This series has been of some note because the Twins' starting second baseman is now Alexi Casilla, he of J.C. Romero-trade fame.

Casilla was the Twins' 2006 organizational player of the year, having batted .318 with 84 runs, 22 doubles, 7 triples, 46 RBI, and 50 stolen bases in 123 games between Class A and AA.

I wouldn't expect him to hit for much of an average just yet -- he's only 23 and hasn't spent much time in the Majors, or even in Class AAA -- but with his speed, defense and solid contact skills, he seems likely to hit in the high .200s or low .300s once he settles in.

Of course, while Romero was nothing short of a bust, the Angels are so loaded with middle infielders that Casilla's value to the Angels would be much less than it would be for most clubs. So Angels fans can take some solace in that.
