On a 93-degree Wednesday afternoon at Coors Field, tempers boiled over between the visiting Red Sox and Rockies. Colorado right-hander Cal Quantrill escaped a jam in the fourth inning by getting Reese McGuire to fly out to center fielder Brenton Doyle for the third out. Quantrill, a demonstrative player, pumped his arms to celebrate and then exchanged heated words with McGuire as McGuire ran up the line. UPDATE: Rockies blast Red Sox for four homers in record-tying 20-7 win The two players moved toward each other, and players from both benches and bullpens rushed onto the field.
