Arenado dueling Carter for NL home run title, while Trumbo leads in AL
By William Boor
With multiple teams still fighting for playoff spots and others trying to clinch home-field advantage, there's plenty to watch on the final day of baseball's regular season.
However, the playoff chase isn't the only thing worth monitoring. There are also several players vying for spots on the league leaderboard, perhaps hoping to leave one final impression on those voting for postseason awards.
Jose Altuve is in line to win his third consecutive Silver Slugger award and leads the American League with a .338 average. Mookie Betts (.320) won't be able to match Altuve's average, but has a chance to lead the league in hits for the first time in his career.
Altuve enters the season's final day with 215 hits, while Betts has 214.
In the National League, Jean Segura's 203 hits are 10 more than his closest competitor, but when it comes to batting average, the race is tight.
Daniel Murphy is hitting .347, while DJ LeMahieu's average sits at .348. Those averages represent career highs for both players and neither has ever led the league in hitting.
Nolan Arenado is set to lead the NL in RBIs for the second consecutive season and may lead the NL in homers for the second time in as many years, as well. Arenado's 133 RBIs give him a 25 RBI lead over Matt Kemp, but the third baseman enters the day tied with Chris Carter at 41 homers each.
In the AL, Mark Trumbo's 47 homers give him a pretty solid lead over Nelson Cruz (43), but the RBI title is still up for grabs.
David Ortiz and Edwin Encarnacion each have 127 RBIs. That's a career high for Encarnacion, who has never led the league in RBIs. Meanwhile, Ortiz has eclipsed 130 RBIs twice in his career, both times leading the league.
Rick Porcello's 22 wins mark a career high and will be the best mark in all of baseball. Max Scherzer has an opportunity to win 20 games for the second time in his career if he's able to top the Marlins and in doing so, he'd lead the NL in wins. If not, he will finish tied with Jon Lester at 19 wins.
Kyle Hendricks gets the ball on the final day of the regular season as the Cubs face the Reds, but his ERA title appears to be safe. Hendricks has a 1.99 ERA through 30 games, while Lester sits in second place with a 2.44 ERA.
In the AL, Aaron Sanchez will have to put together a quality start if he wants to win the ERA crown. The Blue Jays' right-hander has a 3.06 ERA, narrowly edging out New York's Masahiro Tanaka and his 3.07 ERA.
Justin Verlander, who led the league with a 2.40 ERA in 2011, is also in the mix with a 3.10 ERA entering his final start.
Mike Trout, who has 29 homers and 29 stolen bases, has a chance to become the first player in baseball to notch a 30-home run, 30-steal season since 2012, when both he and Ryan Braun did so.
