The Rockies expect Feltner to take a big step forward this season. Feltner missed most of last season after suffering a fractured skull when he was hit in the head by a line drive off the bat of the Phillies’ Nick Castellanos on May 13.

Pfaadt, who made his major league debut last season, has faced the Rockies once, starting against them on Sept. 5. He took the loss after giving up three runs in 3 2/3 innings. He allowed six hits, struck out four and walked none.
