Bursitis keeps Nationals' Bryce Harper out of lineup Washington Nationals outfielder Bryce Harper was out of Monday's lineup against the Baltimore Orioles because of bursitis in his left knee. Manager Davey Johnson said Harper aggravated his sore knee in Sunday's 6-1 win over the Philadelphia Phillies with multiple headfirst slides and by hitting a foul ball off it. Team medical director Wiemi Douoguih said the outfielder has inflammation of the bursa sac in front of his knee, which he anticipates clearing up in a couple of days. Harper underwent an MRI exam that showed some soft tissue swelling, but no structural damage, Douoguih said. The Seattle Mariners sent former No. 2 overall pick Dustin Ackley to the minors in the hope he can rediscover his swing there. The Mariners optioned the 25-year-old second baseman to triple-A Tacoma before opening a series against the San Diego Padres and selected prospect Nick Franklin from Tacoma to take his place. Ackley is the second young player the Mariners were counting on this season to be sent down, joining Jesus Montero. San Diego Padres catcher Yasmani Grandal is eligible to be reinstated Tuesday from a 50-game suspension for a positive testosterone test that called into question just how good his rookie numbers were. The Chicago Cubs put reliever Kyuji Fujikawa on the 15-day disabled list because of a right forearm injury. The right-hander will undergo an MRI exam Tuesday to see if the injury is related to a muscle strain from April.
