As Final Votes pour in, players make their cases

As Final Votes pour in, players make their cases

Giants first baseman Brandon Belt temporarily lost his Day 1 lead Wednesday night, but he regained it, as he and Blue Jays outfielder and Canada native Michael Saunders continue to lead their respective league entering the second full day of balloting Thursday in the Esurance MLB All-Star Game Final Vote, held exclusively on MLB.com and the individual club sites.

Cast your Esurance Final Vote

Balloting continues in the Esurance MLB All-Star Game Final Vote, which allows fans to vote in one additional player to each league's All-Star Game roster through 4 p.m. ET on Friday.

While Pittsburgh's Starling Marte took the National League lead briefly several times, Belt has moved back into first place with a total of 4.6 million votes. Marte and Rockies rookie shortstop Trevor Story currently are in second and third, respectively, and only a few percentage points from taking the lead away from Belt. Creative campaigns supporting Jake Lamb of the D-backs and Ryan Braun of the Brewers have helped them make Day 2 pushes, just behind the top three spots.

Saunders has received 9.7 million votes in the American League race and continues to hold off the other four candidates in close races that have the players who are chasing him continuing to jockey for position. Ian Kinsler of the Tigers and Dustin Pedroia of the Red Sox swapped the third and fourth positions multiple times overnight with the Boston second baseman currently holding third behind Saunders' closest competitor, George Springer of the Astros. Kinsler looms close in fourth, ahead of Rays third baseman Evan Longoria.

Latest Final Vote update reveals intriguing trends

Belt was 2-for-4 with two extra-base hits (a double and triple), two runs scored and an RBI in San Francisco's 5-1 win over the Rockies on Wednesday. Marte's Pirates won their seventh straight game Wednesday, vaulting past the Cardinals, 7-5, to claim second place in the NL Central.

Saunders backed up his votes with his bat in a big way on Wednesday, homering and driving in the go-ahead run for the Blue Jays in the eighth inning against the Royals, securing a 4-2 win.

Gibbons campaigns for Saunders

"First and foremost, what's important right now is that we get the wins and finish strong leading into the All-Star break," Saunders said. "Obviously the support that I've received, not only from the guys in the locker room and this organization, but fans all across Canada, words can't explain how grateful I am."

Springer also made some noise Wednesday, contributing at the plate as Houston completed a sweep of the Mariners with a 9-8 victory. Springer pushed his team-leading walk total to 46 and collected his 51st RBI, good for second on the club.

Lamb also made a statement Wednesday, hitting a two-run homer for the D-backs. As did Kinsler, who totaled three hits and three runs scored as his Tigers bested the division-rival Indians, 12-2. Kinsler's teammate, All-Star first baseman Miguel Cabrera, lobbied for his inclusion.

"We have to make a push," Cabrera said. "Kinsler, I think, is our best player in the lineup. He does everything to win games for us."

Kinsler a Final Vote candidate

For Braun, Belt, Lamb and Pedroia, their All-Star fates are firmly in the hands of the fans. With their clubs off on Thursday, they won't have another opportunity to show they belong before voting ends Friday.

Saunders and Kinsler will go head-to-head Thursday as their clubs meet at Rogers Centre, where Saunders can potentially celebrate along with a home crowd after the results are announced during a Final Vote-themed telecast of "MLB Now" on MLB Network and MLB.com on Friday from 4-5 p.m. ET.

Marte, Springer and Story will each also have the opportunity to celebrate at their home ballparks. Marte and the Bucs have one more matchup with the Cardinals in St. Louis before returning home for a three-game series against the first-place Cubs. Springer's Astros host the A's for a four-game series, while Story's Rockies take on the Phillies at Coors Field through the weekend.

If Longoria claims the final AL spot, he'll have to wait to be cheered on by the Tampa Bay fans as the Rays will be in Boston for a brief road trip this weekend when the results are revealed.
