Red Sox acquired LHP Erik Miller and OF Carlos Gutierrez from the Giants for INF Marcelo Mayer.

It’s a tough break for Miller’s immediate fantasy outlook as he’ll be stuck behind Aroldis Chapman and Garrett Whitlock in Boston’s high-leverage mix. However, he provides the Red Sox with another reliable late-inning option as they attempt to make a real playoff push following the best month in franchise history. The 28-year-old lefty boasts a strong 2.76 ERA, 1.38 WHIP and 45/22 K/BB ratio across 32 2/3 innings this season. His departure obviously leaves San Francisco’s closing situation in flux.
