Right-hander Pedro Martinez, who last pitched in the Majors in 2009, said he will soon officially announce his retirement, according to Cash Kruth of MLB.com.

Martinez had apparently remained open to a return to the bigs since appearing in nine regular-season and two postseason games with the Phillies in '09, but nothing materialized, and now at age 40 and two full years removed from big league action, it's hard to imagine him catching on anywhere.

A three-time Cy Young Award winner and arguably the best pitcher of the offense-heavy 1990s and early aughts, Martinez has already cemented his legacy as one of the top hurlers in MLB history and projects as a lock for the Hall of Fame.

Martinez will hang 'em up with a record of 219-100 and a 2.93 ERA in 18 seasons with the Dodgers, Expos, Red Sox, Mets and Phillies. The advanced metrics are equally flattering as the traditional stats: 154 ERA+, 2.91 FIP, 89.4 WAR. Pedro's 291 ERA+ in 2000 is the highest single-season adjusted ERA in the modern era.
