Quick Hits: Nationals, Mets, Wandy, Blue Jays

On this date 25 years ago, A's rookie Mark McGwire hit his first MLB home run. Another historic slugger, Jim Thome, could be on the move this week. Here are the latest links from around MLB…

• Thomas Boswell of the Washington Post wants to see Davey Johnson return as the Nationals' skipper in 2012.  Earlier this week, GM Mike Rizzo raved about Johnson's ability to connect with his players.
• The Mets haven't yet had internal discussions about picking up the 2013 option for manager Terry Collins, but they'll likely discuss the possibility within the next month, according to Andy Martino of the New York Daily News. 
• Ken Rosenthal of FOX Sports hears from someone connected to baseball management who wonders why MLB players don't insist on slotting. Capping bonuses does have potential benefits, but as Rosenthal explains, it's far from an ideal system.
• The Astros wanted Wilin Rosario or Drew Pomeranz for Wandy Rodriguez, but the Rockies were only offering Jason Hammel, Casey Weathers or Christian Friedrich, according to Danny Knobler of CBSSports.com (on Twitter). Talks between the two teams reached a standstill yesterday, after the Rockies claimed Rodriguez earlier in the week.
• The Blue Jays announced that they signed non-drafted free agent Luke Willson, a left-handed hitter who also plays tight end for the Rice University Owls.
