They officially signed the largest sports contract in sports history. Miguel Cabrera , the first/third baseman for the Tigers, signed an unbelievable ten-year, $292 million deal. The Tigers can't be happier, since Cabrera is an 8-time All-Star and a rare winner of the Triple Crown. Troy Tulowitzki. Eager to hang onto their All-Star shortstop, in 2010 the Colorado Rockies signed Tulowitzki, 26, to an additional contract over seven seasons – a deal that means Colorado has guaranteed Tulowitzki (see pictures) a huge payout through 2020. The 13-year, $325 million deal is now the largest contract in US sports history. Under the terms, starting in the 2015 season, Giancarlo will earn an average of $25 million per year for 13 years. That's roughly $155,000 per game, $40-50,000 per at-bat (assuming an average of 3 or 4 at-bats per game).
