The Indians have granted right-hander David Aardsma his release, tweets MLB.com's Jordan Bastian. Aardsma asked for his release after being informed that he would not make the big league bullpen, according to Bastian.
The 32-year-old Aardsma returned from a lengthy Major League disappearance to fire 39 2/3 innings of 4.31 ERA ball for the Mets last season. Prior to that stint, Aardsma had thrown just one inning from 2011-12 as he battled back from Tommy John surgery. In New York, he averaged 8.2 K/9 and 4.3 BB/9 but posted a low (even by his standards) 32.8 percent ground-ball rate.
Aardsma doesn't have the zip he had prior to Tommy John, when he averaged better than 94 mph on his fastball with regularity. He checked in at an average of 91.2 mph last season but still posted a strong 11.7 swinging-strike rate. Aardsma stranded 80.5 percent of his baserunners last season — a mark he is unlikely to repeat — but also was plagued by a 14.6 percent homer-to-flyball ratio, which figures to come down (his career mark is 9.5 percent). For what it's worth, Aardsma has had a strong Spring Training, yielding two earned runs on five hits with five strikeouts and no walks in six innings of work.
