TORONTO — The worm finally turned. During the Rockies’ painful and sluggish start to the season, manager Bud Black insisted that the offense would wake up. It did, with a vengeance, in a 12-4 throttling of the Blue Jays on Friday night at Rogers Centre. In their first-ever win in Toronto — they went 0-9 here in three previous trips — the Rockies pounded out 20 hits, including leadoff homers by Nolan Jones and Ezequiel Tovar.
