ARLINGTON, Texas — Drew Smyly's return to the rotation Sunday did not go well, which fit in with the rest of the weekend for the Rays as they lost 5-3 and were swept in the three-game series by the Rangers.Smyly, starting for the first time since May 5 as he rehabbed a shoulder injury, lasted only four innings while allowing five runs, needing 95 pitches to get the 12 outs and twice giving up the lead. He threw 20 or more pitches in each of his four innings.And that proved too much for the Rays to overcome even though they rapped out 11 hits, as several chances were squandered.The third straight loss dropped the Rays back under .500 at 58-59 as they head next to Houston for a four-game series with the American League West-leading Astros that starts Monday.Though the Rays gave Smyly a 1-0 lead before he took the mound, he handed it right back by allowing two runs, starting with a five-pitch walk to leadoff man Delino DeShields and followed by an RBI double by Shin-Soo Choo and a sac fly by Adrian Beltre. Smyly threw 25 pitches in the first.The Rays went up 3-2 in the second, on a triple by Desmond Jennings, a "hustle" double by Kevin Kiermaier and a single by John Jaso. But Smyly squandered it again, allowing the Rangers to scratch out a run in the second then allowing homers in the third to Beltre and the fourth to rookie Ryan Strausborger, the first of his career.Alex Colome did a good job keeping the Rays' shorthanded bullpen intact, working three innings and allowing only two hits.The Rays had several opportunities to add runs. In the fifth they had two on with no outs, but Asdrubal Cabrera and Jennings failed to put the ball in play, striking out against Yovani Gallardo. Then they had Kiermaier on second with no outs in the sixth, but Curt Casali and Brandon Guyer struck out and Richie Shaffer popped out.Smyly was impressive last season after coming to the Rays as the primary immediate return from Detroit for David Price, going 3-1 with a 1.70 ERA in seven starts before the Rays shut him down in early September, ostensibly to limit his innings and prevent injury.But this season has been a mess. An offseason finger issue limited his workload at the start of spring training, a bout of shoulder tendinitis forced him to miss the first three weeks of the season and after just three starts (0-1, 2.70) he was sidelined by more severe shoulder issues, including discovery of a torn labrum that made season-ending surgery part of the conversation.He opted instead for rehab, spending three months under the supervision of head athletic trainer Ron Porterfield to strengthen and stabilize the shoulder.
