Nick Cafardo of the Boston Globe has lots of hot stove information to share in his latest Sunday Notes column…

• Kendrys Morales has already become a positive clubhouse figure in his short time with the Twins and Cafardo wouldn’t be surprised to see Minnesota try to extend the slugger.  It’s also possible the Twins could deal Morales before the deadline and then re-sign him as a free agent this winter.
• The Diamondbacks seem willing to listen about trade offers for any player except Paul Goldschmidt, Cafardo notes.  Martin Prado could be an attractive trade chip, though possible trade candidates like Bronson Arroyo and Mark Trumbo might not have enough time before the deadline to show that they’re healthy.  “We’re meeting on it.  Figures we are sellers, not buyers,” D’Backs chief baseball officer Tony La Russa said.
• The Red Sox “spent significant time watching Matt Kemp last week,” though Dodgers GM Ned Colletti told Cafardo that Kemp isn’t being traded.  Kemp’s recent hot streak has “reinforced” his value to Colletti given the dearth of right-handed power options around the game.
• The Nationals could make Danny Espinosa available to second base-needy teams like the Giants or Blue Jays once Bryce Harper returns from the DL.  With Harper back in the outfield, Washington would use Ryan Zimmerman at third and Anthony Rendon at second, leaving Espinosa without a regular job.  Given Zimmerman’s shoulder problems and questionable future as a third baseman, however, I’d tend to think that the Nats would keep Espinosa as a valuable depth piece.
• Phillies outfielders Marlon Byrd and Ben Revere appear to be available, as Cafardo adds them to the long list of notable Philadelphia players who could be trade targets before the deadline.
• Red Sox catching prospect Christian Vazquez would be the top ask for any team looking to make a major trade with Boston.  “That would be across the board, even for a major hitter. He’s major league-ready right now offensively and defensively,” a scout tells Cafardo.  “We also think he’ll hit for some power in the majors. Because they have Blake Swihart, who a lot of teams will ask for as well, they probably would reluctantly give up Vazquez.”  This same scout, however, says that between the two young catchers, he would keep Swihart.
• While Nate Schierholtz has only hit .207/.261/.313 in 249 PA this season, the Cubs will likely still trade the outfielder.  Schierholtz is only signed through the end of the season and he is owed approximately $2.78MM in remaining salary.
• The Padres “would like to conduct a fire sale” and Chris Denorfia, Chase Headley, Carlos Quentin and Seth Smith could all be available.  Cafardo notes that Smith would be a good fit in the Red Sox outfield.
• Several teams are interested in Grady Sizemore, who one scout feels will perform better now that he has had time to get re-accustomed to playing.  “Whoever gets him next will probably get a better player than what Boston had. He needed more time, and with that problem offensively up there they [the Red Sox] couldn’t wait,” the scout said.
• The Blue Jays, Cubs, Marlins, Phillies and Rangers have been the teams who have been most aggressively scouting the major and minor league rosters of other clubs, Cafardo reports.
