Martin, Bettis making bullpen decisions tricky

SCOTTSDALE, Ariz. -- Rockies right-handed relievers Chris Martin and Chad Bettis turned in impressive innings Friday and could be making bullpen decisions difficult.

Martin, a non-roster invitee obtained from the Red Sox along with pitcher Franklin Morales for infielder Jonathan Herrera, pitched a 1-2-3 eighth inning in the Rockies' 5-0 loss to the Giants on Friday afternoon and has a 3.38 ERA in five appearances. Martin has yet to appear in the Majors.

Bettis, who saw big league time as a starter and a reliever last season, struck out two in an impressive eighth inning of the nightcap against the Mariners -- and has thrown five scoreless innings. Some have speculated Bettis, a second-round pick out of Texas Tech in 2010, could be developed into a closer.

There could be a middle relief spot open if Morales, who has been a reliever most of his career, makes the starting rotation.
