White Sox backup catcher Tyler Flowers figured he'd have another night off. And then starter A.J. Pierzynski and manager Robin Ventura were ejected in the third inning and suddenly he was in the game. Flowers responded to the quick call Saturday night. He homered to tie the game in the sixth and later had an eighth-inning, two-strike bunt single to set up an important insurance run as Chicago beat the Seattle Mariners 5-4 for its fifth straight win.
