Still in the early stages of recovering from surgery to repair a ligament in his left thumb, Bryce Harper will visit a specialist in Cleveland next week to determine his progress, Manager Matt Williams said.

Harper remains on track for now, having removed stitches from his hand and moved into a brace. Harper has been lifting weights and running. On Friday afternoon, he ran sprints on the Nationals Park warning track.

“He can do everything except let that thumb go,” Williams said.

Harper declined comment.

As for other injuries:

>>> The Nationals remain confident Adam LaRoche will return May 25, after a minimum of 15 days on the disabled list. Today, LaRoche did exercises in a pool to test his strained right quad.

>>> Right-hander Ross Ohlendorf, on the 60-day disabled list with a right lumbar strain, came to Nationals Park on Friday to meet with coaches. On Wednesday, Ohlendorf got creamed in his first rehab assignment, allowing seven earned runs in 2 1/3 innings at Class A Potomac. Williams said Ohlendorf had his usual velocity, but struggled with command.

>>> Taylor Jordan, a member of the Nationals’ opening day rotation, is gathering himself nicely at Class AAA Syracuse. Jordan’s velocity dropped to the high 80s as he went 0-3 with a 5.61 ERA in five starts. After taking nearly two weeks off to work on his motion, Jordan has allowed one run in 11 innings over two starts in the minors. Williams said Jordan’s fastball hummed at 92 to 94 mph on Thursday night, in line with his performance last season and an important development. Jordan fired six scoreless innings.
