KISSIMMEE, Fla. — Tom Glavine knows the end of his career is in sight and he wants to leave on his own terms.

The Atlanta Braves lefty pitched three pain-free innings against his former team in his first start this spring, allowing only two hits Saturday in a 12-1 win over the New York Mets.

Glavine had thrown a simulated game Monday and said he felt as though he’d be ready to join the rotation in about a month.

The two-time Cy Young Award winner has 305 wins, but he started a career-low 13 games last year, going 2-4 before his season was cut short due to elbow surgery. Glavine, who will turn 43 on Wednesday, contemplated retirement but said he wasn’t quite finished.
