Vladimir Guerrero showing resurgence?

Vladimir Guerrero hit a three-run homer on Sunday to give the Rangers a 6-1 lead at the time. They hung on for a 6-3 win.

Guerrero, who hit just .210 in July and struggled early in August, has a 10-game hitting streak. He's batting .317 in that span and had four RBI in the past two games. No, the RBI haven't been what they were early in the season -- 5 total in those 10 games. But he's swinging the bat again and that's a good sign.

The home run ended a long drought for Guerrero. In fact, he's had some large breaks between his last few homers. Here are some numbers from ESPN Stats & Information:

Guerrero hit homer No. 20 on July 9 then went 16 games without a homer. He hit No. 21 on July 31 (his first in 17 games) then went 17 games without a homer until Sunday (his first in his 18 games).

The last time he went 17 games without a homer was last season:

He hit his first homer on April 12 then went 28 games without a homer (hit No. 2 on June 25 ... he DNP April 16-May 24).

Is this a sign Guerrero is coming around?
