NEW YORK — Even in a walk-off win, the Mets had to hold their breath.

Juan Soto departed New York’s 3-2, 10-inning win over the Detroit Tigers after fouling a ball off the top of his right foot. X-rays were negative, and Soto is day-to-day. The Mets finish their series with the Tigers on Thursday afternoon before welcoming the Yankees to Citi Field for this year’s first edition of the Subway Series on Friday.

Soto fouled a 2-1 pitch from Framber Valdez off an area just below his shin guard in the third inning. Serving as the DH, Soto initially stayed in the game, striking out in that at-bat and grounding out to Valdez in the sixth. But after jogging down the line on the comebacker, he was done for the day.

“It got him pretty good there,” manager Carlos Mendoza said. “You could tell he was in pain. That second at-bat, he didn’t look right.”

MJ Melendez replaced Soto in the seventh.

The negative X-rays represented uncharacteristically good injury news for the Mets, who have already lost four of the nine players in their Opening Day lineup. That includes catcher Francisco Alvarez, who tore the meniscus in his right knee on Tuesday night and landed on the IL Wednesday.

It goes without saying that the Mets, who are piecing together some better play with three series wins in the last four, can’t play too many days without Soto.

After he missed nearly three weeks earlier this season with a calf strain, the Mets planned to ease Soto back into the everyday lineup with some early off-days. But the injuries around him, including one to Francisco Lindor on the night Soto returned, changed that plan. Soto has started all 19 games since his return late last month.
