Iowa's Steve Clevenger, who is with the team on a rehab assignment, was also ejected. He was not in the game at the time.
GROSSMAN PICKED OFF
After Robbie Grossman hit a double into center field to start off the RedHawks' hitting, he was then picked off at second base by Negrin.
Brett Wallace and Brandon Laird would then single on back-to-back plays after Jose Martinez grounded out. A run by Grossman in the bottom of the first could have made a difference at the end of the game.
HOME SWEET HOME
The RedHawks are now 2-4 in their last week, but hope to turn their fortunes around in their next seven straight games at home.
They are 17-10 at Chickasaw Bricktown Ballpark, and are now a game back behind the Round Rock Express, who they will play a four-game home series against starting Friday.
The RedHawks face the Cubs again at 11 a.m. Tuesday at Chickasaw Bricktown Ballpark. Asher Wojciechowski (2-2, 3.23 ERA) is scheduled to start for OKC, while Guillermo Moscoso (2-3, 4.75) is expected to pitch for Iowa.
