The fastest aging segment of the Jays' clubhouse demographic has become the bullpen, many of them signed or acquired this off-season. Sure, that balances nicely with a young starting rotation, but along with unflappable veteran savvy comes unpredictable veteran bodies and nagging injuries from overused parts. On Tuesday, manager John Farrell revealed two of his key relievers, Frank Francisco and Octavio Dotel may be iffy for opening day. Beware the Ides of March. Neither Francisco's 31-year-old right shoulder nor Dotel's 37-year-old left hamstring are considered serious issues in terms of carrying deep into the regular season, but with two weeks to go, each seems serious enough to threaten his presence on the Jays' roster when games begin in earnest. "(Francisco) came in (Monday), threw long-toss, threw a short (15-pitch) pen," Farrell explained. "While warming up in his last outing, he felt some tightness in his right (pectoral muscle). Not in the shoulder, in the right pec. We shut him down. He's improved, but we're going to work him through some long toss and continue on the flat ground.
