Pedro Martinez felt good after a four-inning simulated game Saturday, and the Mets ace is on track to return to the rotation next week. Martinez threw 75 pitches -- 45 in game conditions -- from the Shea Stadium mound on a warm and humid morning in front of the watchful eyes of Willie Randolph and Rick Peterson. Both the braintrust and the right-hander came away pleased, impressed, and relieved by the 30-minute workout session. "First time out felt pretty good, better than I thought," said Martinez.
