"But it was a good one, man," Santiago said after giving up two runs in 4 1/3 innings to put his spring ERA at 1.64. "It kept its path. It was on the right road. It was definitely a great chase pitch. We almost got [Mark Reynolds] on that check swing [in the second inning]. That was a great pitch for me."
Santiago wants to throw his screwball a lot more often this season, even though he's still a lot more comfortable with his fastball, changeup and slider. The key for the 26-year-old left-hander is to show that he can throw it for a strike.
And by his own count, he's 16-for-17.
"Hey I'm just throwing, man," Santiago said, smiling. "Got it going, got it going."
