Phillies' Taijuan Walker to make season debut vs. struggling Padres

The veteran right-hander gets his first start of the year Sunday for the Philadelphia Phillies as they try to complete a road sweep of the San Diego Padres. Walker joins a rotation that has been as good as any in baseball during the season's first month. Aaron Nola and Ranger Suarez have keyed 9-3 and 5-1 wins in the series' first two games with eight-inning outings, continuing a trend that has helped Philadelphia start 18-10 and post a National League-low staff earned run average of 3.26.
