The Pittsburgh Pirates are giving two youngsters a fair shot at winning the fifth starter spot in their rotation.

Left-hander Jeff Locke and right-hander Kyle McPherson were impressive in their first outings of spring training. Neither got a chance to pitch Tuesday because the Pirates' game against the Baltimore Orioles was rained out. There was no initial indication if there would be a makeup.

The rain gave Pirates catcher Russell Martin a chance to rest. He was scratched from the lineup earlier Tuesday, and he will also sit out Wednesday because of minor soreness in his right shoulder. Martin said it was normal pain for a catcher.

Orioles starter Chris Tillman was pushed back to start Wednesday against the Red Sox.
