The Giants designated Quintana for assignment on Thursday.
Quintana, who was grabbed off waivers by the Giants in August and pitched 9.2 innings with a 12:6 K:BB ratio, has been removed from the 40-man roster with four games remaining in the regular season.
Quintana pitched seven scoreless innings against the Reds, allowing three hits and walking five batters while striking out five. He had no say in the matter.
Quintana was forced to settle for a no-decision because neither team could generate much offensive production during Sunday’s matchup.
Over his last four starts, the southpaw has a 1.17 ERA in 23 innings, but only one win. On Saturday, he is scheduled to start against the Cardinals at home.
Quintana (1-1) grabbed the win in Monday’s triumph over the Dodgers after pitching six scoreless innings, allowing two hits and four walks.
Quintana had his best start of the season, blanking the Dodgers in six innings. He has now allowed three or fewer runs in each of his first six starts in 2022.
Quintana has a 2.70 ERA, 1.20 WHIP, and 25 strikeouts in his first 30 innings with the Pirates after joining them this past winter. On Sunday, he’ll take on the Reds.
Quintana pitched five innings in a 3-2 defeat to the Brewers, allowing one run on four hits and not factoring in the decision. He struck out nine batters while walking none.
Quintana gave up a leadoff home run to Andrew McCutchen, then settled down and pitched five good innings, striking out a season-high nine batters.
Quintana has a 3.32 ERA and a 17:8 K:BB ratio in 19 innings in his first four starts with Pittsburgh. His next start is expected to be at Detroit on Wednesday.
