"Yovani has been a huge part of the Brewers organization and has left a mark as one of the best pitchers in franchise history," said Melvin. "He is a great competitor and professional who will be missed. At the same time, we have added three young and talented players to our organization.
Knebel and Sardinas have a chance to be on our Major League club in 2015 and Diplan is one of the top arms to come out of the Dominican Republic over the last couple of years."
Knebel, 23, owns a 7-2 career minor-league record with a sterling 1.65 ERA and 18 saves in 65 relief appearances. He has 104 career strikeouts over just 76.1 innings pitched in the minor leagues while holding opponents to a .145 batting average. He made his Major League debut this season as he appeared in 8 games with Detroit.
Selected by Detroit in Competitive Balance Round A of the 2013 First-Year Player Draft, Knebel was traded to Texas this past July 23 in the deal that brought right-handed pitcher Joakim Soria to the Tigers. He enjoyed a three-year career as the closer at the University of Texas, collecting 37 saves, second-most in school history.
Sardinas, 21, made his Major League debut this season and batted .261 with 8 RBI and 5 stolen bases in 43 games during three different stints with the Rangers. The switch hitter made 31 starts (15g at 2B, 8g at SS, 4g at 3B, 4g at DH) and was the third-youngest player to appear in a Major League game in 2014. Entering last season, he was ranked as the 76th-best prospect on MLB.com's top 100 list. Entering 2015, he was ranked as the seventh-best prospect in the Rangers organization according to Baseball America.
Diplan, 18, completed his first pro season in 2014 and went 7-2 with a 1.54 ERA in 13 starts for the Dominican Summer League Rangers.
His ERA ranked sixth in the DSL. He held opponents to a .155 batting average with 57 strikeouts in 64.1 innings pitched. Diplan was an All-Star in the 2013 Dominican Prospect League and member of the DPL Elite Travel Team that toured Florida during Spring Training that year. He was rated by Baseball America as the sixth-best international prospect and MLB.com rated him eighth.
Gallardo, 28, went 89-64 with a 3.69 ERA in 214 games (211 starts) during parts of eight seasons with the Brewers. The 2010 All-Star is the all-time franchise leader in strikeouts (1,226). He went 8-11 with a 3.51 ERA in 32 starts last season.
