Athletic trainers along with manager Joe Maddon attended to him and eventually walked him back to the dugout for further evaluation.
The Cubs, though, thought there was intent behind the pitch.
In the aftermath of the errant pitch, Cubs hitting coach Chili Davis and assistant hitting coach Andy Haines were ejected.
Umpire Cory Blaser signaled safe, but the call was reversed about 90 seconds later. Bettis is coming off a gem at Pittsburgh in which he pitched 7 ⅓ scoreless innings in a 2-0 victory.
Tommy La Stella, Kyle Schwarber and Victor Caratini hit RBI singles later in the first off Marquez (1-2).
German Marquez looked sharp right away but it all unraveled after a high fastball ran too far inside and hit Kris Bryant in the helmet.
Jose Quintana (2-1) allowed four runs and eight hits in 5 1/3 innings.
Once the dust had settled, the Rockies many rallies came up just short, dropping the game 9-7, and losing the series to the Chicago Cubs, meaning they are still looking for their first home series win. Morrow got his fourth save. Javier Baez's seventh homer made it 4-0 in the second, and Jason Heyward had a two-run single in the third to give the Cubs a 6-0 lead. He struck out seven, raising his big league total to 1,004. Also, outfielder Gerardo Parra began to serve his four-game suspension for his involvement in the benches-clearing brawl against the San Diego Padres earlier in the season and this certainly threw a wrench into how Colorado built their line up. He slashed.295/.409/.537 with 29 home runs and 73 RBI in 2017 and has followed up with a.319 average and 11 RBI in 18 games of 2018. The Cubs then scored two runs on a groundout to the pitcher hit by Albert Almora Jr.
