Morneau is currently leading all NL players with a .317 batting average, and he's clubbed 14 home runs in 112 games for Colorado. The Brewers are playing veterans Mark Reynolds and Lyle Overbay at first base.
Morneau, a four-time All-Star and the 2006 AL Most Valuable Player, has regained his form after a few seasons affected by concussions. The veteran has played in the playoffs in three seasons, twice with Minnesota and last year with the Pirates after being acquired in August.
Morneau, 33, signed a two-year contract with the Rockies last December that includes a mutual option for 2016. Morneau has batted .310 with a .345 on-base percentage and a .500 slugging mark at Coors Field and .325 with a .376 on-base and .500 slugging on the road.
