In the American League, the honor went to Tigers first baseman Miguel Cabrera, who was to participate in the Home Run Derby and start at first for the AL in place of the injured Justin Morneau. Cabrera led the American League with a .435 average (10-for-23) and .913 slugging percentage for the week. He belted two homers and two doubles while driving in eight runs and scoring five more.
In driving in a run on Sunday against the Twins, it gave him at least one RBI in each of his last eight games against Minnesota. He joined Albert Pujols (eight against the Brewers) as the only Major Leaguer with an RBI in at least eight straight games against single opponent this season.
The National League winner, Buster Posey, is in his rookie season, but he certainly hasn't been swinging the bat like a newcomer. The 23-year-old hit .556 (15-for-27) for the week, tops in the Majors. He also led MLB with 14 RBIs over his seven games, along with on-base percentage (.594), slugging (1.222), total bases (33) and hits.
He hit five homers for the week, tying for first in the NL and his nine runs scored placed him second in the circuit. He had four this and six RBIs in one game in Milwaukee, a contest that saw him record his first mulit-homer game and his first grand slam. He had one other four-hit game during the week, with a home run and three RBIs against the Nationals. Posey is among the rookie leaders in average, home runs, RBI, on-base percentage and slugging percentage, even though he didn't get called up until the end of May.
