Diamondbacks: C Welington Castillo was not in the starting lineup after being hit by a pitch on the left elbow on Monday, the second time in three games he was hit on the same elbow. "It's just unfortunate, luckily last night he had a pad on it and cushioned a little bit the force of the hit," manager Chip Hale said before Tuesday's game. "But, it was the exact same spot." ... After the game, Hale announced right-hander reliever Randall Delgado will be placed on the DL with an ankle injury and former closer Addison Reed will be recalled from Triple-A Reno on Wednesday.

He will be making his fifth major league start after missing all of 2014 following Tommy John surgery.
Mariners: Right-hander Felix Hernandez (12-5, 2.69 ERA) is tied for the A.L. lead in victories, but after going 8-1 in April and May, is 4-4 in his last 10 starts. In two starts since the All-Star break, he is 1-0 with 1.38 ERA, allowing two earned runs in 13 innings. Wednesday's start will give him the team record with 324 career starts, moving past Jamie Moyer.
