Passan reports that the deal is for five years and $90 million, plus a $15.4 million posting fee for the Orix Buffaloes, making it the richest deal for a Japanese position player.
Yoshida, 29, is a left-handed bat who led Nippon Professional Baseball in OPS each of the last two seasons. Last year, he hit .335 with 21 home runs, 88 RBIs and a 1.008 OPS in 119 games. He struck out just 41 times in 508 plate appearances. Passan points out that only Luis Arraez had a lower strikeout rate in MLB last season.
Yoshida, who is listed at 5-foot-8 and 176 pounds, fills an obvious hole for the Red Sox in the outfield and could hit at or near the top of the lineup.
