Martinez named American League Player of the Week

Tigers outfielder hit .444 with three doubles, four homers in seven games last week

Outfielder J.D. Martinez's unexpected contributions to the Tigers' lineup have been valuable, and he was rewarded for his efforts on Monday by being named the American League Player of the Week.

It's Martinez's first career weekly honor and the first for the Tigers this season. The last time a Detroit player was recognized was when Miguel Cabrera and Austin Jackson shared the award on Aug. 11 of last year.

Martinez last week hit .444 (12-for-27) with three doubles, four homers, 11 RBIs and six runs scored in seven games, leading the Majors in RBIs and slugging percentage (1.000). He was tied for first overall in home runs, extra-base hits (seven) and total bases (27).

Martinez hit his second career grand slam on Monday against the Royals, and his four RBIs tied a career best for the fourth time. The next day, he set a season high with three hits, also in a losing effort.

Martinez went 2-for-4 with a homer on Wednesday, and his back-to-back multihit games were his first of the year. He homered again Thursday and Friday, marking a new career high for three straight games with a home run. Martinez and teammate Torii Hunter are the only Tigers to do so this season.

Martinez is working on a 12-game hitting streak (hitting .404 with six doubles, four homers, 13 RBIs and seven runs in that stretch), and he has already matched his 2013 homer total (seven) in 50 fewer games (36 so far this year, and 86 last year).
