Bad news, good news for ex-MLB superstar Miguel Tejada ...
Bad News -- someone broke into Tejada's Ft. Lauderdale home and jacked thousands of dollars worth of expensive belongings.
Good News -- Cops have arrested the suspect and Tejada should get his stuff back.
Here's what we know ... Tejada had been spending a TON of time in the Dominican Republic, as he's relocating his family.
Officials says a 60-year-old man who was house-sitting next door noticed that no one was checking in on Tejada's home and saw an opportunity to jack all the fancy stuff that was still inside.
