KISSIMMEE, Fla. (AP) _ Shane Reynolds has two bulging discs in his lower back, but the ailments are not expected to affect the spring training routine of the Houston Astros pitcher.

Reynolds, who turns 33 next week, has been experiencing lower back pain throughout spring training and underwent a magnetic resonance imaging exam Thursday.

The MRI showed the two bulging discs, one of which Reynolds said he has known about for 10 years.

``These will be treated with medication and rehab,'' Astros general manager Gerry Hunsicker said Friday.

Reynolds was 16-14 for Houston last year and has been the Astros' opening-day pitcher the past four years.

Another ailing right-hander, Scott Elarton, made his first appearance since shoulder surgery last October, pitching Friday for Triple-A New Orleans against Toledo.

Elarton threw 33 pitches in 1 2-3 innings, allowing four hits and three runs _ just one earned.

``I felt great,'' he said. ``I had pretty good rhythm. Everything felt great and that was what I was looking for today.''

Elarton, 24, was 9-5 for the Astros last season, his first full year in the major leagues. The surgery was to repair a stretched rotator cuff.
