Calhoun had played at Triple-A Oklahoma City this season. Davis started at Class-A Great Lakes and was recently promoted to Class-A Rancho Cucamonga. Alexy was pitching in his first full season at Great Lakes.
Darvish, who will turn 31 in August, had been the subject of trade rumors for the last month or so. He will be a free agent at the end of this season so for now, the Dodgers are acquiring about one-third of the season and whatever post-season follows.
As the ace of the Rangers staff, Darvish has had a mixed season, but one thing he does do is give you some length from a right-handed pitcher. He has pitched six or more innings in 16 of his 22 starts this season. Darvish has accumulated 137 innings pitched, averaging 9.7 strikeouts per nine innings and his WHIP has been stable at 1.168.
Prior to this season, Darvish was heading into his free-agent-to-be season with a great track record especially after recovering from his 2015 Tommy John surgery so well.
In 2016, Darvish averaged 11.8 strikeouts per nine innings and had a 3.41 ERA (3.09) FIP in 100⅓ innings.
To make room on the 40-man roster, the Dodgers designated infielder/outfielder Mike Freeman for assignment. Freeman had played four games with the Dodgers at the end of June, he was playing for Oklahoma City at the time of this transaction.
