Add The Sporting News as a Preferred Source by clicking here.The San Francisco Giants conducted a sell-off at this year's trade deadline, parting with Tyler Mahle, Luis Arraez, Robbie Ray, Erik Miller, Caleb Kilian, and Heliot Ramos by the end of the MLB trade deadline.All of those moves helped the Giants land some intriguing prospect hauls, but of those four deals, two stood out to one National League executive.According to Jesse Rogers of ESPN, one NL exec called out the Arraez and Ray trades as their "favorite" deals of the deadline, thanks to the pitching prospects the Giants got in those two deals.Giants praised for Luis Arraez, Robbie Ray trade returns"I really liked what the Giants did to get Ramon Marquez and Miguel Mendez in their two deals and build up legitimate starting pitching depth in their system," an NL exec said.This NL executive is a big fan of what the Giants did at the trade deadline, specifically the haul Buster Posey and company were able to get for Arraez and Ray, two rental players.Arraez was sent alongside Caleb Kilian to the Philadelphia Phillies in exchange for Ramon Marquez and Marty Gair, two right-handed pitching prospects.But, of those two, Marquez is by far the most intriguing. He's had a breakout 2026 season in the Phillies' farm system, and while he wasn't a top-100 prospect yet, he easily could jump into that mix during the 2027 season, if not by 2028.MORE:How Cubs inadvertently helped Dodgers trade for Tarik SkubalTheir other trade that this NL exec is a big fan of was the Robbie Ray deal with the NL West rival San Diego Padres. They landed right-handed pitching prospect Miguel Mendez and 17-year-old shortstop prospect Joniel Hernandez.While Hernandez is a very intriguing prospect worth keeping in mind, he's a ways away. Mendez is a lot closer to the big leagues, and he's a good prospect to land in exchange for a rental in Ray.The Giants made some other exciting deals, like the one to acquire Marcelo Mayer from the Boston Red Sox, and the deal with the New York Yankees involving Henry Lalane and Kaeden Kent.But the hauls Posey and the Giants got for Arraez and Ray, the two rentals they were expected to trade all along, were the NL executives' favorite moves of the entire MLB trade deadline.More MLB news:Cubs land Kevin Gausman in blockbuster trade with Blue JaysRed Sox expected to trade Jarren Duran during offseason, not MLB trade deadlineWhat did Mets get for Freddy Peralta?
