Hunter Pence felt tightness in his right groin Monday night while on rehab assignment, a potential setback that could prevent the Texas Rangers’ outfielder/designated hitter from playing next week in the All-Star Game.

Pence, who was placed on the 10-day injured list June 17 because of the groin issue, will be evaluated by the Rangers’ medical staff Tuesday, and he could still play a second rehab game Tuesday night at Double A Frisco.
