Worth noting

• Remarkably, Chris Stewart is moving around freely without the aid of crutches only a few days past his Wednesday knee surgery. In fact, he was tentatively planned to begin some running on Monday, until the wet conditions ruled that out.

• The biggest loss with Monday's rainout was the opportunity to hear the Richardson 5 singers, from Lake Wales, Fla., perform the National Anthem. To make up for not being able to take the field, the five youngsters sought refuge from the rain under a canopy outside the Pirates' clubhouse and performed a series of songs that delighted and amazed passersby.

Bryan Morris did some indoor throwing in the batting cages Monday morning, and Jeanmar Gomez and Stolmy Pimentel were also due to throw bullpens.
