• Pirates third base coach Tony Beasley might be asked to perform more duties in the season's final six weeks. Beasley sang the national anthem before Tuesday's game, and the Pirates exploded (for them) for four runs and a win. Pittsburgh had been held to two runs or fewer in 11 of its previous 12 games, losing all but two.

• Cubs outfielder Tyler Colvin leads all major-league rookies with 19 homers.

• Pirates right-hander Ross Ohlendorf has a damaged muscle in the back of his right shoulder that could sideline him for the rest of the season. An MRI exam on Tuesday revealed a strain that will need recovery time and rehabilitation but will not require surgery.

• Nationals put rookie pitcher Stephen Strasburg back on the 15-day disabled list Tuesday and scheduled him for a further test this week on his strained right forearm. Strasburg was on the disabled list earlier this month with tightness in his right shoulder. This is his first season in the majors after being the overall No. 1 pick in the 2009 draft. The Nationals aren't sure when he will pitch again. He will undergo an MRI arthrogram, where dye is injected into the arm to show contrast, on Thursday.

• Marlins pitcher Ricky Nolasco (torn meniscus in right knee) will have a bullpen session today that should decide whether he is capable of starting again this season.
