The Rays are going to shut Glasnow down from throwing for seven to 10 days before re-evaluating the 25-year-old. Over eight starts this season, the starter is 6-1 with an AL-leading 1.86 ERA in his first season with the Rays. He came over in an off-season trade from the Pittsburgh Pirates, where he never had an ERA under four. The team added catcher Travis d'Arnaud from the Los Angeles Dodgers in a trade on Friday night and he took Glasnow's roster spot.
Elsewhere, the Seattle Mariners have cooled off in a major way since their surprisingly hot start to the season, and they watched their star hurler go down in Boston. One day after the Boston Red Sox erased a 4-0 deficit by knocking Felix Hernandez around at Fenway Park, the Mariners placed the right-hander on the injured list on Sunday with a strained right shoulder. On Saturday, which was a 9-5 loss in Boston, "King Felix" did become the 36th pitcher in major league history to reach 2,500 career strikeouts. He did so by striking out Michael Chavis, as he joined C.C. Sabathia, Justin Verlander, and Max Scherzer as the only active pitchers in that club.
With the two consecutive losses in Boston this weekend, the Mariners have now dropped 14 of their past 18 games overall, and were outscored, 23-6, in the first two games of the Red Sox series. Those losses now have them two games under .500, but still in second place in the AL West behind the Houston Astros. The M's called up pitchers Dan Altavilla and Parker Markel to fill the roster spots heading in to their series finale with the Red Sox on Sunday afternoon.
