The right-handed batter has appeared in 872 games across seven Major League seasons between Cincinnati (2011-15) and Chicago-AL (2016-17). In 2012, he finished third in National League "Rookie of the Year" voting. Frazier owns a career .247 batting average (777-for-3,151) with 435R, 161 doubles, 11 triples, 164HR, 466RBI, 301BB and 62SB.

The right-hander was originally selected by the Yankees in the 17th round of the 2006 First-Year Player Draft, making his Major League debut with the club in 2008. Over seven seasons with the Yankees (2008-14), he went 25-19 with 47 saves (in 62 opportunities), a 2.81 ERA (393.1IP, 123ER) and 524K in 402 relief appearances.

Kahnle (pronounced KAYN-lee), 27, went 1-3 with a 2.50 ERA (36.0IP, 10ER) and 60K, while walking just seven batters over 37 relief appearances with the White Sox.

Since May 6, he has struck out at least one batter in each of his 26 appearances, the second-longest such streak by any pitcher this season behind only Milwaukee's Corey Knebel's active 45-game stretch. He is one of just three pitchers this season with at least 60K and fewer than 10BB, joining Los Angeles-NL's Kenley Jansen and Boston's Craig Kimbrel.
