SAN DIEGO (AP) — Randy Arozarena homered again at Petco Park and Mike Zunino drove in the go-ahead run for the Tampa Bay Rays, who beat the Houston Astros 2-1 in the opener of the AL Championship Series. Blake Snell allowed José Altuve’s homer as he labored through the first inning on 29 pitches before the 2018 AL Cy Young Award winner settled down to pitch five innings for the win. Diego Castillo got the last five outs for the save. He came on with the bases-loaded with one out in the eighth and got out of it with one pitch when Yuli Gurriel grounded into a double play.
