SURPRISE, Ariz. -- Promising left-handed pitching prospect Sean Manaea, the 34th overall pick of the 2013 Draft, is hoping to get back on the mound again sometime next week.
Manaea, the No. 2 prospect in the Royals' system and the No. 6 lefty pitching prospect in baseball, per MLB.com, has been slowed this spring by an abdominal strain and just started throwing long toss again this week.
"It has been frustrating," Manaea said. "But the main thing now is to get better, take it slow and not hurt it worse."
Manaea had a solid season last year at Class A Advanced Wilmington, where he posted a 3.11 ERA and struck out 146 hitters in 121 2/3 innings.
Manaea, who is 6-foot-5 and 235 pounds, had been hoping to impress the Royals' coaching staff this spring, but he suffered the strain about two weeks ago.
"There's really nothing you can do about it," he said. "Those things happen."
Manaea hopes to be back throwing competitively by early April, at the latest.
