ST. PETERSBURG -- Grady Sizemore is a power hitter batting leadoff, and now he has the club record to prove it.

When Sizemore belted Rays left-hander Scott Kazmir's 2-0 fastball over the right-field wall at Tropicana Field, he notched his 19th career leadoff homer, breaking the club record set by Kenny Lofton.

Unfortunately for Sizemore and the Indians, the game will be remembered more for the homer that ended it -- B.J. Upton's walk-off blast off Luis Vizcaino to give the Rays an 8-7 win -- than the one that began it.

But Sizemore still had to acknowledge his achievement.

"I guess it's exciting," Sizemore said. "Obviously this wasn't the way we wanted to end the game, so that's all I'm thinking about now. It's not a stat you focus too much on, but it's cool to have. Hopefully I can continue to have that success and set the bar high."

Sizemore, who notched 30 homers and 30 stolen bases last season, hasn't reached his usual level of success this year. He's batting .226 with seven homers and 25 RBIs. Manager Eric Wedge said earlier this week that he might consider moving Sizemore down in the order.
