During said second half, Martinez managed the game's best slugging percentage (.751), isolated power (.445), home-run rate (11.3 percent of his plate appearances) and wOBA (.472), his 31 home runs trailing only Giancarlo Stanton, thriving in one of the game's most hitting-friendly environments following his mid-season trade to the Diamondbacks. While Martinez's power metrics are destined to naturally regress, as that half-year was historic and practically impossible to repeat, and Fenway Park's Green Monster could convert a handful of his homers into extra-base hits, what he loses in that department he could gain in terms of runs/RBIs/plate appearances by joining a loaded lineup. He's capable of a batting average anywhere from .275-.300, and 30-plus-homer power, assuming he can stay healthy enough to accrue the at-bats to get there. Martinez is well worth an early-round pick."},"mostRecentNews":{"date":"Fri Oct 26","news":"Martinez (ankle) will start in left field and bat cleanup in Game 3 of the World Series against the Dodgers on Friday, Joel Sherman of the New York Post reports.","spin":"There was some concern that Martinez wouldn't be able to take the field Friday night due to an ankle injury, but the 31-year-old didn't have any issues in pre-game drills so he'll be ready to go for Game 3. Since there's no DH in the Dodgers' National League park, Andrew Benintendi will begin Friday's contest on the bench as Martinez patrols left field."},"fullName":"J.D.
