer Nusbaum of The Washington Post reports.

The 23-year-old made his second straight start at third base Sunday but exited during the fourth inning when he was struck in the right hand by a hard grounder. Tena has avoided a serious injury and should be considered day-to-day.

Muncy (oblique) went 1-for-2 with a double, a walk and an RBI in a rehab game with Triple-A Oklahoma City on Saturday.

Muncy performed well in his first game action since May 15. The third baseman is working his way back from an oblique injury and subsequent rehab that progressed slowly and at times was described as "stagnant." He'll need at least a handful more games in the minors to knock off some rust before the Dodgers are ready to bring him back from the 60-day injured list.

Candelario is not in the lineup for Sunday's game against the Brewers.

Candelario will sit after going 0-for-3 on Saturday to end a seven-game hit streak. Jonathan India will serve as the designated hitter while Santiago Espinal starts at second base.

Rivera is out of the lineup for Sunday's game against the Padres.

Rivera's absence is his fourth in Miami's past six games, with both of his starts during that stretch coming against left-handed pitchers. Jake Burger is receiving more run at third base and Jesus Sanchez at designated hitter, which has opened up right field for Derek Hill, though the latter two have swapped those positions Sunday.

Tena was removed in the fourth inning of Sunday's game against the Angels due to an apparent right thumb injury, Mark Zuckerman of MASNSports.com reports. He went hitless in his lone at-bat before departing.

Making a second straight start at third base after he went 2-for-4 with two RBI in his Nationals debut Saturday, Tena's day was cut short when he took a hard grounder off his throwing hand. The play went down as an error, and Tena was immediately lifted from the game in favor of Ildemaro Vargas while his thumb was bleeding profusely. The Nationals should have an update on Tena's condition later Sunday.

Vargas is out of the lineup for Sunday's game against the Angels.

After making five consecutive starts, Vargas now finds himself on the bench for the second day in a row, with both absences coming against right-handed pitching. Though the Nationals optioned Vargas' main competition for playing time at third base, Trey Lipscomb, to Triple-A Rochester on Saturday, the club called up Jose Tena in a corresponding move. Tena will get his second straight start at the hot corner Sunday and looks like he'll be given a look as an everyday player while Vargas shifts to a utility role.

Tena went 2-for-4 with two RBI in Saturday's 5-4 extra-inning win over the Angels.

Picked up as part of the package the Nationals got from the Guardians for Lane Thomas, Tena was promoted from Triple-A Rochester earlier in the day and was immediately plugged into the starting lineup at third base. The move paid off when the 23-year-old walked it off in the bottom of the 10th inning with an RBI single to left-center field that likely would have gone for extra bases had there been any need for Tena to keep advancing. He has a .284/.342/.478 slash line through 100 games at Triple-A this season with 18 homers and 15 steals, and with Trey Lipscomb having flopped in his latest audition, Tena figures to get a long look, either as the regular starter at the hot corner or in a super-utility role.

Vargas is not in the starting lineup for Saturday's game against the Angels, Spencer Nusbaum of The Washington Post reports.

Vargas will begin Saturday's contest in the dugout after going 0-for-4 with one strikeout in Friday's 3-2 win over the Halos. Jose Tena will make his Nationals debut at third base while Nasim Nunez returns to the lineup at shortstop.

Tena is starting at third base and batting sixth in Saturday's game against the Angels, Spencer Nusbaum of The Washington Post reports.

Tena was recalled from Triple-A Rochester earlier Saturday, and he will make his first start for the big club since being acquired from the Guardians on July 29. In the minors this season, Tena is batting .287 with an .824 OPS, 18 home runs and 68 RBI over 448 plate appearances.

The Nationals optioned Lipscomb to Triple-A Rochester on Saturday, Spencer Nusbaum of The Washington Post reports.

After being recalled by the Nationals on July 6, Lipscomb slowly saw his playing time dwindle as he struggled to a .152/.211/.182 slash line with a 23.6 percent strikeout rate across 71 plate appearances. With Ildemaro Vargas establishing a regular role at the hot corner, Lipscomb will go back down to Rochester, where he will have an everyday role at third base. Jose Tena was recalled from Rochester in a corresponding move.
