Houston at San Francisco 9:45 ET
Astros over Giants- A pair of young pitchers get the call in the series opener when Astros right-hander Spencer Arrighetti (3-5, 5.79) faces Giants lefty Kyle Harrison (4-3, 4.18). Arrighetti allowed just one run and three hits and three walks in his three innings against the Cardinals. He has issued multiple walks in all 10 of his starts this season, including three in each of the past three outings despite pitching a total of just 14 innings in those games. The Giants won the first two games of their most recent homestand against the Philadelphia Phillies before losing six in a row. Harrison has taken losses in his past two starts, roughed up for a total of eight runs (seven earned) and 20 hits in 11 innings by the Phillies and Diamondbacks.Take HOUSTON!
