"We have been clear that one of our top priorities this off-season was to continue to bolster our starting rotation," Dipoto said. "Today's moves allowed us to add an experienced pitcher to our starting group. Drew took the ball 30 times last season, threw over 175 innings and is a proven performer in the American League. He's a good fit for our club."
Smyly, 27, established career-highs last season with 30 starts, 175.1 innings and 167 strikeouts. He finished the season 7-12 with a 4.88 ERA (95 ER, 175.1 IP) with 167 strikeouts in 30 starts with Tampa Bay. Among left-handed pitchers last season, Smyly ranked 7th in fewest walks-per-9.0-innings with a mark of 2.52 (49 BB, 175.1 IP). Over his final 12 starts of the season, he was 5-1 with a 3.73 ERA (29 ER, 70.0 IP) after opening the year 2-11 with a 5.64 ERA (66 ER, 105.1 IP) in his first 18 starts. He recorded four double-digit strikeout games, a mark topped by only three American League pitchers: Boston's David Price (7), Detroit's Justin Verlander (7) and Tampa Bay's Chris Archer (6). He was one of 10 American League left-handers to make 30 starts and toss at least 175.1 innings last season.
In five Major League seasons with Detroit (2012-14) and Tampa Bay (2014-16), the left-hander is 31-27 with a 3.74 ERA (237 ER, 570.1 IP) with 552 strikeouts in 156 games, including 85 starts. He was originally selected by Detroit in the 2nd round of the 2010 MLB First-Year Player Draft and was traded to Tampa Bay as part of the David Price deal between the Tigers, Rays and Mariners on July 31, 2014.
Smith, 23, was acquired by Seattle from Atlanta in a trade earlier today. He made his Major League debut with the Braves in 2016, appearing in 72 games and hitting .238 (45x189) with 7 doubles, 4 triples, 3 home runs and 22 RBI while recording 16 stolen bases. He played all three outfield positions, appearing in center field (35 games), left field (22 games) and right field (1 game) and committing just 1 error and collecting 5 assists.
