Astros: Robinson Chirinos and the Astros have finalized a $5.75 million, oneyear contract, giving catching-thin Houston another option behind the plate. The 34-year-old spent the past six seasons with the Texas Rangers and hit .222 this year while setting career bests with 18 homers and 65 RBIs in 113 games. His .757 OPS was second among AL catchers. Cubs: Closer Brandon Morrow likely will miss the start of the season following arthroscopic surgery on his right elbow last month. Chicago president of baseball operations Theo Epstein revealed Thursday that Morrow’s operation took place on Nov. 6. The Cubs waited to make an announcement because Morrow’s recovery will impact how they fill out the bullpen.
