Lopez exited early during his relief appearance in Monday's 3-2 loss to the Royals with right ankle pain, Rich Dubroff of BaltimoreBaseball.com reports. He retired the lone batter he faced and was credited with his second hold of the season.
Pitching for the fifth time in seven days, Lopez lasted just three pitches before departing after he appeared to tweak his ankle while attempting to cover first base. According to Dubroff, Lopez is scheduled to undergo further diagnostic testing Monday, so an update may not be available until Tuesday. Since moving from the rotation to the bullpen Aug. 21, Lopez has given up two earned runs while striking out 10 over 8.1 innings.
