The Orioles held a moment of silence for former general manager Frank Cashen, who died Monday at age 88. … Monday's announced attendance of 15,252 is the lowest of the year so far at Camden Yards. The previous low was the first game of Friday's doubleheader (15,614). ... Left-hander T.J. McFarland likely will make a spot start Tuesday against the Rangers, unless the Orioles need him to pitch Monday, Showalter said. Right-hander Chris Tillman then will start Wednesday and left-hander Wei-Yin Chen on Thursday. … Infielder Michael Almanzar, the club's Rule 5 draft pick in December, was designated for assignment Monday. Eventually, he must be offered back to the Red Sox for half the original sale price of $50,000, but each of the other 28 major league teams can first attempt to claim him and put him on its 25-man roster. He had been on the 60-day disabled list with left knee tendinitis.
