Pittsburgh also acquired Lake Bachar from the Marlins shortly after, sending over Triple-A pitcher Brandan Bidois, High-A outfielder Brian Sanchez, and Single-A shortstop Hyun Seung Lee.
Bachar is tossing a 3.84 ERA with 61 strikeouts through 58.2 innings.
Yates, 39, has a 3.95 ERA with three saves in 31 games this season. He has 36 strikeouts in 27.1 innings, giving up 12 walks and 20 hits. The two-time All-Star joins Luke Weaver in Pittsburgh as the Pirates beefed up their bullpen at the trade deadline.
Robinson, 23, has a 4.55 ERA this season in the minors with 78 strikeouts through 83 innings, giving up 34 walks and 85 hits. It's worth noting that Robinson has a 6.43 ERA at the Double-A level after working his way up through Single-A and High-A.
