To make room on their roster for Locke, the Pirates optioned outfielder Alex Presley to Triple-A.
Charlie Wilmoth of Bucs Dugout speculates that the move is a "short-term measure" to aid Pittsburgh’s core of relievers. He notes the Pirates’ bullpen "could probably use an extra arm right now, especially after the late-inning blowup Tuesday night."
Locke, 24, has started four games for the Pirates this season. Over sixteen and two-thirds innings pitched, he has maintained an ERA of 6.48 with ten walks to five strikeouts.
Locke has also started twenty-one games for the Pirates’ Triple-A affiliate this season, posting an ERA of 2.66 with 8.1 SO/9 and 2.7 BB/9.
Presley’s hit .234/.275/.387 with nine doubles, four triples and eight home runs over 269 at-bats for the Pirates this season.
