Kendall Graveman pitches stingy A’s to series win over Indians [...] Graveman is 9-2 with a 3.33 ERA over his past 16 starts, and Wednesday, he earned his 10th victory of the season as Oakland beat the Indians 5-1. The only blemish on Graveman’s day was Roberto Perez’s two-out homer in the seventh, which ended Graveman’s string of scoreless innings at 16. The A’s continued to get nice work from rookie third baseman Ryon Healy, whose hitting streak is at 11 games after an RBI single in the second. Rookie shortstop Chad Pinder added his second RBI in as many games, a sac fly, and Danny Valencia’s pop-up to first fell in behind first baseman Carlos Santana sent in two runs. The pop-up initially was ruled a hit but was changed to an error, ending Valencia’s streak of multi-hit games in starts at seven, the A’s longest streak since Randy Velarde had seven in 1999. Graveman gave up six hits and two walks while striking out two, and he has walked no more than two batters in 14 of his past 15 starts. Henderson Alvarez (shoulder) will throw an inning in a rehab appearances with rookie-ball Arizona on Saturday.
