• After wrapping up their seven-game road trip Sunday in St. Louis, the Phillies return to Philadelphia for an eight-game homestand against the division-rival Marlins and Braves in a pair of four-game series. Philadelphia has struggled at home, going 16-21.
"It's hard to put my finger on it as we speak," Sandberg said when asked about playing better on the road. "If there's a positive to that, we've established that we can play on the road. To carry that over to home when we're playing at home, that would be another positive."
• Catcher Cameron Rupp, ranked as the Phillies' No. 18 prospect, got his first start of the season Sunday. Rupp, who was recalled Friday to add depth after Wil Nieves cramped up Wednesday, appeared in four games for the Phillies last season, hitting .308.
• The Phillies recalled pitcher B.J. Rosenberg from Triple-A Lehigh Valley on Sunday at the conclusion of their seven-game road trip, optioning reliever Ethan Martin back to Triple-A.
Martin had appeared in two games in early June during his stay with the Phillies, most recently pitching June 7. Sandberg said the key behind Sunday's move was getting Martin more innings.
"He needs to go pitch," Sandberg said. "It's just game situational here. The starters have been going [deep] and there's just not enough work for him in the bullpen. So he's just going to stay sharp and to pitch."
Rosenberg was with the team in April, last pitching in the Majors on April 20. In eight appearances he posted a 7.11 ERA, allowing five runs in 6 1/3 innings. He has posted a 2.84 ERA in 12 2/3 innings this season in Triple-A.
Rosenberg will join the Phils as they begin an eight-game homestand Monday.
