Brian Wilson likely to sign soon

Free agent reliever Brian Wilson is expected to sign soon and has received offers from four National League teams and one American League team, according to Bob Nightengale of USA Today. ESPN's Jim Bowden notes that the Giants, Pirates and Dodgers are the frontrunners to sign the right-hander, who is recovering from his second Tommy John surgery.

While there were three actual trades going down on Monday, there was a lot going on behind the scenes. Here's a quick recap of everything you need to know before the trade deadline.

CBSSports.com's Scott Miller notes that the Diamondbacks also have some interest in Wilson, and says that 31-year old is in the process of exchanging offers and counter-offers with teams at this time.

After aggregating all of the reports, it seems as though the four National League teams with offers out to Wilson are the Pirates, Giants, Dodgers and Diamondbacks.

The one American League team is either the Athletics or Rangers, who were the only AL teams to watch his audition in Los Angeles on Thursday.

The Phillies, Rockies and Cardinals were also in attendance, but have apparently decided against the idea of taking a flyer on the 3-time All-Star.

While the familiarity with the Giants may factor into Wilson's decision, he has also been known for his desire into Los Angeles, which would make the Dodgers an obvious fit. The Pirates, who recently lost All-Star closer Jason Grilli to injury, are looking for bullpen help and are known to be strong in their pursuit of Wilson.

Wilson only appeared in two games in 2012 before being shut down due to injury, and was non-tendered by the Giants after the season. In even with San Francisco, Wilson has posted a 20-20 record with a 3.21 ERA and 171 career saves. He was a key member of the Giants' championship team in 2010, posting a 1.81 ERA and 48 saves in 70 appearances on the season.
