More than 480 million votes have been cast in the previous 13 years of this popular summer pastime. Last year was an all-Chicago finish, as Cubs first baseman Anthony Rizzo won in the NL with 8.8 million votes and White Sox left-hander Chris Sale won in the AL with 6.7 million.
Here is a closer look at this year's choices:
Johnny Cueto: How about your best outing of the year during Final Vote week? Cueto dominated the Nationals to improve to 6-5, his second straight strong start. Will he get another big hand at GABP? And will he make it 2-for-2 for Cincinnati, which won this vote with Joey Votto in 2010? To cast your mobile vote for Cueto, text N1 to 89269.

Jeurys Familia: He started the on-field campaigning by converting his 23rd save on Monday and lowering his ERA to 1.13. Familia has thrived in his first season as a closer, saving 23 games in 25 chances. To cast your mobile vote for Familia, text N2 to 89269.

Clayton Kershaw: The three-time Cy Young Award winner, whose next start comes Wednesday at home against Philadelphia, is on pace to surpass his personal season-high strikeout total of 248. Kershaw (5-6, 3.08 ERA) also was among league leaders in innings pitched (114, third), opponents' batting average (.216, eighth) and WHIP (1.04, eighth). He is trying to become the Dodgers' second Final Vote winner after Nomar Garciaparra won it in 2006. To cast your mobile vote for Kershaw, text N3 to 89269.

Carlos Martinez: Cardinals fans turned out big to win this for David Freese just three years ago, and now they'll be asked to do the same for the "Tsunami." Martinez will go after his 10th win on Thursday, which means you probably have all the voting evidence you need, including a 1.52 ERA in his last 10 outings and nine straight quality starts. To cast your mobile vote for Martinez, text N4 to 89269.

Troy Tulowitzki: The four-time All-Star extended his hitting streak to 19 games and his on-base streak to 34 with his RBI single on Tuesday. He started the season slowly, which explains why the top NL vote-getter of 2014 dropped in the starter balloting this time. Colorado just missed its first Final Vote winner last year, when Justin Morneau was passed by Rizzo down the stretch. To cast your mobile vote for Tulowitzki, text N5 to 89269.

Xander Bogaerts: He leads AL shortstops with 91 hits, and he has hit safely in 29 of his last 34, playing the hero in Tuesday's win at Fenway. Bogaerts became the first Red Sox player with a three-run single in the regular season since Gary Allenson against Detroit on Sept. 11, 1982. The Red Sox have won the Final Vote three times, tied with Philadelphia for second all time behind the White Sox (four). Previous winners were Hideki Okajima in 2007, Jason Varitek in '03 and Johnny Damon in '02. To cast your mobile vote for Bogaerts, text A1 to 89269.

Yoenis Cespedes: The defending two-time Home Run Derby champion, in his first year with Detroit, entered Tuesday with 94 hits, and only selected All-Stars rank above him on that list. Cespedes started this voting period by launching a tape-measure homer to start a big comeback to beat Seattle, then hit a game-tying shot in Tuesday's loss. Detroit is 1-for-6 in previous Final Votes, with third baseman Brandon Inge winning it in 2009. To cast your mobile vote for Cespedes, text A2 to 89269.

Brian Dozier: The bulldozer outside Target Field told the story on Tuesday. His walk-off homer on the night he appeared on the ballot marked Dozier's 17th long ball of the season, and 14 of those have come in the leadoff spot. Dozier entered Tuesday tied with Blue Jays third baseman Josh Donaldson for the Major League lead in runs scored (63), and TBS analysts Cal Ripken Jr. and Pedro Martinez both said Tuesday he is their Final Vote choice. Dozier will try to become Minnesota's first successful Final Vote candidate in six tries. To cast your mobile vote for Dozier, text A3 to 89269.

Brett Gardner: The Yankees' center fielder walked, singled and scored a run in a losing cause against Oakland on Tuesday. He is right behind Dozier with 61 runs (tied for third in the Majors), but he has a higher average at .296 and has swiped 15 bases. Two Yankees outfielders have won the Final Vote: Nick Swisher in 2010 and Hideki Matsui in '04. Yankees fans will note that Swisher beat a Boston rival (Kevin Youkilis) that year, so there's another rivalry vote happening this time with Bogaerts. To cast your mobile vote for Gardner, text A4 to 89269.

Mike Moustakas: You don't have to go far back to find proof that "Moose" can find votes; he led in the fan balloting at AL third base for much of the campaign. Moustakas' slash line entering this week for the AL Central leaders was .301/.357/.436. He was on bereavement leave and missed Kansas City's game on Tuesday. To cast your mobile vote for Moustakas, text A5 to 89269.
