SAN FRANCISCO No matter what else happens in his career, Ty Blach will always be the subject of a good trivia question.Who started on Opening Day for the San Francisco Giants in 2018?It was not Madison Bumgarner, the franchises ace. It was not Johnny Cueto, who looked like a Cy Young candidate before his elbow started aching, or Jeff Samardzija, who was coming off a strong year. It was not Derek Holland, the former top prospect, or youngsters Dereck Rodriguez or Andrew Suarez, who may look back at 2018 as the year long big league careers started.
