TAMPA, Fla. — The Yankees finally had their squad in full Tuesday.

Centerfielder Jacoby Ellsbury, excused from the first two days of workouts because of the birth of a child, arrived here Monday night and was in uniform for the afternoon workout at Steinbrenner Field.

“Obviously, he’s a couple of days behind,” Joe Girardi said. “But his wife Kelsey is great, the baby’s great, that’s what we talked about today. But physically he looks good.”

Ellsbury, 33, entering the fourth year of a seven-year, $153-million deal, has been mostly a disappointment the first three years of his contract, producing a .264/.326/.382 slash line.

He is among the veterans general manager Brian Cashman has mentioned must produce more this season.

Severino staying, for now

Luis Severino has committed to play for the Dominican Republic in next month’s World Baseball Classic but, unlike teammate Dellin Betances, won’t be leaving camp March 5 to join the team.

“I’m focused on winning my [rotation] spot,” Severino said.

Severino does plan to join the Dominican club should it advance to the semifinals.

Tanaka ahead of schedule

Masahiro Tanaka will make his spring debut next Tuesday in a split-squad game against the Tigers at Steinbrenner Field. The righthander did not make his first start of spring training last year until March 6 as he was brought along slowly after undergoing surgery to remove a bone spur in his elbow. With no physical concerns about the pitcher this year, Girardi announced him as his Opening Day starter on the first day of camp.

Extra bases

CC Sabathia, the No. 2 or No. 3 starter, looked strong in a bullpen session . . . Jon Niese, signed to a minor-league deal Sunday to compete for a reliever spot, threw his first bullpen . . . RHP Ronald Herrera, who finished last season with Triple-A Scranton/Wilkes-Barre, will be out at least two weeks with inflammation in his right shoulder. LHP James Reeves, a 10th-round pick who finished last season with Double-A Trenton, will be out 3-4 weeks with a sprained ligament in his elbow, Girardi said . . . The Yankees traded LHP Richard Bleier to the Orioles for a player to be named.
