Md., on Thursday, so that could be another possible destination for Harper.

Wednesday marked exactly one month since Harper played his last big league game, after which bursitis in the knee put him on the disabled list. After Harper hit a bloop double and drew a walk on Tuesday, his second game offered the opportunity to increase his comfort level at the plate.

In his second at-bat against Myrtle Beach right-hander Jerad Eickhoff, Harper worked a 3-1 count, then dug out an offspeed pitch low in the zone and sent a towering shot high into the overcast sky. Right fielder Jake Skole drifted farther and farther back, but eventually ran out of room as the ball completed its long descent over the wall.

"It was a 3-1 changeup, and obviously hehis final at-bat, when the foul ball nailed his foot. Harper bent over at the waist with his hands on his knees as Daubach and Potomac's trainer went to him. After a minute, Harper gathered himself and stepped back to the plate, then left after completing his at-bat.

"Unfortunately, that happens a lot in baseball," Daubach said. "It was right off the inside of his foot and it hurt for a while, but it went away. He was scheduled to go six innings anyhow, so get some treatment, get some rest, and he'll be back at it tomorrow."
