Washington outfielder Bryce Harper had surgery on his injured left thumb on Tuesday and will be out for an extended period of time.

Manager Matt Williams would not commit to a time frame, but said “that time frame is out there” after reports Monday that he would be out until at least July.

“The doctor reported that everything went fine, and we got a little message from Bryce about getting back and taking BP post-surgery,” Williams joked.

“It went fine, we’ll have to see how long it takes ... we expect him to heal fast. Given his history, he has healed pretty fast. We are optimistic about it, but we’re not really sure how long it is going to take.”

The two-time All-Star was placed on the 15-day disabled list on Sunday with what was then called a sprained left thumb.

The 21-year-old Harper is batting .289 with one home run and nine RBIs this season.

CHAPMAN THROWS BATTING PRACTICE — Cincinnati Reds closer Aroldis Chapman threw 25 pitches during batting practice Tuesday, passing the final test before he can begin rehabilitation in the minors.

Chapman likely will pitch at Class A Dayton on Thursday in his first time in a game since suffering a head injury. He’s hoping to be activated after four or five appearances in the minors.

“It went very good,” Chapman said, with trainer Tomas Vera translating. “All my pitches were the way I wanted.”

The left-hander was hit on the forehead by a line drive during a spring training game in Arizona on March 19. He had a plate inserted above his left eye and nose to help fractures heal. Chapman was one of eight Reds who opened the season on the disabled list, the most in the majors.

Jonathan Broxton is closing games in his absence.

MINOR BACK WITH BRAVES — Atlanta Braves left-hander Mike Minor is set to pitch in the major leagues for the first time this season. Braves manager Fredi Gonzalez says Minor will start Friday night at home against San Francisco.

The 26-year-old Minor has been slowed by shoulder soreness this season. He’s pitched five times in the minor leagues during rehabilitation games at three different levels.

“We just wanted to make sure Mikey was healthy,” Gonzalez said before Tuesday night’s game at Miami. “But he feels good.”

Minor had urinary tract surgery on Dec. 31, delaying his spring schedule. After the shoulder soreness developed, he was shut down in spring training.

Minor went 13-9 with a 3.21 ERA last year. He pitched a career-high 204 innings and led the team with 181 strikeouts.

SURGERY FOR GRIFFIN — Athletics right-hander A.J. Griffin is scheduled to have elbow surgery today, and will miss the entire season with fellow third-year starter Jarrod Parker.

Griffin was 14-10 with a 3.83 ERA last season after making his major league debut in 2012.

He will have the surgery after getting a second opinion from Dr. Thomas Mehlhoff in Houston.
