-- During the Baltimore Orioles' day off on Thursday, reliever Steve Kline may have discovered a glitch in his mechanics that might turn around his troubled season. For several hours Kline, who has a 5.55 ERA, sat in his home and watched videos of his delivery from his 1998 season with the Montreal Expos.

"I wanted to see where my hands were," he said. "It was completely different."

After watching much footage, Kline saw that in 1998 he did not lower his hands as much as he does now.

"I didn't have my trigger point, so what happens is my arm drags and it gets slow," he said.

The next day Kline spoke with pitching coach Ray Miller and made an adjustment. The results have been good so far. In the weekend series against the Colorado Rockies, Kline pitched 22/3 scoreless innings and stranded four runners.

"I had better life to my stuff," he said.

Aside from closer B.J. Ryan, who likely will be exclusively used in ninth-inning situations, Kline is the only situational left-hander on the team after John Parrish's demotion last week.

"It's a good time to get consistent," Kline said.

Grimsley Getting Closer

Reliever Jason Grimsley, who had elbow ligament replacement surgery in October, threw again on Monday and could be a week away from a rehabilitation assignment. The team will anxiously watch how Grimsley throws Tuesday, the first time he will have a bullpen session on consecutive days.

"We'll see how he bounces back," Manager Lee Mazzilli said. . . .

Second baseman Brian Roberts returned to the starting lineup after being kept out because of a stiff lower back.
