PHILADELPHIA (Interstat) — The Arizona Diamondbacks and Philadelphia Phillies will decide their three-game series with a Sunday afternoon finale at Citizens Bank Park on April 12. First pitch is scheduled for 1:35 p.m. EDT under clear skies with a game-time temperature of 63 degrees. The series is tied after a pair of tight contests. The Diamondbacks (8-7) won 5-4 on Friday before the Phillies (7-7) evened it with a 4-3 victory Saturday. Arizona will send right-hander Zac Gallen (1-1) to the mound. Philadelphia counters with right-hander Andrew Painter (1-0). Both pitchers are coming off strong outings. Gallen allowed two runs over six innings in a no-decision against Atlanta on April 5. Painter earned the win Saturday against Arizona, allowing two runs over five innings with six strikeouts. A player to watch for the Diamondbacks is right-hander Brandon Pfaadt, who took the loss Saturday despite a quality start, allowing three runs over six innings with six strikeouts. For the Phillies, a key will be the performance of starter Taijuan Walker, who earned the win in Saturday’s game. In Saturday’s Phillies victory, Kyle Schwarber provided the decisive blow with a three-run home run. Arizona’s Ketel Marte also homered in the loss. According to National Statistical’s game simulator, the projected final score is Diamondbacks 6, Phillies 5. Following the game, the Diamondbacks travel to Baltimore for a three-game set starting Monday. The Phillies will remain home to begin a series against the Chicago Cubs on Monday.
