Holland to begin rehab assignment Wednesday

ARLINGTON -- Derek Holland is finally going to pitch in a game. Holland, who has been sidelined since undergoing offseason surgery on his left knee, is scheduled to begin his medical rehabilitation assignment with two innings for Double-A Frisco on Wednesday.

Holland was back with the Rangers on Saturday. He threw in the bullpen and will go through a fielding workout on Sunday. It won't be too strenuous but if that goes well, Holland will throw another bullpen on Monday and be ready to begin his rehab assignment.

"We just want to get him out there moving around and see what he looks like," manager Ron Washington said.

The Rangers are going to start out slowly with Holland even though he has been throwing up to 80 pitches in his bullpen sessions. He may pitch well enough to convince the Rangers to accelerate his timetable but he could get at least four to five starts in the Minor Leagues before he is ready to return to their rotation.

Right now the Rangers are going with a rotation of Yu Darvish, Colby Lewis, Nick Tepesch, Nick Martinez and Miles Mikolas. Jerome Williams did a terrific job on Friday night against the Athletics, holding them to one run in six innings, but the Rangers have not decided when he'll pitch again. Mikolas pitches on Saturday and Darvish, Martinez and Lewis are scheduled in the three-game series against the Yankees.

"[Williams] deserves another start," Washington said. "But until that time comes, we'll just wait and see. He is still here."

Worth noting

• Left-hander Andrew Faulkner, who was 10-1 with a 2.07 ERA in 21 games, including 18 starts, at Class A Myrtle Beach, has been promoted to Double-A Frisco.

• Triple-A Round Rock reliever Phil Klein has not allowed a run in his last 32 1/3 innings. During the streak, opposing hitters are 9-for-41 off him. He has nine walks and 41 strikeouts.

• Williams was the 31st pitcher used by the Rangers this season, a new club record. Nate Adcock has yet to pitch in a game but he would be No. 32.
