Hazelbaker, 30, had been acquired earlier in the season from the Diamondbacks, but had yet to see any action at the MLB level. In 230 plate appearances at Triple-A on the season, he carries a .190/.278/.366 batting line. Though he has produced at a 116 OPS+ rate in 285 total major-league plate appearances, Hazelbaker is still waiting for his next crack at the game’s highest level.
As for Kolarek, he will get another chance after struggling in a brief debut in 2017. The 29-year-old has certainly earned his return. In 42 1/3 Triple-A frames over 29 appearances, he owns a 1.70 ERA with 10.6 K/9 and 2.1 BB/9 along with a hefty 62.7% groundball rate.
