Ariel Pena begat Sam Freeman.
Sam Freeman begat Michael Kirkman.
And now, Michael Kirkman has begat Jhan Marinez.
The final spot in the Milwaukee Brewers' bullpen, and essentially their roster as a whole, has been something of a revolving door through the first 35 games of the season. So I guess we shouldn't have been surprised when it was announced late last night that Slingin' David Stearns had made yet another personnel move, acquiring right-handed reliever Jhan Marinez from the Tampa Bay Rays in exchange for cash.
Marinez, 27, was originally signed as an amateur free agent out of the Dominican Republic in 2006 by the Marlins. He's a hard thrower who has averaged over 95 MPH on his fastball during his career, though he's only got a two-pitch arsenal including his heater and a mid-80s slider. Marinez has made only nine big league appearances in his 11 year career: four games with Miami in 2010, two games with the White Sox in 2012, and three games with the Rays this season. Cumulatively he's allowed three earned runs in 9.0 innings with seven strikeouts and five walks.
Marinez does have a lengthy track record of missing bat in the minor leagues, however, having posted a career 25.1% strikeout rate across 432.1 innings covering 312 appearances (9 starts). Like many hard throwers he has also battled significant control issues, having walked 13.5% of batters while allowing a career 4.00 ERA. He's got a nice track record of success at the minors' highest level and owns a 3.63 ERA and 186:94 K/BB ratio in 178.1 innings at AAA.
To make room on the active roster for the addition of Marinez, the club designated LHP Michael Kirkman for assignment. Milwaukee claimed Kirkman just over a week ago and he made just one appearance in a Brewers' uniform, allowing a single run in an inning against the Marlins on May 9th. Milwaukee will now have 10 days to either trade, release, or attempt to pass Kirkman through waivers and outright him to the minor leagues.
