MLBTR has rounded up the Andrew Miller rumors. This is a free site so here is entire story:
The Red Sox are willing to move southpaw reliever Andrew Miller in a trade, according to multiple reports. Rob Biertempfel of the Pittsburgh Tribune-Review (via Twitter) says that Boston is shopping the lefty, adding that the Pirates have been scouting the club for weeks and have interest in Miller. Likewise, David O’Brien of the Atlanta Journal-Constitution hears (Twitter link) that Miller is available and reiterates that the Braves are still on him, with Jon Heyman of CBSSports.com reporting that Miller is Atlanta’s “prime bullpen target.”
Miller, 29, could well be the most impactful late-inning lefty available, as I noted yesterday in a breakdown of the left-handed relief market. He owns stellar peripherals (14.5 K/9 vs. 2.8 BB/9, 51.9% groundball rate) to go along with excellent results (2.31 ERA). Unsurprisingly, ERA estimators are also a fan: Miller sports a 1.77 FIP, 1.82 xFIP, and 1.47 SIERA.
This is undoubtedly Miller’s finest season, as he has only once sported an ERA of below three earned per nine (last year) and struggled earlier in his career, when he was use a starter. But his results have steadily improved since he shifted to the pen, and Miller has plenty of value to a contending team that does not want to take on long-term commitments. He is earning just $1.9MM this year and will hit the open market following the end of the season.
