John Isner, who took a wild card into Monte Carlo (where he lost to Ernests Gulbis), talks about his feelings when he heard about the bombings that occurred during the Boston Marathon.
“It's crazy,” Isner told reporters. “I hope whoever was behind it gets caught. It's just horrible to see that there are monsters like that out there really. People like that, unfortunately, all over the world and in the U.S.”
