PHOENIX -- For the second straight day, D-backs outfielder Yasmany Tomás was scratched from the starting lineup. Before Friday's series opener against the Padres, it was announced Tomas was out with stiffness in his upper back.
Tomas missed Thursday's game against the Nationals with a stiff neck after initially being penciled into the starting lineup.
Arizona manager Chip Hale said before batting practice that there was a chance Tomas and/or second baseman Jean Segura would be scratched. Segura left Thursday's game early with a cramp under his left rib cage.
"We've got two guys who are a little bit in flux," Hale said.
Tomas took batting practice on the field but was scratched afterward. He is batting .270 with 30 homers and 80 RBIs in 138 games.
Segura was scheduled to take batting practice in the cage rather than on the field. Segura is batting .320 with 20 homers and 64 RBIs in 150 games. He also has 201 hits, five shy of the single-season franchise record set by Luis Gonzalez in 1999.
