Mets manager Terry Collins believes there's ''no doubt'' Johan Santana (shoulder) will be ready to pitch the season opener. Santana allowed just an unearned run over 2 2/3 innings in his start Sunday against the Marlins. "I truly believe we're going to do this right,'' Collins said. ''Johan Santana will be on the team on Opening Day.'' Santana hasn't reported any issues with his surgically-repaired shoulder thus far. He struck out two batters and got five groundouts today.
