Top prospect Konnor Griffin made his MLB debut for the Pittsburgh Pirates on June 11 after being recalled from Triple-A Indianapolis.

Griffin got the start at shortstop as the Los Angeles Dodgers visited PNC Park, but it was Los Angeles that controlled the game, routing Pittsburgh 11-3 behind Tyler Glasnow. Bubba Chandler lasted just 2.2 innings, allowing six earned runs. Batting ninth, Griffin recorded one hit in four plate appearances with one strikeout.

Since his debut, Griffin has impressed, hitting .314 with two home runs and nine RBI over 35 at-bats in June, earning NL Rookie of the Month honors.

The Pirates (48-38) remain in the division race, sitting 1.5 games behind the first-place Chicago Cubs (50-37) and Cincinnati Reds (49-36).
