Rockies OF Randal Grichuk had sports hernia surgery

Rockies outfielder Randal Grichuk tells Thomas Harding of MLB.com that he underwent surgery for a bilateral sports hernia a week ago. Grichuk said that he could be ready to return to game action in about six weeks in a best-case scenario. Since Opening Day is roughly six weeks away, it’s possible he could be ready by then, but it seems that missing some time will now be a distinct possibility.

“It was one of those things that was not going to get better, and it was a matter of when was it going to get worse,” Grichuk said. “I’d much rather miss spring training, get back late spring and miss only a little bit of [regular-season] time than try to play through the grind of trying to play every day, 100% effort, then let it flare in April and miss two or three months of the season.”

Grichuk, 31, came over to the Rockies a year ago in a trade that sent Raimel Tapia to the Blue Jays. He’s long been a big power threat in the box but often undercuts the value of that power with a lack of walks and low on-base percentages. His first year in Colorado followed that pattern, as he hit 19 home runs but walked in just 4.5% of his plate appearances, barely half of the 8.2% league average. He finished the season with a .259/.299/.425 batting line and a wRC+ of 88, indicating he was 12% below league average.

Grichuk primarily played right field for Colorado last year but also saw significant time in center. He and Yonathan Daza seemed poised to be the most likely candidates for center field work this year. If Grichuk has to miss any time, that could leave Daza as the primary option in the middle, with Kris Bryant in left and Charlie Blackmon in right, though both of those players will likely see some time as the designated hitter as well. Younger players like Sean Bouchard, Nolan Jones or Michael Toglia could factor in to the mix as well or perhaps non-roster invitee Harold Castro. The club’s top prospect is outfielder Zac Veen. He could reach the big leagues at some point this year, but he’s only played 34 Double-A games thus far and struggled mightily in those, suggesting he still needs more time on the farm.

It doesn’t seem like Grichuk is expecting to miss much or any of the regular season, but it’s one more challenge for a club that won 68 games last year and had a very quiet offseason.
