Extra bases

• Classic rock tunes -- not typically the genre of choice among today's ballplayers -- were playing at a healthy decibel in the Cubs' clubhouse Monday, with legendary groups such as the Eagles, the Steve Miller Band and Steppenwolf blaring in the hours leading up to game time. The starting pitcher usually picks the tunes to play on the day he's pitching, and Jeff Samardzija, a classic rock aficionado, was clearly in control of the stereo on this particular day.

• Rain postponed Monday's game, but the rest of the week looks good in Cincinnati (or so say the forecasts). On Tuesday, there is only a 30 percent chance of rain, and Wednesday looks even better, with chances of rain estimated at 20 percent.

• The bullpen will enter Tuesday's game looking to put up zeros for the fourth consecutive game. If successful, it would be the first time the relief corps had four scoreless games since last July 25-28, totaling 9 1/3 innings.
