[9] After the blockbuster Turner deal, the Phillies spent the rest of December upgrading their pitching after losing several key pieces to free agency.

[11] On January 7, 2023, the Phillies announced that they had traded outfielder Matt Vierling, utility player Nick Maton and catcher Donny Sands to the Detroit Tigers for relief pitcher Gregory Soto and infielder Kody Clemens.

On January 9, 2023, the Phillies acquired RHP Yunior Marte from the San Francisco Giants, trading away LHP Erik Miller.

Aaron Nola was unable to hold on to a 5–0 lead in game 1 (the start of a season-long struggle for the right-hander); the Phillies went on to lose 11–7.

Visiting the New York Yankees the next day, April 3, Taijuan Walker struggled in his first Phillies start as the team remained winless with a 8–1 loss.

The following day, however, Matt Straham dominated in his first start for Philadelphia, and the bullpen held the game together earning the Phils their first win of the year by a score of 4–1.

A day later, the Phillies were held scoreless until the bottom of the 9th, when they exploded for 3 runs, capped off by a Bryson Stott walk-off single.

Despite leading 4–3 going in to the top of the 9th on Easter Sunday, Seranthony Dominguez was unable to lock down the save, surrendering 3 runs as the Reds won 6–4.

They then beat the Chicago White Sox in a series that included Trea Turner's first Phillies homer before returning home to take on the Colorado Rockies.

Against all odds, they won the series, with Nola and Wheeler dominated in the first two games, capping off a 10–3 run and moving over .500 for the first time all season.

The Phillies blew a 5–0 lead in the final game, with Max Muncy hitting a walk-off grand slam off of Kimbrel to complete the sweep and hand Philadelphia its 4th straight loss as they fell to 15–17.

They won the last 2 games in Washington, and then got fantastic performances from Nola, Taijuan Walker, and Wheeler in a sweep of the Detroit Tigers.

In a back and forth game 1, Kyle Schwarber launched a walk-off solo homer to give the team its season high 6th straight win, and first over LA on the year.
