KANSAS CITY -- Mike Sweeney could hoist his son, Mini-Mike, after the game, but only with his right arm. His left arm was aching.
Sweeney, the Royals' captain and first baseman, suffered what was diagnosed as a sprained left wrist and sprained left elbow in Wednesday night's 3-1 victory over the Dodgers.
Sweeney was scheduled to have X-rays and perhaps an MRI on Thursday to determine the extent of his injuries. He was just hoping there were no broken bones.
Until then, it's uncertain how long Sweeney could be out of the red-hot Royals' lineup.
"It could be a day, it could be four weeks," he said. "We don't know."
In the fourth inning, Sweeney was catching a throw from third baseman Mark Teahen when batter Jayson Werth, racing toward the bag, clipped Sweeney's glove and wrenched his left arm.
"It was going to be a bang-bang play," Sweeney said. "Unfortunately, I didn't complete it. Mark did a good job -- a great play."
Shouting in pain, Sweeney immediately fell to the ground clutching his arm. He was attended to by assistant athletic trainer Frank Kyte before finally getting to his feet.
"My wrist jammed and I popped my elbow," Sweeney said. "He didn't do it on purpose."
Sweeney had just returned to the lineup on Tuesday night after missing five games because of a strained oblique muscle in the right side of his rib cage.
Teahen had rushed in for Werth's soft roller and made a quick throw to the home-plate side of first base. Sweeney had to reach into the basepath and couldn't avoid the collision.
"I keep him in my prayers," winning pitcher Jose Lima said. "It was kind of tough. If he had stepped out of the baseline, he'd probably get him out. But you know Sweeney. He's a tough man."
The play was ruled a single with an error on Teahen, allowing Werth to reach second base. Werth would come around to score the Dodgers' only run.
Manager Buddy Bell noted that Sweeney returned to the dugout in the last three innings to lead the clamor for a fourth straight victory.
"He's important for us, to be in our lineup and in our clubhouse," Bell said.
