Last night’s low Class A game at Wrigley Field between Peoria and Kane County was historic for a couple of reasons. The game set a Midwest League single-game attendance record as over 32,000 fans entered the Friendly Confines to take in the first minor league game in the park’s history. The game would be suspended in the ninth inning due to rain with the score tied 6-6, but the most important on-field news was an injury suffered by Athletics first-round pick Jemile Weeks in the first inning.

In the first at-bat of the game, Weeks hit a grounder to short and injured himself when he stumbled over first base trying to beat the play out. He had to be helped off the field and was taken out of the game. The injury was believed to be a hip flexor, but Weeks will be re-evaluated after an MRI today.

Weeks, 21, had gotten off to a slow start in his pro career after Oakland made him the draft’s 12th overall pick, getting only one hit in his first five games. But he turned that around with a 10-game hitting streak starting on July 14. He hit his first professional home run on July 24, and was hitting .297/.422/.405 through his first 74 pro at-bats.
