While the Pittsburgh Pirates and the St. Louis Cardinals have been busy splitting the first two games of a weekend series, they also are doing a lot of juggling with their rosters.
Those rosters will be somewhat different Sunday at PNC Park than they were Friday.
Pittsburgh (28-23) on Saturday activated center fielder Starling Marte (strained right oblique) from the disabled list and returned infielder Jose Osuna to Triple-A Indianapolis. In a 4-1 loss Saturday, Marte slid back into this No. 3 spot in the lineup and hit a solo homer, with struggling right fielder Gregory Polanco moving to seventh.
