Phillies first baseman Ryan Howard is out of Monday's lineup with left knee soreness, MLB.com reports.
Howard also missed three games in May with soreness in the same knee. Howard is hitting a robust .357/.442/.643 in June without missing a game, so there aren't any indications he's been slogging through this injury the whole month. Most likely, the Phillies are taking extra precautions with the soreness due to last month's issue.
