Hunter, 29 this month, has a 3.63 ERA, 6.4 K/9, 2.2 BB/9, 0.60 HR/9, and 46.3% groundball rate in 60 2/3 innings for the Orioles this year. Hunter joined the Orioles four years ago along with Chris Davis, in a trade with the Rangers for Koji Uehara. Since 2013, he has a 3.05 ERA in 191 2/3 innings out of the Orioles’ bullpen. He’s earning $4.65MM this year, and will become a free agent after the season. He’s the lone addition to a Cubs bullpen that includes Hector Rondon, Pedro Strop, Jason Motte, Justin Grimm, Rafael Soriano, and James Russell.
Lake, 25, has struggled in the Majors with a .241/.283/.380 career line. He has played well at Triple-A this year, with a .315/.404/.472 line in 231 plate appearances. Prior to the 2013 season, back when Lake was still an infield prospect, Baseball America said he had “tantalizing tools and inconsistent performance.” If Lake does become a useful big leaguer, he’ll be a late bloomer. He’s the second outfielder the Orioles acquired today, as they made a bigger splash earlier by acquiring Gerardo Parra from the Brewers.
