This says that the Phillies have agreed to terms with Juan Castro and suggests it may be a one-year deal worth $750,000 with a club option for 2011.

Wow.

Casto turns 38 in June and has a career .601 OPS. He can play short, third and second.

What he can’t do is hit well enough to be allowed on the field. Over the last four season’s he has on-based .281, .211, .246 and .311. He has a career .230 average and a .332 slugging percentage.

He’s a right-handed batter who doesn’t hit either righties or lefties. Last year he played for the Dodgers and hit 287/323/322 against righties, but in 2008 he hit 196/228/271 against righties for the Reds and Orioles.

Here’s how Castro’s career rates for getting hits, walks, doubles and triples, home runs and extra-base hits per 100 plate appearances compare to Bruntlett’s:

  H/100 BB/100 2B+3B/100 HR/100 XBH/100
Bruntlett 20.3 8.5 4.7 1.2 5.9
Castro 21.2 5.2 4.9 1.3 6.2

Castro has been a little more likely to get a hit, less likely to walk and a little more likely to deliver and extra-base hit over his career.

Bruntlett doesn’t turn 38 in half a year, though.

That’s a pretty disappointing move by the Phillies. Yes, you have to have a backup shortstop. Maybe he can do something else, I hear you cry? You really, really don’t want him to. It’s a bad use of a roster spot for a team that has had big problems on the bench for a while now.
