ARLINGTON -- From the Department of Healing Players:

Reliever Keone Kela is aiming to rejoin the club when the second half starts next Friday at the Chicago Cubs.

Kela worked a scoreless inning on Thursday with Double-A Frisco in his second appearance on injury-rehabilitation assignment. Kela is happy with the velocity on the fastball and the sharpness of the curveball.

Kela is scheduled to take the back-to-back test on Saturday and Sunday with Double-A Frisco. If he handles that, the likely next step is a return to the active roster. Kela has been on the disabled list since April 21 because of an elbow impingement, which required surgery.

First baseman Mitch Moreland missed his sixth consecutive start because of tightness in his right calf. Manager Jeff Banister hopes to get Moreland into the lineup before the All-Star break. The club continues to believe Moreland will avoid the disabled list.

BRIEFLY: The Rangers acquired left-hander Eric Jokisch from Miami in exchange for minor-league infielder Pedro Ciriaco and assigned him to Triple-A Round Rock. Jokisch, 26, had four appearances, including one start, with the Chicago Cubs in 2014. Jokisch relies on a change-up and guile. ... Left-hander Derek Holland began a throwing program on flat ground. Holland has been on the disabled list since June 22 because of shoulder inflammation. ... Catcher Robinson Chirinos, whose career was almost ended by concussions, reported no problems after taking a hard foul ball off the mask on Thursday. Chirinos credited improvements in the protective mask. ... The Double-A Frisco club will auction various game-related items to raise funds for the ``Assist the Officer Foundation,'' which helps fallen members of the DART and Dallas Police Department forces.
