OAKLAND (AP) — Oakland Athletics middle reliever Liam Hendriks pumped his fist and did a little spin as he came off the mound after striking out Baltimore Orioles slugger Mark Trumbo to end the seventh inning.Ryan Madson wasn’t as demonstrative but was equally pumped up after getting Chris Davis to strike out looking to end the game with the tying run on first base.Manager Bob Melvin’s ballclub might have the third-worst record in the AL but they clearly are still having a good time.Jake Smolinski singled and scored the deciding run in the third inning, rookie Zach Neal earned his first career win as a starter and Oakland held on to beat Baltimore 2-1 on Tuesday night.“You’re going to go through waves and we’re on a good wave right now,” Madson said. “Everybody’s feeding off each other, and it’s fun when everybody’s doing that.”Danny Valencia and Khris Davis drove in a run apiece as the A’s won consecutive games for the first time since July 26-27 to keep Wade Miley winless in an Orioles uniform.Smolinksi finished with two hits and two walks while Marcus Semien singled and scored as Oakland won its second straight one-run game from AL East-leading Baltimore.The Orioles remain percentage points ahead of Toronto, which lost earlier Tuesday night.Like they did in the series opener, the A’s got strong starting pitching, solid relief and just enough hitting.Neal (2-1) allowed one run over 5 1-3 innings and retired 16 of the 18 batters he faced to win his second career start and first since May 25. He gave up Adam Jones’ home run in the fourth and a double to Jonathan Schoop leading off the sixth.“Boy that was impressive,” Melvin said.
