Barry Zito has forged two important unions in the past year that have served to change the direction of his life and perhaps his baseball career as well. One was off the field when he married 25-year-old actress Amber Seyer in December, ending his long run as one of the game's most eligible bachelors. The other was when the Giants pitcher met Hector Sanchez last summer and initiated a working relationship that has evolved into the 22-year-old catcher becoming Zito's full-time batterymate. Coincidentally or not, Zito is off to one of the best starts of a 13-year career that has been mostly downhill since he came to the Giants in 2007. His first four starts have produced a 1.67 ERA, and opposing hitters have a .186 batting average. He is 1-0, having pitched a shutout against the Rockies in Colorado. In short, Zito has become an advertisement for marital bliss.
