• Chris Coghlan was back in the lineup Wednesday after nearly ripping the nail off the big toe on his left foot. Coghlan was injured when he accidentally kicked his suitcase in his hotel room during the middle of the night. He went to the emergency room at a local hospital for treatment Monday. He did pinch-hit Tuesday, but had to be lifted for a pinch-runner.
• The Cubs will celebrate the 1980s during the next homestand, which begins Friday with an Interleague game against the Rays. On Sunday, the Cubs will wear throwback uniforms from 1988, the year the lights were turned on at Wrigley Field. There will be a first-night bobblehead Friday.
On Aug. 13, it'll be '80s Rock Night, and any fans who show up wearing KISS makeup or Def Leppard branded clothing will have a chance to win tickets to two local shows by the rock bands. It'll also be Zubaz pants night at Wrigley.
All the events are part of Wrigley's 100th anniversary. For information, go to wrigleyfield100.com.
