San Francisco Giants: 15 greatest MLB trade deadline deals of all time

11. Workhorse Livan Hernandez earns a four-year extension

Date: July 25, 1999
To Giants: RHP Livan Hernandez
To Marlins: RHP Jason Grilli, RHP Nate Bump

The Giants paid a steep price to acquire Livan Hernandez from the then-Florida Marlins at the 1999 trade deadline.

Jason Grilli was the No. 1 prospect in their system and the No. 44 prospect in baseball at the time, according to Baseball America, while Nate Bump had been the team’s first-round pick in 1998 and checked in as the No. 4 prospect in the system.

The 1997 NLCS and World Series MVP, Hernandez went 3-3 with a 4.38 ERA in 10 starts after the trade, but the Giants missed the postseason.

He signed a four-year, $11.1 million extension during the offseason and spent three more seasons in San Francisco, winning 42 games while posting a 4.44 ERA and averaging 228 innings per year.

Hernandez turned in quality starts in the 2001 NLDS (8.1 IP, 3 ER) and NLCS (6.1 IP, 2 ER) to help the Giants reach the World Series, but he allowed a combined nine earned runs in 5.2 innings during his two starts in the Fall Classic.

Prior to the 2003 MLB season, he was traded to the then-Montreal Expos in exchange for reliever Jim Brower, who went on to lead the NL with 89 appearances in 2004.
