Tom had "nasty" stuff for a lot of years. A lot of the pitchers at that time utilized the "drop and drive" method, but none as good as he did.
Quick Tom story- my roommate at Pawtucket faced him in a spring training game in Winter Haven. My roomie said the first pitch was a spring training fastball that he hit about 400 feet, but it was foul. He said Tom looked at him like, who the hell are you kid? The next two pitches were knee high on the outside black for strikes at 95 mph. He said Tom just looked at him and grinned, like welcome to the big leagues kid.
