The 30-year-old will look to continue with his hot bat, as he's 13-for-24 with three doubles, two home runs and five RBI over his last six games.","date":"Sat Apr 21"},"fullName":"J.D. Martinez","seasonOutlook":{"outlook":"Inexplicably, after putting forth one of the most productive second halves of 2017 of any player in baseball, Martinez lingered on the free-agent market deep into February, before finally signing with the Red Sox. 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.","seasonId":2018,"date":"Tue Feb 20"},"playerRater30DAY":6.1,"playerRater15DAY":8.9,"positionRank":11}
