Rosario has made noticeable improvement with his receiving. But if teams remember the struggles and are running because they want to take advantage, it's fine with him.
"Maybe they know about what I've done, maybe not," Rosario said. "I hope they don't and they'll keep running."
Rosario, who hit his fourth homer of the season Saturday off Padres starter Edinson Volquez in the second inning and then threw out Everth Cabrera at third for the third out in the third inning, was proud because Friday was not a good night offensively -- he struck out twice in key situations, although he did drive in a run on a fielder's choice -- so the team needed his defense.
"That's one of the best experiences I can have," Rosario said. "I want to be a winner. Not every time are you going to hit. The only thing you can control is your glove -- catching everything, blocking balls, stopping runners."
