Royals ink 16 First-Year Player Draft choices

ANAHEIM -- Sixteen of the Royals' 50 selections in this week's First-Year Player Draft have agreed to contracts, the club announced on Friday.

Among them were right-handed pitchers Aaron Brooks, the ninth-round pick from Cal State-San Bernadino, and Matthew Murray, the 10th-round choice from Georgia Southern University.

Others signed thus far include: outfielders D'Andre Toney (14th round), Terrance Gore (20), Gabriel Gray (35) and Tyler Chism (43); shortstop Nicholas Cuckovich (17); right-handed pitchers Andrew Ferguson (18), Ali Williams (34), Christian Witt (36), Andrew Durden (38) and Julio Morales (45); left-handed pitcher David Middendorf (22); catchers Lance Harper (23) and Travis Lane (41), and third baseman Mark Threlkeld (25).

O'Sullivan could begin rehab assignment soon

ANAHEIM -- Sean O'Sullivan might soon join fellow starting pitchers Bruce Chen and Kyle Davies on the rehabilitation trail.

"He's throwing and feeling good and I imagine he'll go on a rehab pretty quick," Royals manager Ned Yost said.

O'Sullivan is out with right biceps tendinitis.

Tentatively, Davies (right rotator cuff) will make his second rehab appearance on Sunday or Monday and Chen (left lat) will make his second on Monday, both for Triple-A Omaha. Each of them pitched two innings last Wednesday for Double-A Northwest Arkansas.

If all goes well, Davies and Chen are likely to return to the Royals' rotation by the following weekend. In that case, the starting assignments will undergo a shuffle.

"We've got some decisions to make," Yost said.
