Musgrove (elbow) threw 23 pitches in live batting practice Friday, Kevin Acee of The San Diego Union-Tribune reports.
Friday's session was shorter than the 30-to-40-pitch bullpen session he logged last Friday, but it still marks a significant step forward, as it's the first time he's faced live hitters since spring training. He's scheduled to throw against hitters again sometime next week and will likely do so a few more times before beginning an extended rehab assignment.
