Let’s cap off a busy Wednesday of transactions with perhaps the most surprising non-tender of all.

Rob Biertempfel of the Pittsburgh Tribune-Review reports that the Pirates have parted ways with first baseman Pedro Alvarez, who was due a raise in his final year of arbitration from the $5.75 million he made in 2015. He is officially a free agent, eligible to sign with any team.

Alvarez can be a frustrating regular — he strikes out a ton and struggles mightily against left-handers — but the 28-year-old Dominican slugger has averaged 28 home runs and 80 RBI per season since 2012.

American League teams should be rushing in with offers to make him their DH.

Pittsburgh also non-tendered outfielder Jaff Decker on Wednesday.
