Christian Yelich spent September in pursuit of the National League Triple Crown, putting together numbers that have propelled him into the frontrunner seat for the NL MVP Award. In the American League, Michael Trout was named Angels MVP by his peers and put the stamp on another stellar season.

For their efforts, Trout and Yelich were named the AL and NL Players of the Month, respectively, for September.

Heading into Monday, Yelich led all NL hitters with a .352/.500/.807 slash line over 26 games, clubbing 10 homers, which tied Trevor Story and Luke Voit for the MLB high. The Brewers right fielder fell short of becoming the NL's first Triple Crown winner since the Cardinals' Joe Medwick in 1937.

A change of scenery and a postseason push have propelled Yelich to a career year. When he was acquired by the Brewers in January, the fit seemed perfect. Yelich brought a strong but perhaps untapped swing to a ballpark that is known to be more beneficial to hitters, while leaving the spacious confines of Marlins Park. Yelich was an All-Star for the first time, and Monday's honor was a first for the 26-year-old as well.

Trout hit .329/.469/.684 with eight homers and 16 RBIs over 24 games in September to cap another MVP-caliber season. Trout's 1.153 OPS for the month ranked behind only Rays outfielder Tommy Pham (1.180) for the AL lead. Others in consideration for AL Player of the Month honors were Red Sox right fielder Mookie Betts, Astros infielder Yuli Gurriel and Pham. This marked the fifth time Trout received the monthly honor.
