With less than a week until Monday’s trade deadline, the Boston Red Sox are still expected to make more moves to bolster the roster for the stretch run in what’s expected to be a tight American League playoff race. That’s particularly important now that newly acquired infielder Curtis Mead has landed on the injured list with a broken left wrist.With that in mind, we opened the mailbag for questions. In Part 1, we dug into the job chief baseball officer Craig Breslow is doing, Curtis Mead’s fit with the team, payroll projections, the rotation, bullpen trades and more.In Part 2 here, we’ll look at more deadline scenarios, the rise of Franklin Arias, prospects who might be traded, Chad Tracy and more.Questions have been lightly edited for clarity.Is there any consideration for promoting Franklin Arias to the big leagues this season? Marcelo Mayer never hit like Arias in the minors. Maybe that’s the shortstop fix, and they spend their trade capital on a catcher or reliever? – Anonymous UThe Red Sox promoted Arias to Triple-A Worcester last week, so while it’s not out of the question he’d be promoted by the end of the season, it might be a bit aggressive for the 20-year-old. Arias hit .318 with a .993 OPS in 77 games this season at Double-A, where he was among the youngest players in the league. Arias was hitless through his first two games at Triple-A, but homered for his first hit on Tuesday. It might be tempting to promote him for the stretch run, but we’ve seen the pressure prospects in Boston face, not to mention the Red Sox are pushing for the postseason and Arias is still very young.One curiosity at this deadline is that league sources have indicated the Red Sox are still pursuing upgrades at shortstop. That was the case even before Mead broke his wrist. The Red Sox view Arias as a future shortstop, but they already have Trevor Story about a month away from returning from sports hernia surgery. That’s not including Marcelo Mayer, also on the injury list with a forearm stress reaction.Story and Mayer haven’t performed well this season, but throwing Arias into the mix adds a ton of pressure. Meanwhile, if Arias is their shortstop of the future, the Red Sox could have considered moving Story to second (Story is under contract through 2027 and owed $25 million next year), but the team just acquired Mead, who’s 25 and will likely be their long-term second baseman. Perhaps Story moves to second when he returns if Mead is still out, but it’s unclear now how long Mead will be sidelined. That also leaves Mayer as the odd man out, though he could be optioned to Triple A once healthy. Trading Story is an option, but finding a suitor might be tough. If the Red Sox do acquire another shortstop it would interfere with Arias’ future, unless they plan to trade him. If they acquire a shortstop and keep Arias, it further boxes out Story.Which prospects/young players are more likely to be traded, and who is seen as untouchable? – Noah SSince we’re on the topic of Arias, it is possible they trade him, though I do view that as highly unlikely. As the No. 4 prospect in baseball per The Athletic’s Keith Law, the Red Sox would likely only consider trading Arias for an All-Star player with several years of control. Rockies catcher Hunter Goodman fits that profile, and the Red Sox have been tied to him, but trading Arias still would be tough.
