It’s the least I can do for your part in last year!!!@JustinCToscano No!!!!! @TylerMatzek you can have my elbow!!! It’s the least I can do for your part in last year!!!Some fans are wishing Matzek a speedy recovery and are hopeful he will return in 2024 as a stronger pitcher. They noticed that his velocity had dropped this year and figured something was wrong.Other fans are questioning why it took the Atlanta Braves until the end of the regular season to look at Matzek. With his velocity being down for the majority of the year, the Braves could have had him checked out earlier. Now that he will have Tommy John late in the season, he won't be available for next year.The Atlanta Braves need to shake the rust offDivision Series - Philadelphia Phillies v Atlanta Braves - Game 1The Braves dropped their first game of the NLDS to the red-hot Philadelphia Phillies on Tuesday with a score of 6-7. The bye in the Wild Card didn't seem to do them too many favors. With time off since their last regular-season game, they didn't find their groove until the middle of the game against the Phillies.They almost made a spectacular comeback, scoring three runs in the ninth inning. However, the rally fell short as they didn't get that last run across the plate.Atlanta Braves' ace Max Fried didn't have a great outing on the mound. He only pitched 3.1 innings, giving up eight hits and six runs. It was surprising for someone who is ranked seventh in the league in the regular season ERA with a 2.48 ERA.The Braves will look to bounce back in game two of the NLDS on Wednesday evening.
