Mets’ season-high 11 walks underscore worsening problem: ‘Frustrating’

The Mets allowed a season-high 11 walks in Thursday’s 7-6 loss to Oakland , and though it was the pitching staff’s worst command performance of the season, it’s not a new problem.

They lead the National League in walks allowed and against the A’s, all six pitchers called upon by manager Carlos Mendoza issued at least one walk.

“We’ll continue to dig in deep to see what’s going on,’’ Mendoza said. “When we struggled early in the year, that was one of the issues: too many non-competitive pitches. Today was not a good day.”

It started with Jose Quintana, who gave up four walks in four innings, which contributed to the left-hander throwing 92 pitches in the brief outing.

Huascar Brazoban gave up two walks in his lone inning of work, as did Phil Maton in his — although Maton wasn’t hurt by them in his scoreless frame.

“When you give up walks and have a lot of deep counts, teams are gonna make you pay,’’ Mendoza said. “We’ve got to go back and make adjustments quickly.”

Quintana called his outing “frustrating,’’ especially since he was given an early 5-0 lead and he took the blame for the defeat, saying it was “on me.”

The game took 3:45, making it the longest nine-inning game since MLB began using the pitch clock.

Oakland closer Mason Miller has garnered plenty of attention with his ability to regularly eclipse 100 mph, and he did so again Thursday, earning his first two-inning save, as he finished off Oakland’s win with three strikeouts.

“He’s got a good arm,’’ said J.D. Martinez, who struck out to open the bottom of the ninth on three pitches, a four-seamer that was clocked at over 99 mph and then back-to-back sliders. “He throws 102. He’s a closer for a reason and they used him for two innings. They really wanted to win this game.”

Luis Torrens’ two-run single was the catcher’s latest bit of success with the bases loaded.

He’s 10-for-22 with 24 RBIs in his career with the bases loaded.

Mendoza said Sean Reid-Foley’s shoulder is “fine, structurally,” but the team shut down the right-hander for a few days to “make sure it’s stable.”

No more scans are scheduled on the shoulder.

Reid-Foley has been sidelined with a right shoulder impingement for nearly two months.

Mendoza said the hope was Reid-Foley would begin throwing again in a matter of days.

Christian Scott has been playing catch, according to Mendoza, but the right-hander on the IL with a strained UCL has yet to advance to throwing with intensity.

Kodai Senga (left calf strain) is “doing upper body stuff, but there’s not much to report.”

The Mets signed outfielder Eddie Rosario to a minor league deal and assigned him to Triple-A Syracuse.

The lefty-swinging 32-year-old was most recently with the Braves, where he played 24 games before being granted free agency.

He began the season with Washington and was released in July.

In 319 plate appearances on the year, Rosario has just a .531 OPS, but he was more effective just last year with the Braves when he slugged 21 homers.

The Mets have plenty of outfielders, so it’s unlikely Rosario plays much of a role — if any — in Queens, but he could be an alternative to Ben Gamel or DJ Stewart.
