Houston Astros left-handed pitching prospect AJ Blubaugh was called up to join the Astros in Miami on Tuesday, according to Matt Kawahara of the Houston Chronicle. Left-handed pitcher John Rooney was optioned to Triple-A Sugar Land in a corresponding move. Blubaugh immediately came in to pitch in relief after Steven Okert and Kaleb Ort combined for two innings to open the game. The lefty pitch effectively in long relief, allowing two runs on three hits and one walk while striking out five. The 25-year-old conceded a good amount of hard contact, however, including two home runs. He generated seven whiffs on 36 swings, leaning on his three-pitch mix of a four-seamer, changeup, and sweeper. This was Blubaugh's second appearance of the season with the Astros, with the previous coming back in April when he allowed seven runs (two earned) in four innings against the Tigers. His numbers for the season at Triple-A Sugar Land have been poor, with a 5.76 ERA, 1.62 WHIP, and 8.7% K-BB% in 89 innings.

The Houston Astros have optioned right-handed pitching prospect A.J. Blubaugh to Triple-A Sugar Land. Blubaugh was promoted to the majors to make a spot start on Wednesday against the Detroit Tigers. In this outing, Blubaugh logged four innings of seven-run ball. However, only two of those runs were earned. He also allowed five hits and posted a strong 6:1 K:BB. Blubaugh was given the call to take Hayden Wesneski's spot. However, given this transaction, Wesneski should be in line to return to action next week. Earlier in the season, Blubaugh logged 21 innings to the tune of a 3.86 ERA with a 1.38 WHIP. During this stint, he struck out 28 batters and served up just 10 walks. Fantasy managers should not consider stashing Blubaugh in any formats, as he may not return to the majors until he is needed as an injury replacement.

The Houston Astros are expected to call up starting pitching prospect A.J. Blubaugh from Triple-A Sugar Land to make his big-league debut in Wednesday's game against the Tigers, per the Athletic's Chandler Rome. He will be making a spot start for Hayden Wesneski, whom manager Joe Espada said "needs a couple more days to recover from his last start." The 24-year-old pitching prospect is not on the 40-man roster, so the Astros will need to make a corresponding move. Blubaugh currently owns a 4.29 ERA in 21 innings pitched at Triple-A. He has flashed high strikeout upside but also some walk issues throughout his minor-league career. While Blubaugh will have a solid offense backing him, fantasy managers should first wait to see how his debut goes and then see if he can carve out a role with the team before trusting him.
