Smoak finally heating up

Maybe the M's were beginning to question what they'd received in the Cliff Lee trade. (OK, they were, but it wasn't because of Smoak.) It has been a disappointing year in the majors for the switch-hitting prospect Seattle received from the Texas Rangers in July.

Actually, Smoak, 23, hit a mere nine homers while batting .279 at Triple-A ball this year. He hasn't been anything special versus southpaws, either. But Smoak, 6-foot-4 and 220 pounds, is still developing. With a frame like that, and his superb gap power (he still slugged .497 this season on the farm), he appears to be destined to grow as a power hitter.

Since the M's recalled him, in mid-September, he has played regularly, going 9-for-31 (.290). He punctuated that run with three hits, including a ding dong against left-hander C.J. Wilson, last night against his old club. Only six days left....
