The Arizona Diamondbacks may soon be looking to trade Mark Trumbo.

Jake Lamb, who plays third base, is expected to return from injury by late next week, which creates some roster issues.

Yasmany Tomas would have to move into the outfield, perhaps pushing Trumbo onto the trading block.

However, Dave Stewart says he's in no rush to trade Trumbo, who ranks second on the club in home runs.

"I think we've just got to evaluate our situation, see what we're doing, where we're going," Stewart said. "We know there's interest in Trumbo. But in fairness to him, we don't really know at this point what Tomas is going to be. He's playing well, but he only has one homer.

"With all of our players, if you overwhelm me with something, I've got to listen. I guess most people would say the trade deadline is where we'll find the best value. But at this moment, Mark Trumbo is my guy. He gives us something in our lineup that none of our other guys do other than Goldschmidt – a guy who can hit the ball out of the ballpark. (David) Peralta does when he plays. But right now, our main home run threats are Goldschmidt and Trumbo."
