The Nationals were swept by the Cubs on Sunday, but that's not what had pitcher Tanner Roark upset.
The Cubs walked Nationals right fielder Bryce Harper six times and also hit the 2015 National League MVP in Sunday's 4-3 win. Three of the walks were intentional.

Roark, who struck out seven and allowed just one run on four hits in six innings, said the Cubs were afraid to pitch to Harper.
"I think it's scared baseball," he told reporters, adding he was "very, very surprised" the Cubs did not give Harper anything to hit.
