Tena is not in the lineup for Friday's game against the Cardinals.

Tena has handled most of the reps at third base against right-handed pitching over the last few weeks for the Nationals, but he will begin Friday's festivities on the bench as the Cardinals send righty Erick Fedde to the bump. Amed Rosario is at the hot corner and batting sixth Friday.

Arenado (back) will start at third base and bat cleanup in Friday's game versus the Nationals.

Arenado was a late scratch from the Cardinals' lineup Wednesday due to back spasms, but he's feeling well enough to play following the team's off day Thursday. The veteran third baseman will carry a modest four-game hitting streak into Friday's series opener.

Kemp is slashing .331/.423/.662 with 10 home runs, five steals and a 27.0 percent strikeout rate in 35 games for Triple-A Lehigh Valley.

Kemp has started 19 games at third base, seven games at first base and six games at second base while logging the second-highest wRC+ (184) in the International League. His .419 BABIP illustrates how fortunate Kemp has been in the early going, but he's nonetheless looking ready for his first taste of the majors if the Phillies deal with any injuries to their infield.

Schunk (groin) has resumed baseball activity, MLB.com reports.

Schunk has been sidelined since April 26. He has resumed fielding and batting practice as well as baserunning drills, but a timeline for his return is still unclear.

Bohm went 1-for-4 with a run scored in Thursday's 7-6 extra-inning victory over the Rays.

Through his first seven games in May, Bohm is batting .308 with one home run, one double, four RBI and four runs scored over 26 at-bats. The corner infielder hasn't hit for much power overall in 2025, but he's batting .304 (24-for-79) across his last 21 outings. Bohm began the season in the top half of Philadelphia's lineup, but he'll likely stick in the lower part of the batting order unless he starts to supply more pop.

Rosario went 3-for-5 with a walk, a double, a run scored and two RBI in Wednesday's loss to the Guardians.

Getting the start at third base against southpaw Logan Allen and batting second, Rosario produced his second three-hit effort in his last three games. The veteran infielder has boosted his slash line on the season to .279/.300/.442 with two homers, one steal, nine RBI and 11 runs in 70 plate appearances, but he remains stuck in a timeshare at the hot corner with Jose Tena.

McMahon went 4-for-4 with a home run, two doubles, a walk, two total runs and two total RBI in Wednesday's extra-inning loss to the Tigers.

McMahon and Michael Toglia teamed up to notch all six of the Rockies' extra-base hits Wednesday, though the pair's performance wasn't enough to upset Detroit. McMahon endured an awful start to the season, batting just .147 with a mere four RBI over 29 games through the end of April. However, the veteran third baseman has begun to turn things around in May -- he's hit safely and driven in at least one run in four of five contests this month, and he's notched five extra-base hits (two doubles, a triple and two homers) in that span.

Riley went 1-for-4 with a run scored and a stolen base in Wednesday's loss to the Reds.

Wednesday marked the first stolen base of the campaign and the sixth career steal for the All-Star third baseman. Riley also extended his hitting streak to six games and his on-base streak to 10. Since April 27, Riley is hitting a strong .286 (12-for-42) with two home runs, two doubles, seven RBI and four runs scored.

Reds manager Terry Francona said Wednesday that Candelario (spine) received an epidural to address his lumbar strain, Charlie Goldsmith of the Dayton Daily News reports.

Francona noted that Candelario has made no notable progress in his recovery since landing on the injured list last Wednesday, and the Reds will wait for the injection to take full effect before determining his next steps. Before being shut down with the injury, the veteran corner infielder had gotten off to a miserable start to the season, slashing just .113/.198/.213 with a 31.9 percent strikeout rate over 91 plate appearances.

Reds manager Terry Francona said that Marte's placement on injured list Wednesday was due to a Grade 2 left oblique strain, Charlie Goldsmith of the Dayton Daily News reports.

Marte is eligible for activation May 15, but because he's dealing with a moderate strain rather than a mild one, he will most likely be sidelined beyond the minimum 10 days. A more precise timeline for Marte's return should emerge once he's able to resume baseball activities. Santiago Espinal will start at third base in Wednesday's game against Atlanta and will likely receive the bulk of the playing time at the position while Marte is on the shelf.
