NEW YORK (CBSNewYork) — It’s been a painfully quiet offseason for general manager Sandy Alderson and the Mets.

The GM struck quickly in free agency, signing outfielder Michael Cuddyer to a two-year, $21 million deal on November 10.

But since then, the Mets have only signed one player — reserve outfielder/first baseman John Mayberry Jr. — to a major league contract.

Alderson hasn’t made any trades, and his other signings have been minor league deals. But he still believes that his club can win 90 games and reach the playoffs for the first time since 2006.

“We won 79 games last year, which was an improvement over the year before,” Alderson told the MLB Network. “We need to take a bigger jump next season. One of the reasons we’ve been quiet in the offseason is that we have quality players at every position.”

New York’s starting rotation — which was excellent in 2014 — should be even better with the return of ace Matt Harvey, who missed all of last season after undergoing Tommy John surgery. Curtis Granderson and David Wright are expected to bounce back offensively, and Alderson is banking on the continued development of Travis d’Arnaud, Lucas Duda and Juan Lagares.

“We’ve got players with the potential to improve us by 10 games, which is what we need,” Alderson said. “And so we’re comfortable going into spring training; and excited, actually, to see those players and see what kind of step forward they take, and whether that can translate into 10 or 12 games for us in the ‘won’ column.”
