Red Sox acquire right-handed pitcher Brad Ziegler from Arizona

Send right-handed pitcher Jose Almonte and infielder Luis Alejando Basabe to Diamondbacks

BOSTON, MA - The Boston Red Sox today acquired right-handed pitcher Brad Ziegler from the Arizona Diamondbacks in exchange for two minor league players: right-handed pitcher Jose Almonte and infielder Luis Alejandro Basabe.

To make room for Ziegler on the 40-man roster, left fielder/catcher Blake Swihart was transferred to the 60-day disabled list (left ankle sprain).

President of Baseball Operations David Dombrowski made the announcement.

Ziegler, 36, entered Friday with a 2-3 record and 2.82 ERA (12 ER/38.1 IP) in 36 relief appearances, converting 18 of 20 save opportunities and finishing 30 games for the Diamondbacks. The right-hander has recorded 27 strikeouts and allowed only one home run this season, ranking sixth among National League relievers in homers allowed per 9.0 innings pitched (0.23). In 18 appearances on the road, Ziegler has posted a 0.89 ERA (2 ER/20.1 IP) and converted 11 of 12 save chances.

Originally signed by Philadelphia as a 20th-round selection in the 2003 June Draft, Ziegler is 32-24 with 81 saves and a 2.49 ERA (157 ER/567.0 IP) in 571 career appearances, all in relief with the Oakland A's (2008-11) and Diamondbacks (2011-16). He leads all major leaguers in pitching appearances and grounded into double play percentage (20.8, 108 of 520) since the start of 2008, and his ground ball rate of 67.4 percent is the highest among active relief pitchers (min. 750 batters faced). Ziegler was one of only three pitchers to make at least 60 appearances in each season from 2009-15, joining Matt Thornton and Luke Gregerson.

Born in Pratt, KS, Ziegler has the lowest career ERA in Diamondbacks history among pitchers who have appeared in at least 100 games for the club (2.49). He has also made more appearances than any pitcher in Arizona history (348) and holds the club's single-season records for relief ERA (1.85, 2015) and save percentage (93.8, 30-for-32, 2015). Ziegler did not allow a run in his first 39.0 innings with the A's in 2008, setting a major league record for consecutive scoreless innings to begin a career. He converted 43 consecutive save opportunities from May 29, 2015 to June 20, 2016, the longest such streak in Arizona franchise history and the seventh-longest in major league history.

Almonte, 20, is 2-2 with a 3.91 ERA (23 ER/53.0 IP) in 10 starts for Single-A Greenville this year, his fourth season in the Red Sox organization (2013-16) since being signed as an international free agent in 2012. The Dominican native has made 47 minor league appearances (44 starts) in his career, going 10-11 with a 3.24 ERA (78 ER/216.2 IP), 185 strikeouts, and a .218 opponent batting average. Almonte spent his entire 2015 season with short-season Single-A Lowell, leading the Spinners in innings (65.2) and strikeouts (64) and ranking sixth in the Red Sox organization in ERA (3.43).

Basabe, 19, has played 63 games with Greenville this season, hitting .311 (70-for-225) with 39 runs, 16 doubles, four triples, four home runs, 24 RBI, 14 stolen bases, and a .414 on-base percentage, earning him mid-season All-Star honors in the South Atlantic League. Signed by the Red Sox as an international free agent in 2012, the switch-hitter has played 178 games over four seasons in the organization, hitting .255 (148-for-580) with 105 runs, 29 doubles, nine triples, five home runs, 50 RBI, and 40 stolen bases. The Venezuelan native has played primarily at second base (140 games, 119 starts) and has also appeared in 35 games at shortstop (16 starts).

Swihart, 24, was placed on the 15-day disabled list on June 5. He made his first career Opening Day roster in 2016 and has appeared in 19 games with the Red Sox this season, batting .258 (16-for-62) with three triples and a .365 on-base percentage. Each of his last 13 starts for Boston has been made in left field, where he has recorded one assist and no errors in 31 total chances. He has also hit .243 (25-for-103) with four doubles and a home run in 29 games with Triple-A Pawtucket, making 14 starts at catcher and 11 in left field. Selected by Boston in the first round of the 2011 June Draft, the switch-hitter has appeared in 103 major league games in two seasons (2015-16), hitting .271 (95-for-350) with 17 doubles, four triples, and five home runs.
