Cano is currently at 726,158 votes, with Kinsler at 649,926. Dustin Pedroia of the Red Sox is third with 540,515, while the Twins' Brian Dozier sits fourth among second basemen with 360,089.
Cano has a chance to become the third second baseman in AL history to earn five consecutive fan-elected starts, joining Hall of Famers Rod Carew (six straight from 1970-75) and Roberto Alomar (five straight, 1996-2000).
In addition, Cano would join Bret Boone (2001) as the only fan-elected starting second basemen in Mariners history, and he could become just the fourth Seattle infielder to receive an election from the fans, joining Boone, first baseman John Olerud (2001) and shortstop Alex Rodriguez (1997-98; 2000).
The Mariners haven't had any position players selected to the All-Star team since outfielder Ichiro Suzuki in 2010.
Cano has been sidelined the last four games with a bruised left hand, which already is the most games he's missed in a season since 2007. The Mariners are in New York on Monday night for a makeup game against the Yankees, which will be Cano's third game back in the Bronx since signing a 10-year, $240 million deal with Seattle.
Heading into Monday's game, the 31-year-old Cano ranks third among AL hitters with a .327 batting average, is tied for third with 22 multihit games and is tied for seventh with 67 hits.
Cano is the only Mariners player ranked among the top five position players or top 15 outfielders in the AL All-Star voting. The updated National League numbers will be released on Tuesday.
The other change among AL leaders from the first week comes at designated hitter, where the Orioles' Nelson Cruz has overtaken Boston's David Ortiz.
