Long answer - REALLY REALLY bad.
It's comforting to know that the Giants are now GUARANTEED a loss every fifth game. Over the past few years, Ortiz stunk up every game he even walked by. In Dec 2004, Ortiz signed a four-year, $33 million contract with Arizona. ($22 Million of which he got paid not to play... nice work if you can get it!)
It wasn't always quite so bad. For four games in April 2005, Ortiz made the Diamonbacks look only a little foolish with a 2-1 record. Then, on May 2, 2005, the fit hit the shan!. Still reeling from that weekend's midling box office returns of A Hitchiker's Guide to the Galaxy, Russ Ortiz put up three sevens (hits, runs, and ER). Things got only worse from there. Since May '05, Ortiz has started 28 Games with a record of 3-18! The Diamondbacks got a hard lesson on the price of winning, spending $6.6 Million per victory on Ortiz. Let's just hope the Giants get a similar return on investment.
