Matzek walked two batters in a scoreless ninth inning Tuesday during a loss to the Mets.
The southpaw is having trouble finding the plate right now, issuing five free passes over his last two appearances, but none of the baserunners came around to score. Matzek has a 2.08 ERA but a 1.50 WHIP over his last 10 games, posting an 8:8 K:BB through 8.2 innings during that stretch, and his luck may not hold much longer if he doesn't find a little more control.
