9. Freddy Sanchez plays a key role in 2010 World Series title
Date: July 29, 2009
To Giants: 2B Freddy Sanchez
To Pirates: RHP Tim Alderson
A three-time MLB All-Star and the NL batting title winner in 2006 when he hit .344, Freddy Sanchez joined the Giants with an impressive track record of offensive success.
He hit just .284/.295/.324 in 25 games after the trade, but that didn’t stop the Giants from signing him to a two-year, $11 million extension that replaced a club option for 2010.
The 32-year-old responded by hitting .292/.342/.397 for a 102 OPS+ and 1.9 WAR in 111 games in 2010.
After a 2-for-16 performance in the NLDS, he went 14-for-47 (.298) with four doubles and three RBI in the NLCS and World Series combined.
Injuries took a toll from there and he played just 60 games the following season in what ended up being his final MLB action.
However, his role on a World Series winner is enough to earn him a spot inside the top 10 in these rankings.
The player heading the other way in the deal, Tim Alderson, was the No. 4 prospect in the San Francisco farm system and the No. 45 prospect in baseball at the start of 2009, according to Baseball America. He never reached the majors, though, topping out in Triple-A.
