Madison Bumgarner is scheduled to make his 2018 debut 60 games into the season Tuesday when the San Francisco Giants host the Arizona Diamondbacks on the second night of a three-game series. The four-time All-Star had been penciled in to start Opening Day against the Los Angeles Dodgers back in March before taking a line drive off his left (pitching) hand in his final spring training start. The blow broke a bone below his left pinkie, which landed him on the disabled list, from which the Giants plan to reinstate him Tuesday.
