Pedro Martinez is staying patient with his rehabilitation from shoulder surgery. The Mets' ace made 50 throws from about 60 feet on flat ground Tuesday and said he's on schedule to throw four times a week. The three-time Cy Young Award winner increased his distance from approximately 40 feet a week ago. "Everything feels better," Martinez said. "Sleeping feels better. I can roll onto my arm, lay on my side." Still, he won't predict when he'll be back on the mound. He's simply not looking that far ahead.
