Manager Matt Williams said Rendon's thumb is better than it was Friday, when he left the game in the top of the sixth inning. He hurt it while committing an error two innings earlier on a ball hit off the bat of Carlos Quentin. X-rays on Rendon's thumb were negative.
"He is doing contrast treatment -- ice and heat--flushing some blood out of there," manager Matt Williams said. "It a little swollen. Pretty sore. We have a quick turnaround tomorrow. We have to see how it is. The good news is, there was no fracture. It's better than last night, not as much swelling as there was yesterday, but it's still sore."
