[dbacks.com] D-backs aim to improve strong lineup via trade - Things figure to intensify as it becomes more clear which teams are buyers and which are sellers. There's little question in which category the D-backs fall. "This is a strong club," Hazen said. "I do think it has some depth to it. We don't feel the need to go out there and do anything, but we're going to take every opportunity to improve it. I think that's our responsibility." The team's most pressing need looks to be a power right-handed outfield bat. Especially with Yasmany Tomas on the disabled list, the lineup has proven to be vulnerable against left-handed pitchers.
