Castellanos said Friday that he would "really welcome" playing first base, if asked, MLB Network reports.

EDGE Analysis

Castellanos has never played first base before and has been a full-time right fielder since 2018. However, he came up through the minors as a third baseman and that was his primary position through his first five seasons in the big leagues, so he's not foreign to the infield. Castellanos is set to make $20 million in 2026 in his final year under contract with the Phillies, but the expectation is he will be either traded or released by Philadelphia this offseason.

Castellanos went 1-for-4 with a double and an RBI in Game 4 of the NLDS against the Dodgers on Thursday.

EDGE Analysis

Castellanos started each of the final three games and went 2-for-15 with five strikeouts in the series. Despite the poor overall numbers, he delivered a key knock in Thursday's loss by doubling in the seventh inning to give the Phillies a lead. Castellanos is entering the final year of his current contract with the team, but he could be a trade candidate or otherwise have a change of scenery this offseason after managing only a 90 wRC+ across 589 plate appearances in 2025.

Castellanos isn't in the lineup for Saturday's game against the Dodgers, Charlotte Varnes of The Athletic reports.

EDGE Analysis

After slashing .250/.281/.385 across 57 plate appearances in the final month of the regular season, Castellanos will retreat to the bench for the first game of the Phillies' postseason run. Max Kepler will start in right field and bat seventh.

Castellanos went 2-for-3 with a two-run home run and an additional RBI in Friday's 8-2 win over the Diamondbacks.

EDGE Analysis

The homer was Castellanos' first in over a month -- his last homer was Aug. 17 versus the Nationals. The outfielder has gone 17-for-64 (.266) over his last 20 games while occupying a short-side platoon role for much of that time. He's now at 17 homers, 69 RBI, 71 runs scored, four stolen bases and a .255/.299/.411 slash line across 140 contests.

Castellanos is not in the lineup for Friday's game in Miami.

EDGE Analysis

Castellanos has now been absent from the lineup each of the last three times the Phillies have faced a right-handed batter, as he appears to have fallen into a short-side platoon. He's slashing only .199/.253/.309 since the All-Star break. Max Kepler will start in right field and bat seventh for Friday's series opener.

Castellanos is not in the lineup for Thursday's game in Milwaukee.

EDGE Analysis

Castellanos picked up two hits and scored two runs in Wednesday's loss to the Brewers, but he'll find himself on the bench Thursday for the fourth time over the last 10 contests. Brandon Marsh, Harrison Bader and Max Kepler will form the Phillies' outfield trio in Thursday's series finale.

Castellanos is out of the lineup for Monday's game in Milwaukee.

EDGE Analysis

Castellanos has gone hitless over his last five contests and continues to see a dip in playing time since the Phillies acquired Harrison Bader at the trade deadline, as Monday marks the sixth time that he's been out of the lineup since Aug. 1. Philadelphia will go with Brandon Marsh, Bader and Max Kepler in the outfield for the series opener.

Castellanos isn't in the lineup for Thursday's game against Atlanta, Lochlahn March of The Philadelphia Inquirer reports.

EDGE Analysis

Castellanos will take a seat for the first of four games against Atlanta after going 0-for-6 with three strikeouts and a walk during Philly's last series against the Mets. Brandon Marsh, Harrison Bader and Max Kepler will make up the Phillies' outfield trio Wednesday against right-hander Cal Quantrill.

Castellanos is out of the lineup for Monday's game against the Mets.

EDGE Analysis

Castellanos got off to a rough start to August, but his bat began to heat back up over the past week, with the 33-year-old going 9-for-24 with a solo home run, two doubles, two walks and seven runs over his past six starts. The Phillies will still send Castellanos to the bench for the second time in five games, with Harrison Bader entering the lineup in center field and getting flanked by Brandon Marsh in left and Max Kepler in right.

Castellanos is absent from the lineup for Wednesday's game against the Mariners.

EDGE Analysis

Castellanos will head to the bnech for the third time in 11 games. He had been out of the lineup just twice this season prior to that, once due to disciplinary reasons and once due to a minor injury. The Phillies will go with Brandon Marsh, Harrison Bader and Max Kepler in the outfield Wednesday.
