They're only making weak contact, and one resulted in a shoulda been DP and a ground out to 2B. I wouldn't say Peralta and Heyward's balls were weak contact but I guess if he keeps the ball on the ground it will be hard to be too upset.
Just wanted to point out that if Bourjos was on the Cubs, there's no way he would be playing today, let alone make a nice running catch in the gap to open the game after looking like he was headed for the DL yesterday.
