BOSTON — Contact hasn’t been Mark Vientos’ problem lately as much as driving the ball.

The Mets third baseman/DH began Monday a respectable 16-for-54 (.296) in May, but with only two extra-base hits for the month.

Vientos homered against the Cubs on May 11 and followed with a double the next night against the Pirates.

Vientos acknowledged that he’s currently not hitting as many home runs, as he went hitless in a recent game against the Red Sox. He anticipates going through a phase where he consistently makes solid contact with the ball.

Vientos last season blasted 27 homers in 414 at-bats. He entered Monday with five in 158 at-bats.

Manager Carlos Mendoza expressed his desire for Vientos to focus on having a quality approach at the plate rather than solely aiming for home runs. He emphasized the importance of controlling the strike zone, making good contact, and trusting that the home runs will come naturally, despite the inconsistency in performance.

Mendoza played down the significance of facing formidable opponents like the Yankees, Red Sox, and Dodgers in a series of games. The Mets faced the Yankees and lost two out of the three games in their last series.

“I feel like nowadays there’s no soft spot anymore,” Mendoza said. “It seems like every team you play is a good team, especially in the National League. It’s a pretty competitive league.”

The Mets will play next week against the White Sox and Rockies, who began the day a combined 49 games below .500.

Nick Morabito and Jonah Tong were named Eastern League Player of the Week and Pitcher of the Week, respectively, for Double-A Binghamton.

Morabito, a 22-year-old outfielder, was 12-for-26 (.462) with a 1.248 OPS for the week.

Tong, who earned the award for the second straight week, threw six scoreless innings against Hartford in which he struck out eight and walked two with two hits allowed.

The Mets have not lost three straight games this season.

The 48-game stretch without losing three straight is the team’s longest since 2007, when the Mets went 56 games into the season without such a losing streak.
