The Philadelphia Phillies are the hottest team in baseball, though they will be without their first baseman the next few days. Tuesday afternoon the club announced Rhys Hoskins has been placed on the 10-day injured list with a groin injury, retroactive to Aug. 7. Outfielder Mickey Moniak was called up in a corresponding move.

Hoskins has been nursing the groin issue for some time now. He sat out last weekend's series against the Pirates, returned to pinch-hit and start three games against the Nationals last week, then sat out this past weekend's series against the Mets. Hoskins doubled in the go-ahead run last Thursday and didn't run well.

"It's not to the point where it was when he hurt it the first time," manager Joe Girardi told reporters, including Corey Seidman of NBC Sports Philadelphia, prior to the Mets series. "Part of it is me telling him to conserve it, I told him to be smart. But he's probably going to deal with this for a while and we've got to try to keep him good enough to keep him off the IL."  

Obviously the groin injury has not improved -- The Athletic's Matt Gelb says Hoskins took batting practice and ground balls Tuesday, but didn't come through as well as the team hoped -- and Hoskins is heading to the injured list. He has not played since Aug. 5, though injured list stints can only be backdated a maximum of three days, so Aug. 7 it is. He's eligible to be activated Aug. 17, when the Phillies start a road trip in Arizona.

Hoskins, 28, is hitting .244/.332/.509 with 24 home runs this season, including .318/.438/.718 with seven home runs in 26 games since July 1. Utility man Brad Miller has stepped in at first base while Hoskins has dealt with the groin issue.

The Phillies go into Tuesday's series opener with the Dodgers having won their last eight games. They've surged into first place in the NL East.
