SAN FRANCISCO (AP) — Yasiel Puig added a two-run single and Senzel got two hits.
Castillo (4-1) allowed two hits and walked five. Last Sunday, facing the Giants in Cincinnati, the hard-throwing 26-year-old took a no-hitter into the sixth inning and was sitting on four-run lead, then gave up four runs in a game San Francisco won 6-5.
Castillo combined with Zach Duke, Michael Lorenzen and Wandy Peralta on a four-hitter.
The Reds led 1-0 in the second when they put two on with two outs for Senzel. He hit a deep drive off Dereck Rodriguez (3-5) and center fielder Steven Duggar crashed into the wall trying to make what would have been a great catch, but the ball popped out of his glove on impact.
Senzel wound up with a triple and later scored on a double by Eugenio Suarez.
Puig's single came in a three-run ninth.
Rodriguez lost his third straight start. Stephen Vogt had three hits and walk in his sixth game with the Giants and is batting .467 (7 for 15) with his new team.
