Lopez to make D-backs debut Sunday

SCOTTSDALE, Ariz. -- Cuban free-agent pitcher Yoan Lopez will make his Cactus League debut Sunday against the Giants at Salt River Fields at Talking Stick.

Lopez, who was given an $8.7 million signing bonus this offseason, has had a little trouble with his command during bullpen sessions this spring.

With that in mind, the D-backs had the 23-year-old throw 25 pitches in a simulated game Wednesday to make sure he would be ready for Sunday.
