The Celtics went with one of their smallest lineups this season which, in the end, proved to be just enough for a 115-104 victory over the Atlanta Hawks on Wednesday night at TD Garden. The victory ended a five-game losing skid for Boston (20-39), while the Hawks (26-31) continue to fade from being a team fighting for home court in the first round of the playoffs to a team that's clinging to the eighth and final playoff slot after having lost 10 of 11. Going with a small lineup is nothing unusual for NBA teams. For the Celtics and the Hawks, injuries left them little choice but to downsize. Boston was playing without Avery Bradley (ankle), Jared Sullinger (concussion), Vitor Faverani (knee) and Kelly Olynyk (sprained toe). For the Hawks, the injuries were just as significant. In addition to starters Paul Millsap (knee) and Al Horford (right pectoral muscle), the Hawks were also missing Pero Antic (right ankle), Gustavo Ayon (shoulder) and John Jenkins (back). As much as those players were surely missed by their respective teams, the game was about players in the shadows most of this season taking center stage for this one night, this one opportunity to play the role of difference-maker. No one took to this more than Boston's Jerryd Bayless, who finished with a season-high 29 points, bettering his previous high of 22 points set against the Celtics on Nov. 27 when he played for the Memphis Grizzlies. Still, Bayless' big night didn't seem all that likely considering how the game began. The Celtics could not have played much worse than they did to start the game with the Hawks opening with a 23-8 run.
