Kohl Stewart, their $4.5 million bonus baby, had to leave the game in the top of the second inning with what could be a recurrence of the shoulder ailment that landed him on the Disabled List for 19 days recently.
The Kernels rallied for a 5-3 victory over Quad Cities before 1,678 fans at Veterans Memorial Stadium, but Stewart looked dejected as he left the mound after conferring with Cedar Rapids Manager Jake Mauer, pitching coach Ivan Arteaga and the Kernels trainer.
"It's frustrating," Stewart said in the locker room. "It didn't feel right the first inning, but I tried to get through it. We'll see what happens."
Stewart was placed on the DL from July 25 through Aug. 13 with an "impingement" in his right shoulder. He pitched four strong innings against Beloit Aug. 13 and looked good, according to Mauer, but Stewart struggled from the outset Tuesday.
