(MLB.com Chicago Cubs)

A pitcher can be a former National League Cy Young Award winner, like the Cubs` Jake Arrieta. Or he could be a rookie with some accomplishment, like the Rockies` Antonio Senzatela, 22. Either way, early efficiency is key. They`ll face each other Sunday in the finale of a four-game series at Wrigley Field.
