The debut will come. Until it does, Terry Collins tries not to dive too deep into the results of Zack Wheeler’s minor league games.

"No," Collins said. "I’ve got enough on my plate right now. I can’t keep track of everybody in the organization. I know how he pitched.

"We all keep saying, ‘He’s on the way. He’s on the way. He’s on the way.’ Well, he’ll pitch his way here. And when that time is, I have no idea. But I didn’t get on the Internet last night to see how he was doing. I was worried about who we play today."

Wheeler pitched six innings of one-run ball in Class AAA Las Vegas’ 2-1 win over Fresno late Saturday night. He showed better control – six strikeouts, one walk – than he had in other starts, improving to 4-1 with a 3.86 ERA.

If and when Wheeler elbows his way into the rotation (think mid-June), Collins will have to decide which chess piece to remove — likely Dillon Gee or Jeremy Hefner.
