St. Louis Post-Dispatch wrote:The same foot pain that led first baseman Albert Pujols to receive ultrasound therapy twice last winter has resurfaced, causing La Russa to suggest that Pujols may get several games off later this month to undergo additional treatment. Pujols began experiencing soreness in his left foot during last weekend's series against the Washington Nationals, according to La Russa. Plantar fasciitis, an inflammation of the tendon beneath the foot, has caused Pujols increased discomfort since the club arrived in Houston. Head trainer Barry Weinberg said doctors would evaluate Pujols during the coming home stand, and a time may be set for him to undergo a procedure that typically sidelines him for three or four days. If Pujols was in pain, he didn't allow it to slow him in the Cardinals' two-run rally in Saturday's fourth inning. He singled to center and made an aggressive turn toward second. After advancing on a groundball, Pujols took third on a Clemens pitch that short-hopped catcher Brad Ausmus. Breaking on contact, he scored on So Taguchi's groundball as third baseman Morgan Ensberg made a poor throw home.
I think the last part is the most important. He can play through pain.
