Team could really use his extending the lineup even if only a tad below league-average OPS+ and RBat like last season. This year he's 35+ below in both categories... last year just 5. Diaz will probably help Vasquez's production just by allowing Christian more rest. Vasquez started strong, then faded with more games likely due to fatigue. Teng is holding Vasquez's beer, but Christian is still drunk too. Yainer faded in September the past two seasons but it's hard to pinpoint anything with him besides streaky and free-swinger. Maybe Vasquez will help Diaz by lightening his load too if fatigue was an issue.
