Jason Grilli will be returning to the Pittsburgh Pirates with a two-year deal, Ken Rosenthal reports.

Grilli, aka Gary Sheffield’s client, reinvented himself as a late innings reliever over the last two seasons with the Pirates. The 36-year old posted a career high in strikeouts in 2012 with 90, while walking just 9% of the 244 batters he faced. Grilli missed all of the 2010 season with a knee injury, but signed a minor league deal with the Phillies in 2011. He joined the Pirates on another minor league contract in July of 2011. He posted a career best 2.48 ERA in 32.2 innings of work in his first year with the Bucs.

Bob Nightengale of USA Today notes on Twitter that Grilli turned down more money from other suitors to return to Pittsburgh.

Girlli finished 2012 with 58.2 innings pitched, a 2.91 ERA, 2.80 FIP, 2.68 xFIP, and 13.81 K/9. His 30.7% ground ball rate was the lowest mark of his career, although, his average fastball velocity was up over 93 mph for the first time since the 2007 season. Grilli’s deal is pending a physical, financial terms were not immediately available.
