We don't know if Yunel Escobar is a solution or a problem.

We don't know if he has found a home or the Rays have lost their senses.

Anyway, meet the new shortstop.

Is Escobar, acquired by trade with Miami, the man to energize the Rays infield? Or is he that that other guy _ the fool who late last season heartily earned a three-game suspension and a ticket out of Toronto for scribbling a homophobic slur in Spanish on his eye black for a Blue Jays game?

The Rays might get a steal, a game changer: big and rangy, a slick, flashy glove, a career .282 batter. Escobar has 720 hits as a shortstop since 2008. Only Derek Jeter and Jose Reyes have more.

The Rays might get a headache: someone who after last season was traded twice in two weeks, who makes great plays, then brain cramps on an occasional easy one, or sometimes doesn't run hard, who has played for Atlanta and Toronto, and when he left, as a piping hot potato, there wasn't exactly universal weeping in the clubhouses.

"I'm happy to be here," Escobar said as Rays reliever Joel Peralta translated. "I'm really comfortable. A lot of guys have made me feel that way. I'm going to play and work hard. I'm going to be the best teammate I can. A lot of people have misjudged me, think bad things about me, but I'm going to be here and try to win games."

He's 30, and if he can't make a fresh start under Joe Maddon, he might not get many more chances.
