The right side of the Mets’ infield was anything but consistent in the first half.

Pete Alonso went hitless in five of his last six games before the All-Star break, finishing in a 2-for-23 funk with a homer, two walks and 11 strikeouts to close out the first half.

It was a rocky first three-plus months for the first baseman, who made the All-Star team despite what would be a career-low .807 OPS, as well as an average of .211, but he also has 26 home runs, second in the National League only to Atlanta’s Matt Olson.

If the Mets are going to mount any kind of second-half rally to make the postseason, Alonso will have to lead the way, and they’ll hope for better production from Jeff McNeil, who seems to be among the handful of hitters adversely impacted by the shift ban.

McNeil was shifted against just 22 percent of the time a year ago, but his weighted on-base percentage was actually higher with teams shifting him (.397) than it was when they didn’t (.356).

The second baseman’s struggles, though, go deeper than any potential impact made by the shift.

His production against all pitches has decreased since he won the batting title a year ago. That .326 average was propped up by hitting into some good fortune, and that luck hasn’t carried over into 2023.

The Mets can hardly afford to lose Tommy Pham for an extended period of time, as evidenced by the tear he went on for the final six weeks of the first half, so the fact he was listed as day-to-day on Wednesday was no doubt a relief.

Pham left the team’s final game before the break with right groin tightness, but over his final 34 games before the All-Star break, Pham went 40-for-121 with 11 doubles, a triple, six homers and a .987 OPS after compiling just a .627 OPS over the season’s first two months.

The 35-year-old forced himself into the everyday lineup and went from a potential trade chip due to lack of production to a player teams would seek out to provide a second-half boost.

But the Mets are not yet sellers, as they open the second half Friday against the Dodgers at Citi Field seven games back of the Phillies for the last wild-card spot in the NL.

Pham has a .931 OPS in 56 postseason plate appearances and last played in the playoffs in 2020 with the Padres.
