Gardner will need some additional help to punch a ticket to Cincinnati and join Dellin Betances and Mark Teixeira at next week's Midsummer Classic, though, as he currently stands as one of the five American League Final Vote candidates.
"Gardy has turned himself into a dynamic all-around player," Yankees manager Joe Girardi said. "He has also evolved into one of the true leaders in our clubhouse. He's a tremendous outfielder and an offensive force who can affect the outcome of a game in so many ways."
Gardner, 31, is batting .297 with a .373 on-base percentage and a .481 slugging percentage in 76 games. His resulting .854 OPS ranks fifth among AL outfielders.
Gardner has scored 60 runs -- good for third in the AL, and tied with Mike Trout for most among AL outfielders -- while legging out 21 doubles and three triples. He's also slugged nine homers and driven in 39 runs while ranking fourth in the AL with 15 stolen bases in 18 attempts.
"I know Yankees fans gravitate toward the way he plays the game, because he plays it with a great deal of grit and determination," Girardi said. "It's my hope that we can all rally behind him and give him the opportunity to play in his first All-Star Game. It's hard not to root for a guy like Gardy."
In addition to serving as a spark plug atop the lineup while Jacoby Ellsbury has been on the disabled list with a knee injury, Gardner has contributed plus defense in both left and center field.

"I hope our fans get behind Brett Gardner in the online final vote," Betances said. "He's a big reason for the success we've had this year, and I believe he should be an All-Star."
