PORT ST. LUCIE, Fla. — Kodai Senga’s original three-week timetable without throwing has been extended by another seven to 10 days, Mets president of baseball operations David Stearns announced on Friday.

That could keep the Mets’ ace out until mid-May.

Senga, who has a posterior capsule strain in his shoulder, will have more medical tests when the seven-to-10-day period is over, Stearns said. If the tests give positive news about the inflammation in the shoulder, Senga will be able to begin a throwing program.

Stearns said Senga has not suffered a setback, just that the original three-week timetable was “our best guess at the time of diagnosis . . . Time frames are our best understanding, our best suggestion. I’m always going to try to provide time frames.  But sometimes it’s going to be shorter. Sometimes it’s going to be longer. In this case, it’s probably about a week longer than we had anticipated on the front end.”

Prospects party

A team of Mets prospects beat Nationals prospects, 4-2, in the first-ever Spring Breakout game for the two teams.

Dom Hamel started for the Mets and allowed one run in two innings. Ryan Clifford, Kevin Parada, Jeremy Rodriguez and Vincent Perozo had RBI hits for the Mets in the seven-inning contest.

“It was really cool just to be one of the first to be in the Spring Breakout, especially for the Mets,” said righthander Calvin Ziegler, who closed out the victory. “It was really fun.”
