LOS ANGELES -- Questions regarding the July 31 Trade Deadline, the Dodgers' top prospects and more are answered in this week's Inbox.

Which Dodger prospects are "untouchable," and which ones are tradeable?
-- LAD Burner Account, @LADBurnerAcct

If the Dodgers are about to trade any of their top prospects, catcher Keibert Ruiz probably is the one. Catcher is the organization’s deepest position, and 24-year-old Will Smith has already shown he’s MLB-ready. Ruiz, although ranked No. 1 in the system by MLB Pipeline, is younger at 21 and was having his worst offensive season professionally when he was promoted to Triple-A on Sunday. Can’t even imagine a deal that would entice this management to trade away pitcher Dustin May or infielder Gavin Lux.

Is Smith with the big club Tuesday? If not, why did Ruiz get promoted?
-- Zack, @DodgerZack

With the disappointing offensive production of Austin Barnes, it’s tempting to speculate that Ruiz’s Sunday promotion to Triple-A is the first of a chain reaction like you suggest. But that’s probably premature. Ruiz has spent 1 1/2 seasons at Double-A, and his offense last year was better than this year. Maybe he needs a new challenge. It’s also not unprecedented for Ruiz and Smith to be paired on the same team. They were at Double-A Tulsa together last year. Also, if the Dodgers are suddenly willing to include Ruiz in a bigger trade, what better way to elevate his visibility than to give him a promotion?

In 2015, Corey Seager came up in September and was fantastic. Then he made the postseason roster and was not nearly as good. When we bring these studs up in September (Lux, Smith, May, DJ Peters) and they do well, do you see them making the October roster even without the playoff experience?
-- Lucas L., @bbb_mamba

This is why management usually errs on the side of experience in October. Fans were clamoring for Seager to replace an aging Jimmy Rollins, which finally happened in September. But Seager found October baseball an entirely different ballgame. A change at catcher is even trickier, because it can impact an entire pitching staff. Fans now demand Smith to replace Barnes, mostly for offensive reasons. But Barnes is the primary catcher for All-Stars Clayton Kershaw and Walker Buehler, and switching catchers in midseason can disrupt the underappreciated rapport with a pitching staff, which is one of Barnes’ strengths. He deserves as much praise for his work with the pitchers as he does criticism for his bat. And Russell Martin? He’s the personal catcher for Hyun-Jin Ryu. Mess with that battery at your own risk.

Who will they get via trade?
-- The Real Jay Stone, @JaySton87054413

Who will be available? With only one Trade Deadline and a scramble for Wild Card contention, it’s still unclear which teams are sellers or buyers. While the assumption is the Dodgers need a left-handed reliever like the Pirates' Felipe Vázquez or the Giants' Will Smith, what they really seem to need is a right-hander who can dominate right-handed hitters. Neither Pedro Baez nor Joe Kelly have done that this year. That’s why a Daniel Hudson redo makes some sense.

• Latest trade rumors

Any chance they can trade Joc Pederson for some bullpen help?
-- Andy J., @24jacobo

There’s always a chance, depending on your definition of bullpen help. Pederson is a part-time player who already makes $5 million and will be eligible for a significant raise next year in his final season of arbitration. He is a home run hitter who is probably more valuable to the Dodgers than most other clubs. He is primarily a left fielder whose first-base experiment has been, let’s say, a curiously timed challenge. The Dodgers reportedly had Pederson dealt to the White Sox this spring if they had signed Bryce Harper. But he doesn’t profile as the type of inexpensive, controllable player losing teams seek in return when they become sellers. Any team trading an impact reliever (Smith the pitcher, Vazquez, Shane Greene, etc.) will demand in return the Dodgers’ best young players -- Smith the catcher, Ruiz, May or Lux.

I read a while ago that Andrew Toles had arrived finally to the Spring Training complex in Arizona. What is his current status? Have the personal issues been overcome enough that he will play sometime in 2019?
-- Steve W.

Unfortunately, Toles left Camelback Ranch-Glendale after a few weeks of workouts, and the Dodgers have had nothing to say since. From a baseball standpoint, he seems to be completely off the radar.
