Now here’s your not-quite-conventional summary of Tigers draft pick Calvin Drummond, who could toss a couple of lengthy innings in the time it takes to digest his background: He is 23 years old and has been drafted four times. He has attended, or at least been enrolled at, four colleges: Arizona State, Orange Coast Community College, University of San Diego and Arizona Christian. He is 6-foot-4, 210 pounds, throws right-handed, and — explaining the Tigers’ interest — he throws a fastball 90-96 mph, with a curveball, as well as a hard slider, and a change-up that scouts will testify breaks in two directions. “The timeline is interesting,” said Brian Reid, the Tigers area scout who has monitored Drummond since he was a high school pitcher in Huntington Beach, Calif. “But you can be absolutely right about his talent. He’s got an outstanding arm, with power stuff.” The Tigers grabbed Drummond in the sixth round (186th overall) of this month’s baseball draft and, until further notice, will make him a starter now that he is among their newly signed. But now, about that crazy resume … Drummond began innocently enough, as an Arizona State recruit who discovered upon arrival in the desert that he was caught in a numbers/scholarships quagmire. He transferred to Orange Coast, pitched there, then sat for a year at San Diego, where he pitched for a season until transferring to a school whose new coach he had long known: Doyle Wilson, who had worked as an assistant coach at Southern Cal. Drummond was ready to pitch last autumn when he was declared ineligible for reasons that have been kept private. The Tigers know the story and weren’t any more bothered in taking Drummond this year than three other clubs had been when they selected Drummond in earlier drafts: Brewers (34th round in 2008), Nationals (34th round 2011) and A’s (38th round, 2012).
