After another weekend of base-running blunders, the Oakland A's made a coaching change. On Monday morning, the A's replaced longtime third base coach Mike Gallego with former third base coach and current infield instructor Ron Washington. Gallego had been the A's third base coach since 2009 and had the second-longest tenure of any coach on the A's big league staff, behind first base coach Tye Waller.
Earlier this season, the A's hired Washington to coach their infielders after Oakland's infield defenders got off to a very slow start. The A's lead the league in errors with 100, including 31 by shortstop Marcus Semien and 20 by third baseman Brett Lawrie. Gallego had been the infield coach before Washington's arrival. The A's have also had 19 runners thrown out at home this season and had several base-running misadventures this weekend.
Despite those obvious struggles, it was surprising to see the A's let Gallego go during the season given his longtime tenure with the organization as a coach and a player. The A's haven't made an in-season coaching change since 2011, when they fired manager Bob Geren and replaced him with current manager Bob Melvin.
In addition to the switch in the coaching staff, the A's announced that RHP Kendall Graveman was placed on the disabled list with a strained left oblique. The A's won't need another starter to replace Graveman for a few days, so Oakland recalled corner infielder Max Muncy from Nashville. Muncy is batting .297 over his last 10 games with Nashville and .333 for the month of August. This is his third stint with the A's this season. He has a .207/.275/.378 line with two homers in his first 35 major-league games.
In other news, Midland RockHounds' infielder Ryon Healy was named the Texas League's Player of the Week for the second time this season. Healy has an eight-game hitting streak and he has 10 hits over his last three games (17 at-bats). Healy is batting .307 in 113 games for Midland this season. This is his first year at the Double-A level.
