Rollins, who has the second-most plate appearances in 2012 of any National League player, is unsure whether he'll play again in 2012. He tested the sore calf with some grounders during batting practice.
He thought it prudent to rest Monday, and perhaps longer, to avoid something larger. Rollins called his rest "precautionary."
"So if I get a day off here, or take two and see what's it's like on the third day, then let's do that," Rollins said. "With the number of games left, that has less to do with it as opposed to, if I do something going into an offseason where I injure myself when it can be prevented right now."
Rollins has 699 plate appearances this season; only Miami's Jose Reyes has more. It's his most since 2009. He has a career-high 62 walks and a .743 OPS, his best since 2008.
He also leads the team with 23 home runs. That's a power output he has not achieved since the MVP season of 2007. It does not make Charlie Manuel wonder whether Rollins' run production would be better served lower in the batting order.
The manager made an interesting comparison between Rollins and a top free-agent-to-be.
"Jimmy can hit third. He can hit fifth. He can hit in other places in the lineup," Manuel said. "He can lead off of course.
"A month ago, when we're talking about getting [Michael] Bourn for a leadoff hitter, Rollins got more production. Bourn might have a little higher average, but Rollins has more production. So which one would you rather have in your leadoff hole?"
Entering Monday, Bourn's OPS was .742 and mostly driven by on-base percentage. Rollins' .743 was fueled by slugging percentage.
The Phillies will use the bullpen for all nine innings Tuesday, with reliever B.J. Rosenberg starting. Rosenberg started six games at triple-A Lehigh Valley but has pitched solely in relief with the Phillies.
Righty Tyson Brummett joined the team Monday and is expected to chew up some innings. He was fetching coffee with his wife Sunday at home in Salt Lake City when Phillies director of player development Joe Jordan called.
"OK, something is up," Brummett said. "I'm getting released, traded."
Instead it was a surprise promotion for a 28-year-old who spent time at double A and triple A in 2012. He posted a 3.20 ERA in 90 innings while mostly a reliever.
Michael Martinez started at shortstop in Rollins' place. Kevin Frandsen batted first, making him the fifth different leadoff hitter for these Phillies. Rollins, Juan Pierre, Shane Victorino and Nate Schierholtz were the others. . . . When Brummett debuts, he will be the eighth Phillies player in 2012 to see his first major-league action. That would be the most since 1996, when 15 made their debuts. . . . No Phillies players were among MLB's most-sold jerseys since the all-star break. Derek Jeter topped the list.
