SS Chad Pinder (left hamstring) played in his fourth rehab game for Triple-A Nashville on Sunday afternoon, when he went 0-for-3 while playing center field. Pinder is 2-for-13 since joining Nashville last Tuesday. Manager Bob Melvin said Saturday he hopes Pinder can rejoin the Athletics during a homestand that begins Friday. Pinder was injured June 23 and was placed on the 10-day disabled list the next day. He is batting .234 with nine homers and 25 RBIs in 47 games this season.-RHP Chris Bassitt (Tommy John surgery) continued his rehab Sunday afternoon, when he tossed a perfect inning of relief for Triple-A Nashville. It was the eighth straight time Bassitt has thrown two innings or fewer dating back to June 28. Bassitt has made 23 of his 29 big league appearances as a starter but is being groomed to work in the bullpen for the Athletics upon his return. He has allowed four runs in 4 2/3 innings over three relief appearances for Nashville and is 1-2 with a 5.46 ERA in 13 games (nine starts) between Nashville and Class A Stockton. Bassitt was 0-2 with a 6.11 ERA in five starts for the Athletics last season before undergoing surgery on May 6, 2016.-RHP Ryan Dull (strained right knee) could return to the Athletics before the end of their four-game series against the Blue Jays, which begins Monday. Dull began a rehab assignment with Triple-A Nashville last Wednesday and has struck out two over two perfect innings. He is expected to pitch at least once more for Nashville before the Athletics consider bringing him back to the majors. Dull, who was placed on the 10-day disabled list May 20, is 2-2 with a 6.32 ERA in 18 games this season.
