Cardinals' Luken Baker: Gets first big-league promotion

The Cardinals selected Baker's contract from Triple-A Memphis on Sunday. He'll serve as St. Louis' designated hitter and No. 7 batter in his MLB debut in the Cardinals' series finale versus the Pirates and left-hander Rich Hill.

The 26-year-old earned his first big-league call-up after slashing .313/.434/.641 with 29 extra-base hits (18 home runs, 11 doubles) to go with an impressive 17.8 percent walk rate and 21.7 percent strikeout rate over 244 plate appearances with Memphis. Though his bat certainly looks big-league ready, Baker's lack of defensive flexibility may hurt his chances of earning a permanent role with the Cardinals. He's played only at first base in the minors, and with reigning National League MVP Paul Goldschmidt already entrenched at that position, Baker's path to playing time will likely come solely at designated hitter. Baker is further hurt by the fact that he's a right-handed hitter, potentially relegating him to the short side of a platoon.
