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":"Sun Sep 23","news":"Martinez is out of the lineup Sunday against the Indians, Pete Abraham of The Boston Globe reports.","spin":"Martinez will rest for the second Sunday in a row with the Red Sox having already secured their spot in the postseason and well on their way to clinching the best record in baseball. The slugger will most likely get another day off or two during the final week of the regular season, but it will be tough for fantasy owners to justify benching a player slashing .332/.415/.588 in the second half."},"fullName":"J.D.
