Detroit Tigers left-hander Gregory Soto didn't have much of a routine last season.

Whether it was starting, coming out of the bullpen, participating in long toss sessions or lifting weights, he never knew what to expect when his name was called.

His output in the first three months — a 7.46 ERA in 13 games and seven starts — reflected those uncertainties. When he became a full-time reliever in August, his numbers drastically improved for the rest of the season: 2.51 ERA in 14? innings.

"Suddenly, I was a reliever," Soto said Saturday.
