Thompson will start Tuesday's game against the Pirates, Meghan Montemurro of the Chicago Tribune reports.
Thompson made his first start of the season Wednesday against the Padres, allowing two runs on five hits and a pair of walks while fanning one over four innings. He also threw a season-high 61 pitches, so it will be interesting to see if the Cubs stretch him out past that number in this favorable matchup, as Thompson came up through the minors as a starting pitcher. The 27-year-old righty has a 1.67 ERA, 1.07 WHIP and 22:10 K:BB in 27 innings this season.
