Mariners General Manager Jerry Dipoto announced today that the club has acquired left-handed pitcher Dillon Overton from Oakland in exchange for minor league catcher Jason Goldstein. To make room on the 40-man roster, catcher Jesus Sucre has been designated for assignment.

The Mariners Major League, 40-man, roster remains full.

“Dillon has been successful at every level of the minor leagues,” Dipoto said. “He is a young, controllable pitcher with Major League upside who adds to our depth.”

Overton, 25 (turns 26 on Aug. 17) went 13–5 with a 3.29 ERA (46 ER, 125.2 IP) with 105 strikeouts and 31 walks in 21 games (20 starts) with AAA Nashville last season. Among qualifying AAA pitchers last season, the 6-foot-2, 175-pound left-hander ranked 3rd in wins (13) and 8th in ERA (3.29). He entered the season ranked as the Athletics 8th-best prospect by Baseball America. Overton was selected by Oakland on June 25 and made his Major League debut in a start at Los Angeles -AL later that day (6/25). In 7 games (5 starts) with the Athletics last season, he went 1–3 with an 11.47 ERA (31 ER, 24.1 IP) with 17 strikeouts and 7 walks.

The native of Clinton, OK, was originally selected by Boston in the 26th round of the 2010 MLB First-Year Player Draft but did not sign. After three seasons at the University of Oklahoma, he was selected by Oakland in the 2nd round of the 2013 MLB First-Year Player Draft. In parts of 3 minor league seasons in the Athletics organization (2014–16), he compiled a career record of 20–14 with a 3.18 ERA (102 ER, 288.2 IP) with 264 strikeouts and 62 walks in 60 career appearances (57 starts). Overton made his professional debut with the AZL Athletics in 2014 after undergoing “Tommy John” surgery on his left elbow on July 9, 2013.

Sucre, 28, appeared in only 9 games over two stints with Seattle in 2016 due to an injury (7/6–20 & 9/2-end of season), batting .480 (12x25) with 4 runs scored, 2 doubles, 1 home run, 5 RBI and 2 walks. He was on the 60-day disabled list from March 1 to July 6 after having surgery to repair damage in his right ankle on Jan. 26, 2016 in Seattle. He sustained a fractured right fibula during winter ball in Venezuela. In two stints with AAA Tacoma after being activated from the disabled list, Sucre hit .300 (24x80) with 6 runs scored, 3 doubles, 1 triple, 10 RBI and 3 walks.

Sucre was signed by the Mariners as a minor league free on July 19, 2011. Over parts of four seasons with Seattle (2013–16), he hit .209 (50x239) with 18 runs scored, 10 doubles, 2 home runs, 20 RBI and 10 walks in 88 career games. Sucre was originally signed by the Atlanta Braves as a non-drafted free agent on May 20, 2005.

Goldstein, 22, split his first professional season with the Arizona League Mariners (6/17–7/13) and Short-A Everett (7/14-end of season). In 19 combined games he hit .279 (17x61) with 7 runs scored, 2 doubles, 6 RBI, 5 walks and 1 stolen base. Goldstein was the Mariners 9th round selection in the 2016 MLB First-Year Player draft out of University of Illinois.
