The Toronto Blue Jays are beginning to chirp about chasing first place in the American League East. The next step in that pursuit will come Friday night when they open a three-game series against the visiting Chicago White Sox. The Blue Jays stumbled with a 9-5 loss to the Arizona Diamondbacks on Thursday afternoon in the finale of a three-game set after winning the first two games of the series, which opened a six-game homestand. The loss left the Blue Jays in third place in the division, three games removed from the first-place New York Yankees.
