HOUSTON (AP) -- Bartolo Colon struck out a season-high nine in seven scoreless innings, and the Oakland Athletics completed a sweep of the Houston Astros with a 6-2 win Sunday.

Dating to 2007, Oakland has won 11 straight against Houston, tied for the third longest winning streak against one team in A’s history.
Colon (5-2) won his second straight start, scattering nine hits a day after turning 40. He worked seven innings for the second straight start and for the fourth time in 10 starts this season.

Yoenis Cespedes led off by reaching second base on an error by second baseman Jose Altuve that allowed. Josh Donaldson followed with an RBI single up the middle. After Jed Lowrie singled, Seth Smith had a run-scoring double and Freiman made it 4-0 with another double. Crisp added a two-out RBI single.
Freiman made it 6-0 with a home run to center field with one out in the in sixth.
J.D. Martinez had a one-out double off reliever Ryan Cook in the eighth and Chris Carter hit a sacrifice fly to cut it to 6-2 but that was all Houston would get.
Keuchel went six innings, giving up six runs—four earned—and a season-high nine hits. He struck out four.
Jason Castro had a career-high four hits and went 10 for 12 in the series for Houston. Castro became the first Astros player since Ty Wigginton in 2008 to have three consecutive games of at least three hits.
